lol need some help :D

Hello Ladies and Gentlemen, how are you all? I hope you all are good haha

now i wont waste your time in any formality etc and i'll get to the point.. our programming sir is a retard and he always give us work to do which he never taught us, for example i remember once in a class he defined "Array" and after just defining it, he told us to take 2 arrays and then swap it, LOLOL WTF? ok now he has given us a program which when executed will display this on screen


WELCOME
My Calculator
Version 1.0
Press any key to continue.......

now before i go ahead, wtf should i use when any key is press the menu should be displayed?

well here's the Menu

A........for Addition
S......for Subtraction
F.......for factorial
D........for division
G........for string operations
M........ for multiplication

now if u hit A or a a menu should come n do addition etc same for all which is easy but when u hit "G" another menu should come n it should display

String operations
R........Reverse
C........copy

and etc etc .. lol wtf? how do u do this? and also what do i need to put in start of program so when user press any key it should display the menu, n he also said after each thing is done for example if u hit a for addition n addiiton is done, it should ask u if u want to run it again or no, if u press y then it will run again if u hit n then it goes to menu, also he said "Do NOT use goto as its a poor programing practice" lol wtf so anyone who can help etc can post here




NOTE-:- PLEASE DO NOT POST IF YOU WOULD LIKE TO CRITICISE OR SAY SOME SMART CRAP LIKE "OMFG WE R NOT HERE TO DO UR HOMEWORK ETC" If you are not dumb you'll know that this is not doing my homework so yeah I repeat people who will criticise are not WELCOME to post, thanks

HOHO so waiting for some elite replies now :D

and yeah only 19 hours left to submit this program, out of these 19 hours i'll sleep for like 8 hours, and 2 hours ill enjoy / eat etc.. so 8+2 = 10 and 19-10 = 9 .. so you have 9 hours to reply if you would like to, after 9 hours please dont bother to reply as it will be of no importance

thanks :D

For this kind of thing, you would need to use a non-standard library. So, what compiler and operating system is involved here?

you should have guessed that when i said our programing sir is a retard, lol.. in this modern age he wants us to use Turbo C/cpp hahaha :) and i remember a friend doing it without using any library, this key thing i mean.. i know the library ur refering to honey its stdlib.h .. or maybe some else also but duno haha :) i want it to do it without any lib heh:D like if(choice==default) or something like that default(); or whatever i forgot it completely .. so tell me what u know ?

and also, from the pic of yours, are you a women or a male? sorry i cant differentiate from ur hair style, so tell me

Quote:

i know the library ur refering to honey its stdlib.h

That is a standard C library, though in this case you are talking about input, so it is <stdio.h> instead. The problem is that, using the command line, your users will be required to press enter, but you want them to be able to press any key.

It is not a picture of me, and I am a guy.

so how do you do it for press any key

Do you actually have any code written yet? I'm only asking because it doesn't seem like this assignment is very urgent for you.

QuantumPete

You will have to wait for someone who knows the best solution for this in Turbo C to give you the answer. In the mean time, you could try out one of the suggestions in the FAQ: How can I get input without having the user hit [Enter]?

quantam lol you dont know our programing sir, that retard is just like a army commander.. the way he orders us is like that of army generals.. once we were sitting in his class and it was 10:50 so he told us that "Submit this thing to me exactly and 11:00 and reach your next class at 11:01 immediatly" lol and he is so strict that dont ask.. once a student while in a exam just looked at the person sitting on the right side of him and he came and canceled his paper just like that lol :S now no one can even look above in his damn test.. as for the program, i can write different functions for it like add etc in 2 minutes, thats not a problem.. the problem is that thing when asking y/n to run program again and another problem is that press any key and other prob is this string operations thingi

Code:

---

#include <stdio.h>
#include <stdlib.h>
void multiply();
void divide();
void add();
void substract();

int main()
{
  int choise;
  printf("Calculator.\n");
  do                     
  {
  puts("MENU: \n");
  puts("1 to multiply.");
  puts("2 to divide.");
  puts("3 to add.");
  puts("4 to substract.");
  puts("5 to exit.");
  scanf(" &#37;d", &choise);
  switch (choise)
          {
          case(1) :
                    multiply();
                    break; //prevents other cases from executing
          case(2) :
                    divide();
                    break;
          case(3) :
                    add();
                    break;
          case(4) :
                    substract();
                    break;
          case(5) : exit(1);
                    break;
          }
  }
  while((choise < 1) ||(choise > 5));

  getchar();
  getchar();
  return 0;
}

void multiply()
{
 float a, b, c;
 puts("Enter numbers: ");
 scanf(" %f", &a);
 scanf(" %f", &b);
 c = a * b;
 printf("Answer: %f\n", c);
 return;
}

void divide()
{
 float a, b, c;
 puts("Enter numbers: ");
 scanf(" %f", &a);
 scanf(" %f", &b);
 c = a / b;
 printf("Answer: %f\n", c);
 return;
}

void add()
{
 float a, b, c;
 puts("Enter numbers: ");
 scanf(" %f", &a);
 scanf(" %f",  &b);
 c = a + b;
 printf("Answer: %f\n", c);
 return;
}

void substract()
{
 float a, b, c;
 puts("Enter numbers: ");
 scanf(" %f", &a);
 scanf(" %f", &b);
 c = a - b;
 printf("Answer: %f\n", c);
}

how do i add this "Do you want to run again y/n" thing into each of this? and what abt the key thing if u know hurry reply i gota go to play a game, totaly bored ;X
and also string operations

For a quick and dirt way for "press any key", system("pause") might do the trick.
As for the yes/no thingy, you make a loop. Loop while the user says "yes."
In case you don't know loops, there's good tutorials on the site.
Hang in there! Don't let your retard teacher get to you!

Whether your instructor is a bastard doesn't have anything to do with your programming and if he voids your exam for looking up, he'd probably not be too thrilled with you using this board to get your homework done!
What exactly is the problem you have with asking "y/n" and you'll need to give us more information on what this string operations thingy is!

QuantumPete

im going to play MOHAA and ra2 now, will be back later from gaming den.. if u guys could help plz do, just post that how can i add "if u want to run this program again? y/n" that option into each function ok n also tell me how to make those string operations if one press G a menu should come with string operations, R for reverse C for copy B for back etc..... and also how that key thing, ill check back when here thans

This would just take printf and scanf.

lol @ system("pause") uncle that system pause ........ is like getch(); haha i dont know how is it related for any key pressing hahahha :d anyway
quantum read above what i said, i want something that when a user press 1 for addition n addition is done like user put 2+2 n result is given 4, it should be asked from user if he want to run it again or no, if he do Y then it should run again and if he do N then it should go to menu
ok laters

and u all take a bath with cold water :) thanks

So, if you already know the answer why bother asking?

Yes it is... it shows "Press any key to continue" message. You wanted one, right?

Quote:

quantum read above what i said, i want something that when a user press 1 for addition n addition is done like user put 2+2 n result is given 4, it should be asked from user if he want to run it again or no, if he do Y then it should run again and if he do N then it should go to menu

---

So print out a message asking if the user wants to run it again and read the input.

haha lol ok when you come back read this:
after printing your great program intro ...
Calculator 1.0
blah blah
just call getch();
for you it will do, and don't worry the least about portability haha lol

in each function print the message:
do it again [y/n]
and put the code in a loop also. a do while loop is good here.
in string function you should do almost exact thing as in main.
just print the menu in a loop, read choice, do blah haha lol
lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol

If your instructor has "given you a program", as you say, then post it, already!

The thing is, short of writing out the whole program, there's no easy answer to such a vague request as you've made.

And we don't do whole programs hardly at all, because we like to see you learn to program, not just copy from a forum, and also, it takes a lot more time.

On this forum, you should ALWAYS post the code you have (or pseudo-code if you have no code), and then tell us what *specific* problem you're having, and how to fix THAT problem.

You'll wind up getting a few fixes, and suggestions, but a whole program - not likely.

Code:

---

#include <stdio.h>
#include <conio.h>

void menu(void);
void addition(void);
void division(void);
void factorial(void);
void multiplication(void);
void subtraction(void);
void stringOps(void);

char A[256] = {'\0'};

int main()  {

  printf("\n\nWelcome to My Calculator");
//etc.

  fflush(stdin); //others will tell you it's crap. I'll tell you I use Turbo C/C++ still, and Borland
                        //recommends using fflush(stdin).
  printf("\n\nPress Any Key to Continue");
  while(!kbhit); //do nothing, notice the semi-colon here.
   
  menu();


  return 1;

}
/*everything loops out from your menu() and comes back to it, as well*/

void menu()  {
  char ch;
 
  do  {

      printf("\n\n Calculator Main Menu. Please Select One Type of Problem, or Q to Quit")

      printf("\n\n A........for Addition\n S......for Subtraction\n F.......for factorial\n D........for division");
      printf("\n G........for string operations\n M........ for multiplication");

      fflush(stdin);
      scanf("%c" &ch);
      ch = toupper(ch);  //check the header needed for this,

      switch (ch)  {
        case 'A': addition(); break;
        case 'S': subtraction(); break;
        case 'F': factorial(); break;
        case 'D':division(); break;
        case 'G': stringOps(); break;
        case 'M': multiplication(); break;
        default:
            printf("\n I didn't understand that choice, please choose again");
      }


  }while(ch != 'Q');
}

---

That's all the time I've got right now. Good luck w your program.







}

Don't recommend undefined behavior to others. Recommended or not, there are other ways of doing it.
It's really time you got rid of Turbo C.

hahah i just got back and i found most of you are so funny.. now listen to the question carefully please.. "WHERE ON EARTH DID I SAID THAT I WANT THAT ........ TO APPEAR ON SCREEN THAT MY CALCULATOR WELCOME MSG?" ROFLLLLLLLLLLLL I only said that when that msg is display there will be a msg "Press any key" Then if a user press'es any key like shift a b c or whatever he hits, THE MENU should open lololol and btw when i got back from playing mohaa so my brain was fresh so i wrote this ........ in like 5 minutes

LOLLOLOLOLOL I R LULZ

Please stop 'loling', why are you using conio.h?

And this isnt' C... I'd suggest you study instead of playing 'mohaa'.

Code:

---

switch(ch1)
    {
      case'A':
      case'a':

---

What's wrong with,

Code:

---

switch(tolower(ch1))
{
    case 'a':

    ...
}

---

Code:

---

void main()

---

Naughty.

Stop lolling all the time and listen to what people are saying.

oh btw ty Adak for your reply, it was somewhat close but your reply was the most appropriate amoung all others, thanks to all others as well (just for the formality) not that they did something great haha :)

Edited to remove anti-semitic comment. I'll leave the rudeness in so people know who they're dealing with. -- CornedBee

uncle, when you only do 'a' then when a user hits 'a' (small case) only then will it work, when user hits "A" capital A then it wont work, thats why uncle u need to do it for both ahhahahahha ?? ?? :D

edit: zacs7 sorry but i cant stop loling at you guys, dont say stuff that dont make me lol and i wont lol :)

oh i forgot to mention in the above post .. "And its not c" LOOOOOOOOOL this is perfecty c, just edit cout to printf and cin to scanf .. and as for libraries, they can be included in both c or cpp so what are you talking about? UNCLE :)

> this is perfecty c, just edit cout to printf and cin to scanf
Er... you know how stupid that sounds?

And please stop calling me Uncle, unless you are actually my nephew -- which I hope not.

That's what the tolower() function is for. It transforms a char from uppercase to lowercase.

lol haha
hey i sent you a pm lol
but you seem so lol that you did not notice it yet lol
when will you be done with your mohaaa lol

lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol lol
