Thread: lol need some help :D

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.

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

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':

    ...
}

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 ?? ??

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

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
