Code writing issues Part 2...

Okay, okay...I tried to write the code myself...I figured someone would be cool enough to do me a favor, but I guess there's some moral programming "code" I am unaware of. Anyway, here's what I have. Please judge and modify and add and erase to your hearts content.

Code:

---

#include <stdio.h>
#include <time.h>
#include <stdlib.h>

void doOneSet(char opc)
{
  char str[100] = { 0 };
 
  switch(opc)
  {
      int i;
     
      case '+': for(i=0; i < 5; i++){
       
                    sprintf(str, "%2d + %2d = ", rand() % 100, rand() % 100);
                    puts(str);
                }
               
                break;
  }
} 

int main(void)
{
  srand((unsigned)time(NULL));
 
  doOneSet('+');       
 
  return 0;
}



switch(opc){

  int i, n1, n2;

  case '+': for(i=0; i < 5; i++){

              n1 = rand() % 100; n2 = rand() % 100;
              sprintf(str, "%2d + %2d = %3d", n1, n2, n1 + n2);
              puts(str);
            }

            break;
}

So what are you trying to do?

A switch statement must be in a function.

Just to help you about this...
What if I asked you to make me a string parser in c++, and offering you music or something like that? What would you do? Write me whole program?
Then think about monastery, they need people like you. :p

I see that you are new to forum, so lete me give you few advices about posting topics :

I.
Why have you made new thread for this? It should go in the old one, where you first posted and where people asked you to show your effort.
I don't see any reason for opening new thread.

II.
When making new thread, think of some meaningful name for it. What does "Code writing issues" tell you ? For me it means that someone has problems/questions about something. When I opened thread, I saw completely different thing.


Don't be offended becouse of this, I just wanted to teach you some basic principles about forums. :)


Nice to see that you started writing code. :)
That is the only way people will help you... If they see that you are trying.
Remember, never ask someone to write you full program. Except if you are offering car/money/wife :D .


Greetings,

You must have missed that they locked/closed the last one
he was force to make a new one.

I excuse for my stupidity...
Haven't seen this locked icon.
...thanks for telling me this horny vector :):)

:) np lol,

Jaybo684,
This is too easy...
I've made it in C++, it's not full, but you can translate it in C, and add what you need.
The rules are pretty strict... ( http://www.santarosa.edu/~ssarkar/ci...ture%20Diagram )
You will have much work about this.............

WARNING, 122 line code block ahead :)

thsi code interested me to so i made my own version,
very different yet not :

Code:

---

#include <iostream>
#include <iomanip>
#include <fstream>
#include <ctime>

using namespace std;

int main()
{
        srand(time(NULL));
        time_t start, end;
        double diff;
        double correct = 0;
        double all = 0;
        cout << "Press a Key to Start your 20 Question Exam!" << endl << endl;
        cin.get();
        time (&start);
        ofstream out ("mathlog.txt");
        while(all != 20)
        {
                int total = 0;
                int rand1 = rand()%100;
                int rand2 = rand()%100;
                cout << rand1 << " + " << rand2 << " = ";
                out << rand1 << " + " << rand2 << " = ";
                cin >> total;
                out << total << endl;
                if((rand1 + rand2) == total)
                {
                        cout << "Correct!" << endl;
                        out << "Correct!" << endl;
                        correct++;
                }
                else
                {
                        cout << "Incorrect!" << endl;
                        out << "Incorrect!" << endl;
                }
                all++;
        }
        time (&end);
        diff = difftime (end,start);
        cout << "You got " << correct << " correct out of " << all << " for an accuracy rate of " << setprecision(0) << ((correct/all)*100) << endl;
        out << "You got " << correct << " correct out of " << all << " for an accuracy rate of " << setprecision(0) << ((correct/all)*100) << endl;
        cout << "This test took you : " << diff << " seconds." << endl;
        out << "This test took you : " << diff << " seconds." << endl;
        cout << "Done!" << endl;

        cin.get();

        return 0;
}

vector, you can find more of those at http://www.santarosa.edu/~ssarkar/cis10sum05/ .Just go to assignments.
@Jaybo
What do you have now?

Jaybo, are you programming in C or C++?

Code:

---

sprintf(str, "%2d + %2d = %3d", n1, n2, n1 + n2);
puts(str);

---

Second, haven't you missed the deadline for this particular project?

Third why are you two posting solutions to his homework? Let him try it out?

:confused:

>>> but I guess there's some moral programming "code" I am unaware of.

Homework policy

It is posted at the top of the forums, by the board rules. You did read the rules didn't you?
