OMG can some please help?

My code wont work even though it looks like it should.
Could some one please help me?
I'm learning some functions so this will help me practice.

Code:

#include <iostream>
#include <stdlib.h>

using namespace std;

int answer;

int add (int a, int b)
{
    answer = a + b;
    return (answer);
}
int subtract (int c, int d)
{
    answer = c - d;
    return (answer);
}
int multiply (int e, int f)
{
    answer = e * f;
    return (answer);
}
int divide (int g, int h)
{
    answer = g / h;
    return (answer);
}

int main ()
{
    int pick1, pick2;
    cin >> pick1, pick2;
    cout << add (pick1, pick2);
    cout << subtract (pick1, pick2);
    cout << multiply (pick1, pick2);
    cout << divide (pick1, pick2);
    
    system("pause");
    return 0;
}

Please help.
THanks

What do you mean it won't work? Also, what compiler? I used Dev-C++ 4.9.8.0 and it worked fine. But, you should add some line breaks so you can tell the answers apart (unless there's a reason for that). Also, what is the point of answer? You can just use:

Code:

return number operation number;
//Like
return A * B;

Here's some code that works fine on Dev-C++:

Code:

#include <iostream>

int Add( int A, int B )
{
  return A + B;
}
int Subtract( int C, int D )
{
  return C - D;
}
int Multiply( int E, int F )
{
  return E * F;
}
int Divide( int G, int H )
{
  return G / H;
}

int main ()
{
  int Number1, Number2;
  std::cout << "Enter the numbers: ";
  std::cin >> Number1 >> Number2;
  std::cout << Add( Number1, Number2 ) << std::endl;
  std::cout << Subtract( Number1, Number2 ) << std::endl;
  std::cout << Multiply( Number1, Number2 ) << std::endl;
  std::cout << Divide( Number1, Number2 ) << std::endl;
  std::cin.get();
  std::cin.get();
  return 0;
}

Note you can still use using namespace std; system( "PAUSE" ); and answer (although it doesn't need to be global). Also, you can, in the std::cin statement, using the comma instead of an additional >>. You should also probably put a prompt, as it makes more sense.

THe code works fine but it displays the wrong answers.

Im using the newest version of Dev c++

ok its works now geeze.
in the cin part I had :

cin >> pick1, pick2

should have had :

cin >> pick1 >> pick2

lol

>My code wont work even though it looks like it should.

Code:

#include <iostream>
#include <conio.h>

using namespace std;

int answer;

int add (int a, int b)
{
    int _answer = a + b;
    return _answer;
}
int subtract (int c, int d)
{
    int _answer = c - d;
    return _answer;
}
int multiply (int e, int f)
{
    int _answer = e * f;
    return _answer;
}
int divide (int g, int h)
{
    int _answer = g / h;
    return _answer;
}

int main ()
{
    int pick1, pick2;
    cin >> pick1 >> pick2;
    cout << add (pick1, pick2) << "\n";
    cout << subtract (pick1, pick2) << "\n";
    cout << multiply (pick1, pick2) << "\n";
    cout << divide (pick1, pick2) << "\n";

    getch();
  return 0;
}

>The code works fine but it displays the wrong answers.
It was because you added no whitespace between the functions, therefore you saw one big string of numbers, instead of numbers seperated by whitespace.

EDIT:Nvm, you are correct in your answer.

Where are the function prototypes?

They're not needed if the function definitions are placed before main()

Really? is that the same for C?

Maybe, I guess, most likely, I don't do C.
It just that when the function is called within the main, the compiler need to check if the parameters match. That's way if you define the function after the main(), the prototype is required before main().

Yup im a noob at programming but I undersand that .
That completely true alpha.

Im not sure about C though

You always need to in C.

You sure? I've never received complaints from GCC when I don't prototype my functions, even if I use -Wall.

Ahh no i'm sorry. I misinterpreted an error, my sincerest apologies to out to you for leading you in the wrong direction...hate it when I do that..

Its ok Tronic.
Your code worked but I just made mine do the same thing with less code.

And that is a waste of a post. Try to avoid doing that, because the mods will consider it post-whoring.
