Thread: I cant get functions to work!

I don't know of a random function but i know there's rand. I've never heard of mult though. What does that function do?

Here Dan try this

Code:

#include <iostream>
#include <time.h>
#include <stdlib.h>
using namespace std;

unsigned mult (int x, int y);

int main()
{
  int input;
  cout<<"--Main Menu--"<<endl;
  cout<<"1. Play Game"<<endl;
  cout<<"2. Exit"<<endl;
  cout<<"Please enter your option: ";
  cin>>input;
  switch (input)
  {
    case 1:
      int input2;
      int x;
      int y;
      int z;
	  srand (time (NULL));			
	  
	  x = (rand () % 10) + 1; // makes random # between 1 and 10
	  y = (rand () % 10) + 1;
      z = mult (x, y);
      cout<<"What is "<<x<<"x"<<y<<endl;
      cin>>input2;
                  if (input2 == z)
	  {
		  cout << "Concratulations you won!";
	  }
	  else
	  {
		  cout << "Sorry, you lost!" << endl;
	  }
	  break;
	  return 0;
    case 2:
      return 0;
    default:
      cout<<"Error! Exiting Game!"<<endl;
      return 0;
  }
  return 0;
}

unsigned int mult (int x, int y)
{
	return x * y;
}

I edited alot but now it works fine.
If you want an explaination about what I did just PM me or email me at : [email protected]

Code:

z=mult(int x, int y);

This is incorrect, you don't specify variable type in function calls. It should be this:

Code:

z=mult(x,y);

Please don't do this. By taking the discussion out of the public forum, you are making it harder for everyone else to learn. People often search through old threads to get help, so it's always good to fully resolve the discussion where everyone can see it.

EDIT:
For information about random numbers, read the FAQ.

Sorry about that Benny,
I just thought it would be easier to explain to him over MSN messenger instead of typing in forums.

That's ok, everyone has to learn sometime.
