Thread: using the value returned from an int type function

Hello all

I have this int type function that returns a number. It returns the value 2 for now but later it will return more variety of values. How do I use the value it returned? I'm not sure of the proper syntax.

You can assign the returned value to a variable, or even use the function call as an expression.

Functions in C and C++ - Cprogramming.com

This is the code from the tutorial link you showed me. The function Multi returns x * y. How would I use what it returned?

I would need an extra variables to equal what "int mult (int x, int y)"returns.

What the tutorial does.

Code:

#include <iostream>

using namespace std;

int mult ( int x, int y );

int main()
{
  int x;
  int y;
  
  cout<<"Please input two numbers to be multiplied: ";
  cin>> x >> y;
  cin.ignore();
  cout<<"The product of your two numbers is "<< mult ( x, y ) <<"\n";
  cin.get();
}

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

What I need to do

Code:

#include <iostream>

using namespace std;

int mult ( int x, int y );

int main()
{
  int x;
  int y;
 int product;


  cout<<"Please input two numbers to be multiplied: ";
  cin>> x >> y;
  cin.ignore();
  mult(x,y) = product;
  cout<<"The product of your two numbers is "<< product <<"\n";
  cin.get();


}

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

It worked;

I tried in reverse at first which is why my program failed. I need sleep or my attention to details is getting sloppy either way thanks. I would have tried 8 new concepts, if you haven't noticed what I did wrong.
