Thread: Returning Multiple Values

Sure thing honey; this'll work:

Code:

#include <iostream>
using namespace std;

void gimmeStuff(int *a, int *b){
   *a = 5;
   *b = 6;
}

int main(void){
   int x=0;
   int y=0;
   gimmeStuff(&x,&y);
   cout << "X is now "<<x<<" and Y is now "<<y<<endl;
   return 0;
}

Another possible way to return multiple pieces of data to a calling function, besides passing multiple parameters to the function by reference, is to return an object (like an instance of a user defined class or struct) or to use the struct as the parameter, passing it by reference of course.

Or you could use references

Code:

#include <iostream>
using namespace std;

void swap(int &var1,int &var2)
{
     int temp = var1;
     var1 = var2;
     var2 = temp;
}

int main()
{
    int abc = 1;
    int def = 2;
    swap(abc,def);
    cout << abc << def << endl;
}

I haven't checked that
