Functions

[wander95]

I'm trying to to make a program that displays other functions that displays other functions. To do that I have to get a function to return strings and ints at the same time. How do I do that? If there is a way....

Something kinda like this.....
int function(int, string);

you can't get a function to return more than 1 thing.
You can have a function that takes the address of a variable though, and this will allow for changing that variables data, rather than just changing a copy of the variable.

int function(int i, string& str)
{
   // this makes a copy of i
   // this IS the address of string

   // manipulate both
   i++;
   getline(cin,str);
   return i;
}

int main()
{
   int x =9;
   string str="Hello"
   x = function(x, str);

   return 0;
}

enter: World.

x = 10;
str = "World."
