void is used by functions that do not return a value. For example:
// This function returns an integer, which you can use in other functions
int addTwoNumbers(int a, int b)
{
return(a + b);
}
// This function does not return a value, so we declare it as a void
void printSum(int a, int b)
{
cout << a << " + " << b << " = " << addTwoNumbers(a, b) << endl;
// Note that attempting to return a value here will cause an error.
}
