closing a function

Oct 11th, 2008

I am a noob therefore this question is hopefully very easy for someone to answer!

in my code i have asked a question if the answer is yes i want the program to continue onto the next question (this is fine) if however the answer no or enter an incorrect answer then i wasn the program to end! i know about if statements so i am ok with that i just need the line of code i put in the no if statement or the else to make the program finish.

i hope this is clear thank you for any cooperation

Many programmers don't like putting return statements in the middle of functions. So here's another way to do it

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
int main()
{
   char answer;
    cout << "Do you feel sexy today?";
    cin >> answer;
    if( answer == 'Y')
    {
                // now do other things
 
    }
    return 0; // end of function
}
int main()
{
   char answer;
    cout << "Do you feel sexy today?";
    cin >> answer;
    if( answer == 'Y')
    {
                // now do other things

    }
    return 0; // end of function
}

For future reference you should also realize that you could do this with a while loop for example if u want to keep going through the loop until a button is pushed that will make the button true as such:

int main() {
        while(buttonPushed() == false) { 
        //perform your loop
        }
return 0:
}
int main() {
        while(buttonPushed() == false) { 
        //perform your loop
        }
return 0:
}
