How to end the program in a function.

[Helpful stalker]

How do I end a program in another function besides int main?

like for example

#include <iostream>
using namespace std;


void myfunc() {
	
}

int main(){
int a = 2;

if(a == 2);
  myfunc();

cout << "Words";


cin.get();
return 0;
}

How would I make it so instead of printing "words" on the screen after the function ends, I just end the program in the myfunc?

[turb_]

[cpp]
#include <cstdlib>

void myfunc() {
exit(0);
}
[/cpp]

or alternatively:

[cpp]
void myfunc() {
int lol = 1 / 0;
}
[/cpp]

It worked :]

Thanks man.

Actually, that doesn't necessarily even throw a hardware exception. I recall someone saying that on some PowerPC processors it actually just sets the value to 0 and continues happily.

Throw the exception yourself :3

Exactly

I know from first hand experience that the NDS' ARM processor(s) do that :P

Because the method is "void" you don't need to return anything :) , Might help you...

This is probably why it's undefined behavior in C++.

returning in a function =/= ending the program

I know, but for future reference. I assumed the question was already answered.

I use

void myfunc() {
exit(1);
}

I'd just like to say that exit(0) is an evil that shouldn't be used 90% of the time (unless you want to just say "fuck it, os, clean up my shit for me" - not usually the best choice)

int func(int par)
{
    if(par > 9)
        return 1;
    else return 0;
}

int main()
{
    if(func(12) == 0)
        return 0;
    else
    {
        while(true)
            std::cout<<"I like turtles";
    }
    return 0;
}

I don't like how you are not using spaces between your operators :ohdear:

He's only doing it for the << operator on cout, so if anything, he's just being inconsistent.
