Question regarding switches, I think.

averyniceguy (2)
This is a snippet of a program I'm working on. The idea is that it switches between active and not active every time a password is entered. Could you show me a more efficient way of doing this? Also, I do not understand the necessity of bool if I can use int.

  void corrPassw() {

		if (password==setpw1 && a==1) {
			
			cout << "\n\033[0;32mFunction 1 is active.\033[0m\n";
			a = 2;
			
		}
		else if (password==setpw2 && b==1) {
			
			cout << "\n\033[0;32mFunction 2 is active.\033[0m\n";
			b = 2;
			
		}
		else if (password==setpw1 && a==2) {
			
			cout << "\n\033[0;31mFunction 1 is not active.\n\033[0m";
			a = 1;
			
		}
		else if (password==setpw2 && b==2) {
			
			cout << "\n\033[0;31mFunction 2 is not active.\n\033[0m";
			b = 1;
			
		}

	return;
}
int main () {

	a = 1;
	b = 1;

Nope.

Also, I do not understand the necessity of bool if I can use int.
I don't see any bools.

I used int instead of bool, and I don't understand the point of using bool in the first place, that's what I'm wondering.

Using bool you can toggle active/inactive easily using the logical NOT (!) operator (snippet follows):

bool active = true;

.
active = !active;  // now is false
