A Boolean, from my understanding is just a true or false. Yes or no. 0 or 1
Simple as that. it's used to determine if something is or isn't.

if (5+5==10){
return true;
} else {
return false;
}
// if used productively then its used like this...
int main(){
int age;
bool isAble = false // able to drive initially false
cout << "Age :" << endl;
cin age;
if (age >= 17){
isAble = true;
} else if (age < 17){
isAble = false;
}
while(isAble){
cout << endl << "user is able to drive";
}
while(!isAble){
cout << endl << "user unable to drive";
}
return 0;
}

I don't see how that is productive because the expressions are bools too. Not sure what the while loops are for, they won't terminate by themselves. You also over-complicated a simple if-else statement.

either true or false nothing more

Remember that despite being a binary value, it is still of the size of a byte because it needs to be allocated in the memory

i understand your point, i was just trying to find an excuse to use them in a basic, understandable program. i can do much better than this
