Boolean represents just two values, i.e. True/1 or False/0.
A bool Data Type can accept only true or false.
#include <iostream>
using namespace std;
int main() {
bool x = true;
bool y = false;
cout << x << endl;
cout << y;
return 0;
}
So, in the above code, we have created a variable named x of Boolean data type and initialised it with value true and internally true gets converted to 1.
bool x = true;
And created one more variable called y of Boolean data type and initialised it with value false and internally false gets converted to 0.
bool y = false;
But if we want to initialise a Boolean type variable with anything other than true/false, it would end up with an error.
