C++ Booleans
C++ Booleans
For this, C++ has a bool datatype, which can take the values true (1) or false (0). A boolean variable is declared with the bool keyword and can only take the values true or false:
Example
#include <iostream>
using namespace std;int main() {
bool isCodingFun = true;
bool isError = false;
cout << isCodingFun << "\n";
cout << isError;
return 0;
}
Output:
1
0
Boolean Expression
A Boolean expression is a C++ expression that returns a boolean value: 1 (true) or 0 (false). You can use a comparison operator, such as the greater than (>) operator to find out if an expression (or a variable) is true.
Example
#include <iostream>
using namespace std;int main() {
int x = 10;
int y = 9;
cout << (x > y); // returns 1 (true), because 10 is higher than 9
return 0;
}
Output:
1
