Boolean Expressions

You can also combine boolean statements. For example, the player is alive in a game while his health_value > 0 AND stamina_value > 0. You can write an expression like this in C++ using the and operator:

main.cpp


              12345678910
            
#include <iostream>

int main()
{
    short health_value = 50;
    short stamina_value = 70;
    
    if (health_value > 0 and stamina_value > 0)
        std::cout << "Player is alive!";
}

Let's look at the and operator in greater detail. It returns true if both statements are true. If at least one statement is false, the and operator will return false.

And if you want the player to have health_value > 0 OR stamina_value > 0 you can use the or operator.

main.cpp


              12345678910
            
#include <iostream>

int main()
{
    short health_value = 0;
    short stamina_value = 70;
    
    if (health_value > 0 or stamina_value > 0)
        std::cout << "There is still health or stamina left!";
}
