bookBooleans

Let’s discuss boolean (or logical) data type in more detail. The variable type of bool can take only two values - True (1) or False (0). The boolean can be used when we want to check some logical conditions in our code. For example, you want to know if the variable x is bigger than y to use this information by looking for the difference between them.

For this reason, there are some logical operators you can use in comparison:

Use them in boolean expressions, which return the output as a boolean value: True. If the condition holds or False otherwise.

For example:

12345
int x = 5; int y = 4; cout << (x > y) << endl; // will return true, because 5 is higher than 4 cout << (x <= 5) << endl; // will return true, because x is equal to 5 cout << ("hello" == "Hello"); // will return false, because these string aren't the equal
copy

The program returned 1 where the statement was true and 0 where was false.

Check if the variable `x` is equal to the variable `y` and if `x` is greater than `450`.

#include
using namespace std;

int main() {
    int x = 24 * 25;
    int y = 19 * 32;
    cout << (x
y) << endl;
    cout << (x
450);
    return 0;
}

Tudo estava claro?

Como podemos melhorá-lo?
