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:

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

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