Re: Boolean Data Type in C++ 80 80

The built-in Boolean data type in C++, bool, is quite simple: it is a data type which can hold one of two values, true or false. It can be used to hold a truth value for comparisons:

bool overflow = false;

while (!overflow)
    //  ... do some things 

    overflow = (foo > bar);

    // ... do some more things

In this case, it is used becausse there are actions both before and after the place where the value is checked, so it cannot be in just the conditional of the while() loop.

It is most often used as the return value for a function that returns a true or false result based on some test.
