Let’s take a look at our pre-decrement operator example. The pre-decrement operator decrements a given value before the action gets assigned.

Let’s examine our code.

#include <iostream>
int main(void) {
    int myNumber = 16;
    int myNewNumber = --myNumber;
    std::cout << myNewNumber << std::endl;
    std::cout << myNumber << std::endl;
    return 0;
}

As we compile and run we see 15 echoed out to the terminal.

The value of myNumber was 16 and when it is assigned with the pre-decrement operator we see that the new value is 15 as it is assigned into myNewNumber.

Next week we will dive into the Debuggin Pre-Decrement Operator.
