Part 47 – Post-Decrement Operator

This week we will address the post-decrement operator. 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 we see 16 and 15 printed out respectively.

We see that in this scenario myNewNumber does get decremented as myNumber— takes the value of 16 and reduces it to 15.

Next week we will dive into the Debugging Post-Decrement Operator.
