Let’s dive into our code.
#include <iostream>
int main(void) {
int myNumber = 16;
int myNewNumber = ++myNumber;
std::cout << myNewNumber << std::endl;
return 0;
}
To compile this we simply type:
g++ example10.cpp -o example10
./example10
We see 16 and 17 printed to the screen.
Let’s break it down:
We create a variable myNumber = 16 to which we create another variable myNewNumber which post-increments the value of myNumber. We see that when we execute our code it shows 16 as the value of myNewNumber and 17 as the value of __myNumber __as myNewNumber does not get incremented as only myNumber get incremented as it is a post operator.
When we post-increment the value of the variable is incremented after assigning it to another variable. For example myNumber is 16 so it gets incremented after being assigned to myNewNumber so therefore we get 17.
Next week we will dive into Debugging Post-Increment Operator.
