Programming in C: Increment and Decrement

Last time we took a look at how to handle user input, today we will be looking at different ways to increment and decrement values in C. Incrementing or decrementing a value, like an integer, is increase or decreasing the value by one or more. Suppose you have the following program:

#include <stdio.h>
int main(void) 
{
  int number = 1;
printf("The number is: %d", number);
  
number++;
  printf(The number incremented by 1 is: %d", number);

number--;
  printf(The number decremented by 1 is: %d", number);

}

The way to increment and decrement a number above is the simplest way. There are many ways of incrementing or decrementing a number, as seen below:

Increment

variable_name = variable_name + 1;

variable_name += 1;

++variable_name;

Decrement 

variable_name = variable_name - 1;

variable_name -= 1;

--variable_name;

The difference between having the ++ or -- before or after the variable name are as follows:

ariable_name++; - Uses the variable then increments.
++variable_name; - Increments the value, then uses the variable.

variable_name--; - Uses the variable then decrements.
--variable_name; - Decrements the value, then uses the variable.
