Increment And Decrement Operators

Introduction

Before we begin with iterations let's strengthen our understanding of Increment and decrement operators. Although they are not directly linked with iterations but are widely used in loops. Increment and decrement operators are fundamental tools in programming languages that allow you to modify the value of a variable by incrementing or decrementing it by a specific amount. These operators are commonly used in loops, arithmetic calculations, and other scenarios where you need to update a variable's value. In this article, we will explore the increment and decrement operators in detail, understand their behavior, and provide examples to demonstrate their usage.

Understanding Increment Operator (++)

The increment operator (++) is used to increase the value of a variable by 1. It can be applied to both numeric and character variables. The operator can be placed before the variable (pre-increment) or after the variable (post-increment). The behavior of the operator differs depending on its placement.

Pre-increment (++variable)

In pre-increment, the variable is incremented first, and then its updated value is used in the expression where it appears.

Post-increment (variable++)

In post-increment, the variable is used in the expression where it appears, and then its value is incremented.

Understanding Decrement Operator (--)

The decrement operator (--) is similar to the increment operator but decreases the value of a variable by 1. It follows the same pre-decrement (--) and post-decrement (--) syntax as the increment operator.
