Increment & Decrement Operators | ++ and -- Operator - C & C++ Programming
In this video, you will learn increment and decrement operators in C++. I will also teach you the difference between prefix and postfix usage of ++ and -- operators. Do stick till the end of this video. You will learn how the behavior of increment and decrement operators changes when used along with the assignment operator.
Understanding these operators is essential for anyone looking to become a proficient C++ programmer. They allow you to manipulate variables in a way that can make your code more concise and efficient. But how do they work, and when should you use them? I have got you covered!
++ operator, called the increment operator, increases the operand value by 1. Suppose I declare an int variable named count and assign a value of 0. After performing count++ or ++count, the value of count will change to 1. ++count or count++ is the same as count = count + 1.
- operator, called the decrement operator, decreases the operand value by 1. Suppose I declare an int variable named count and assign a value of 1. After performing count- or ==count, the value of count will change to 0. -count or count- is the same as count = count - 1.
The increment and decrement operators can be prefix or postfix. If the operator is used before the operand, it is called a prefix. E.g., ++count.
If the operator is used after the operand, it is called a postfix. E.g., count++.
In this video, I will cover the following topics:
1. The basics of increment (++) and decrement (--) operators
2. Post-increment and post-decrement vs. pre-increment and pre-decrement
3. Practical examples demonstrating how and when to use these operators
By the end, you'll have the knowledge and confidence to use increment and decrement operators effectively in your C++ projects.
