If Else Statement

An if else statement is a fundamental control flow construct in programming that allows conditional execution of code blocks based on boolean expressions. It evaluates a condition and executes one block of code if the condition is true, and optionally another block if it is false, enabling decision-making in programs.

Also known as: if-then-else, conditional statement, if-else, if else, if...else

Why learn If Else Statement?

Developers should learn if else statements as they are essential for implementing logic and handling different scenarios in code, such as validating user input, controlling program flow, or managing error conditions. They are used in virtually all programming languages for tasks like branching, filtering data, and creating responsive applications.
