What is the purpose of an If-Else statement?

The purpose of an If-Else statement is to control the flow of a program based on a condition. When the condition evaluated in the If statement is true, the code block associated with that If statement is executed. If the condition is false, the code within the Else block is executed instead. This allows for decision-making in a program, enabling it to perform different actions based on the specified conditions.

This is essential in programming because it allows for flexibility and control, enabling developers to write more dynamic and responsive code. For example, an If-Else statement can be used to check user input or sensor data, executing different responses depending on whether the criteria are met. The ability to branch the execution path of a program is a fundamental concept in programming logic.

Other options mentioned do not align with the function of an If-Else statement. Loops, variable definitions, and function calls serve different purposes, and understanding how they operate separately is crucial for structured programming.
