Study Notes

Purpose of if-else Structure

The if-else structure is used to make decisions in a program, allowing it to execute different blocks of code based on specific conditions.

If Syntax

In the syntax 'if(condition) statement;', the 'condition' represents a Boolean expression that is evaluated to either true or false.

Evaluating to False

If the condition in the if statement evaluates to false, the code within the if block is skipped, and the program continues to execute the next line of code.

Else Part

The else part of the if-else structure specifies an alternative block of code to execute when the condition in the if statement evaluates to false.
The else part is optional, and it provides a way to handle situations where the condition is not met.
