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.
