   Explain the concept of nested if-else statements in programming.

• Nested if-else statements can only have one if statement inside another.

• Nested if-else statements are used to create loops in programming.

• Nested if-else statements provide a way to handle complex decision-making scenarios by nesting one if-else statement inside another.

• Nested if-else statements are not supported in most programming languages.

1.       What is the advantage of using a switch case statement over multiple if-else statement?

• Switch case statements are less flexible.

• Switch case statements are harder to read and understand.
