Switch Statement in C

A switch statement in C is a control structure used to execute one block of code from multiple options based on the value of an expression. It simplifies complex conditional statements like multiple if-else blocks.

Syntax:

Key Points:

1. Expression: The switch evaluates an integer or character expression.
2. Cases: Each case represents a possible value for the expression.
3. Break Statement: Used to exit the switch block. Without break, execution continues to the next case (fall-through behavior).
4. Default Case: Executes if no matching case is found (optional but recommended).

Example:

Output:

Key Benefits:

1. Easier to read and maintain than multiple if-else statements.
2. Efficient for handling multiple fixed values.

Limitations:

1. Cannot evaluate ranges or complex conditions (use if-else for that).
2. The expression must evaluate to an integer or character type.

The switch statement is a powerful tool for managing multi-condition branching in C programs.
