Syntax and Structure of Switch Statement

What is Switch Statement?

Case Statement:

A switch statement typically consists of the following elements.

  • Switch expression: This is an expression that is evaluated to determine which case to execute. Commonly, it’s an integer or a character variable.
  • Case Statement: These statements define the different possible values the switch expression can take and the corresponding code to be executed if there’s a match.
  • Case block: This block contains the code to be executed based on the value of the switch expression.
  • Break statement: This statement terminates the execution of the case block once a matching case is found. Without a break, the program might continue executing code from subsequent cases.

The syntax and structure of switch-case statements are similar across languages, with slight syntactic variations. Here is a general template.

Code Snippet 
switch (switch_expression) {
  case value1:
    // Code to execute if switch_expression equals value1
    break;
  case value2:
    // Code to execute if switch_expression equals value2
    break;
  // ... more cases
  default:
    // Code to execute if no matching case is found (optional)
}

Now let’s dive into the details of each of the components of a switch-case statement.

Switch statement in Programming

Switch statement in programming enables the execution of different code blocks based on the value of an expression, providing a structured approach to handle multiple cases efficiently. It enhances code readability and simplifies decision-making processes, making it a valuable tool for managing program flow and facilitating branching logic in software development.
