The switch statement provides an alternative to multiple if/else statements when testing for multiple conditions. It evaluates an expression once and compares it to case values, executing the code block for the matching case. The syntax includes a switch expression, cases for possible values, code blocks for each case, and a default if no case matches.

- 1. In cases when you need to test for multiple conditions, writing if else statements for each condition might not be the best solution. The switch statement is used to perform different actions based on different conditions. Syntax The switch expression is evaluated once. The value of the expression is compared with the values of each case. If there is a match, the associated block of code is executed. Switch switch (expression) { case n1: statements break; case n2: statements break; default: statements }
