switch case

Switch case is a programming construct used to evaluate a variable or an expression against a set of possible values and execute a corresponding block of code. It allows the program to take different actions based on the value of a variable or an expression. The switch statement contains multiple case statements that represent the different possible values of the variable or expression being evaluated. When the switch statement is executed, the program checks the value of the variable or expression against each case statement until it finds a match. Once a match is found, the corresponding block of code is executed. If no match is found, a default block of code may be executed. Switch case statements are often used in programming languages such as C, C++, and Java.
