switch case

The switch case statement is a control structure in programming that allows a program to evaluate an expression and execute different code blocks depending on the value of the expression. It is used to simplify complex decision-making processes and replace multiple if-else statements.

The basic syntax of a switch case statement is:

switch(expression) {
    case value1:
        // code block executed if expression matches value1
        break;
    case value2:
        // code block executed if expression matches value2
        break;
    ...
    default:
        // code block executed if expression doesn't match any case
        break;
}

The switch statement evaluates the expression and compares it to each case value. If there is a match, the code block associated with that case is executed. If there is no match, the code block associated with the default case is executed.

The break statement is used to exit the switch statement after a case has been executed. If a break statement is not used, the code will continue to execute through the subsequent cases until a break statement is encountered or the end of the switch statement is reached.
