What is general form of declaring a switch in C?

Answer 1

In C, a switch statement is used to execute one block of code among multiple choices based on the value of a variable. The general form of a switch statement is as follows:

switch (expression) {
    case constant1:
        // Code to execute for constant1
        break;
    case constant2:
        // Code to execute for constant2
        break;
    // Additional cases...
    default:
        // Code to execute if no cases match
}

The break statement is used to exit the switch after a case is executed, and the default case is optional, handling any values not matched by the specified cases.
