Switch Statement
Switch Statement
The C switch statement is a control flow statement that allows a program to execute different code blocks based on the value of an expression.
The syntax for a switch statement in C is as follows:
switch(expression) {
case value1:
/* code to be executed if expression is equal to value1 */
break;
case value2:
/* code to be executed if expression is equal to value2 */
break;
.
.
.
default:
/* code to be executed if none of the cases match */
}
The switch statement evaluates the expression and then compares it with each of the values listed in the case statements. If the expression matches a particular value, the code block associated with that case statement is executed. If none of the case statements match, the code block associated with the default statement is executed.
It’s important to note that each case statement must be terminated with a break statement, which tells the program to exit the switch statement and continue executing the code after the switch statement. If you forget to include a break statement, the program will “fall through” to the next case statement, which may not be what you intended.
