What are the other forms of switch statement in C?

The expression can be integer expression or a character expression.

Value-1,2,n are case labels which are used to identify each case individually.

A block is nothing but multiple statements which are grouped for a particular case.

What is the use of switch statements in C programming?

– We first prompt the user to enter the desired operator. This input is then stored in the char variable named oper. – We then prompt the user to enter two numbers, which are stored in the float variables num1 and num2. – The switch statement is then used to check the operator entered by the user: If the user enters +, addition is performed on the numbers.

What are the limitations of switch statement in C?

Do one thing. In other words,for an individual case,rather than adding a huge block of code,call a function.

When using enums,avoid using a “default” or “else” case. The beauty of enum switches is that you get not only cleaner code but better enforcement.

Avoid early escaping. I’ve gone back and forth on this myself.
