Answer 1

I use it commonly when I need to handle the input. Of course it can use on more rather than just handle the input.

For example: I want to make a simple calculator, so I need 2 numbers and a character as operator. The valid operator for this porgram is +-*/ , but what if the user input 4 & 4? & isn't the valid operator for it. So we can do the following:

switch(operator) {
case '+': a+b: break;
case '-': a-b; break;
case '*': a*b; break;
case '/': a/b; break;
default: cout << "Invalid operator"; break;
}

Answer 2

BTW the switch statement is not a loop.

• The default Case
In a switch statement, the optional 'default' case can be used to perform a task when none of the cases is determined to be true.
