we are here to help you.

Switch case is another selection control statement (like if-else)

Now, let’s first understand, what is selection control statement.

These are used when you have to execute only one part of the code out many different parts
if a specific condition is specified.

  1. If-else:
    If(condition1){
    //Perform addition
    }
    else if (condition2){
    //Perform subtraction
    }
    else{
    //don’t perform anything
    }

Explanation:
If condition1 satisfies, addition would be performed,
If condition2 satisfies, subtraction
And if none of the condition 1 or condition 2 satisfies, do not perform anything.

2.switch case:
It is same as if else. But checks only for equality.

Int ch;
cin>>ch;
switch(ch){
case 2: cout<<“hello”;
break;
case 9: cout<<“hii”;
break;
default:cout<<“default”
}

Explanation:
Ch is a variable of type int.
If it’s value is 2, print hello
If it is 9, print hii
Default is like else of if-else
It is executed for considered cases that are mentioned.

It only checks for equality of a variable to a value.

Here, break is used to stop the compiler tonexecute any further inside switch block and exit it.
