Switch Case With Break Statement

switch() can only contain char and int.

break is used to exit from switch statement. switch case can be without default case.
In switch case char variable is always initialized within ”(single quotes). If there is no break statement then the cases following the matched case other than default will get executed. If there is no any match case then default will be executed.

Syntax

switch(expression)
{
    case value1:
    	block1;
    	break;
    case value2:
    	block2;
    	break;
    case value3:
    	block3;
    	break;
    case value4:
    	block4;
   	    break;
    default:
   	    defaultblock;
    	break;
}

void main()
{
    char grade;
