Explain the Break Statement - Computer Programming?

The break statement is used as an interrupt to the normal flow of control this statement causes as exit from the switch statement. It can be used within a while, for, do - while or switch statement and the break statement causes the control to come out of the entire loop. A break within a loop must always be protected within an if statement which provides the test to control the exit condition.

char ch;

ch=getchar();

switch(ch)

{

case 'a' :

case 'e' :

case 'i'  :

case 'o'            :

 case 'u'            :{

printf("Vowel");

break;

}

default :{

printf("Not a vowel");        

break;

 }

}

If the input take place to be 'a' or 'e', 'i', 'o', 'u' , the control goes to that particular case and prints "Vowel". By executing the break statement can't will come out of the loop.
