Process will be as follows while the conditional expression 1 is satisfied.
• Execution line 2 is continuously executed while the conditional expression 2 is not
satisfied.
• Once the conditional expression is satisfied, it will go out of the loop by break (not
executing execution line 2), and execution line 3 is executed.
break
switch ( )
{
case constant 1:
;
break;
case constant 2:
;
break;
}
;
When the conditional expression 2 matches the constant 1, it will halt the
determination of constant 2 by break after executing execution line 1, and
process will move to execution line 3.

It will exit the script, and execute the next parts or script.
