How does break statement work?

Question

If i write break statement in for loop then will variable be updated and then for loop exits,or after just excecution of break statement for loop exits? for e.g

for(i=0;i<100;i++){
//do something something
if(i==50){
break;
}

what will be the value of i after for loop exit?

Note: there is a `}` missing. – wildplasser Jun 22 '13 at 11:15 — wildplasser, Jun 22 '13 at 11:15

why don't you just add a printf after the loop? – anishsane Jun 22 '13 at 11:44 — anishsane, Jun 22 '13 at 11:44

When the break statement is encountered inside a loop, the loop is immediately terminated and program control resumes at the next statement following the loop.It can be used to terminate a case in the switch statement

The value will be 50.

The for loop can be described in general terms like this:

for(INIT; CONDITION; UPDATE)
  BODY

and it can be replaced with the equivalent while loop, like this:

INIT
while(CONDITION)
{
  BODY
  UPDATE
}

So, since your break is in the BODY, the UPDATE is not run, and the value 50 remains.

if(i==50);

i Will be 50
