Is there a way to break out of a while loop before the original condition is made false?

Question

Is there a way to break out of a while loop before the original condition is made false?

for example if i have:

while (a==true) 
{ 
    doSomething() ; 
    if (d==false) get out of loop ;
    doSomething_that_i_don't_want_done_if_d_is_false_but_do_if_a_and_d_are_true() ;
} 

Is there any way of doing this?

Answer 1

Use the break statement.

if (!d) break;

Note that you don't need to compare with true or false in a boolean expression.

Answer 2

break is the command you're looking for.

And don't compare to boolean constants - it really just obscures your meaning. Here's an alternate version:

while (a) 
{ 
    doSomething(); 
    if (!d)
        break;
    doSomething_that_i_don't_want_done_if_d_is_false_but_do_if_a_and_d_are_true();
} 

Answer 3

Try this:

if(d==false) break;

This is called an "unlabeled" break statement, and its purpose is to terminate while, for, and do-while loops.

Answer 4

break;
