break

The break keyword is used to break out of a do, for, or while loop. It is also used to finish each clause of a switch statement, keeping the program from “falling through” to the next case in the code. An example:

     while( x < 100 ) {
       if( x < 0 )
         break;
       cout << x << endl;
       x++;
     }

A given break statement will break out of only the closest loop, no further. If you have a triply-nested for loop, for example, you might want to include extra logic or a goto statement to break out of the loop.
