C++ Reference

while

Syntax:

    while( condition ) {
    statement-list;
    }

The while keyword is used as a looping construct that will evaluate the statement-list as long as condition is true. Note that if the condition starts off as false, the statement-list will never be executed. (You can use a do loop to guarantee that the statement-list will be executed at least once.) For example:

     bool done = false;
     while( !done ) {
       ProcessData();
       if( StopLooping() ) {
         done = true;
       }
     }
