Basic Control Flow

Using Boolean Variables

The bool type can hold exactly two values, denoted false and true.
Boolean variables are named after George Boole (1815-1864), a pioneer in the study of logic.

Example:

bool more = true;
while (more)
{
   cin >> next;
   if (cin.fail())
      more = false;
   else
   {
       // process next
   }
}

Don't:

while(more == false) /* don't */

while(more != false) /* don't */
