Loops can execute a block of code as long as a specified condition is reached. Loops are handy because they save time, reduce errors, and they make code more readable. The while loop loops through a block of code as long as a specified condition is true:

The while loop will iterate while the user input can't be parsed to an int. When the user input is parsed to int the loop exits by returning the number entered by the user.

Jul 28, 2011 · As an example of where it's clearer to use break than a flag, consider: doStuffNeededAtStartOfLoop(); int input = getSomeInput(); if (testCondition(input)) break; actOnInput(input); Now let's force it to use a flag: doStuffNeededAtStartOfLoop(); int input = getSomeInput(); if (testCondition(input)) running = false; else. actOnInput(input);
