Using loops, you can execute code as many times as you want—which is one of the things computers excel at. The most basic loop is the for loop statement, and here's what this statement looks like in general:

for (initialization;

If the test is false, the loop ends (often the test condition checks whether the value in the loop index exceeds a specified maximum value). On the other hand, if the test condition ...
