Mastering Loop Structures

A loop in programming is a control structure that allows a block of code to be repeated multiple times. Its purpose is to automate repetitive tasks and reduce code duplication.

A do.while loop is a post-test loop in which the condition is checked after the loop body is executed. It is used when you want the loop body to execute at least once, regardless of the initial condition.

The syntax of a do.while loop is as follows: do { // statements } while (condition);
