do-while loop

The do-while loop in C programming is a control flow statement that executes a block of code at least once and then continues to repeat it based on a specified condition. Grasping the concept of the do-while loop is pivotal for any C programmer who aims to write versatile and effective code.

The syntax of the do-while loop is as follows-

do {
   // statements
} while(condition);

In this structure, the statements inside the loop are executed before the 'condition' is tested. If the condition is true, the loop is repeated. This process continues until the condition evaluates to false.

The do-while loop is unique among loop constructs as it ensures that the loop body is executed at least once, regardless of the condition's truthfulness. It comes in handy when the condition needs to be evaluated after the loop's execution, such as in menu-driven programs.

Despite its straightforward usage, it's crucial to avoid pitfalls like infinite loops and ensure your loops have an appropriate exit condition. By mastering the do-while loop, you can add more depth to your programs and make them more interactive and dynamic.
