How can we ensure the execution of a block of code at least once?
The `while` loop in C programming provides a solution to this need. It is a control flow statement that executes a set of statements repeatedly as long as a specified condition remains `true`. By utilizing the `while` loop with the `execute at least once` approach, we can guarantee that the code block within the loop will execute at least once, even if the condition becomes `false` immediately after the first iteration.
In this approach, we initialize a variable to `true` before entering the `while` loop. Within the loop, we first execute the desired code block and then check the condition. If the condition is still `true`, the loop continues; otherwise, it exits. This setup ensures that the code block executes at least once, regardless of the condition's outcome.
The `while` loop with `execute at least once` is particularly useful in scenarios where certain tasks or initializations need to be performed before the actual loop condition becomes `true`. It offers greater flexibility and control over the execution flow, making it a valuable tool in C programming.
