A Do While Loop is a control flow statement used in programming that allows a block of code to be executed repeatedly as long as a specified condition remains true. The loop begins by executing the code inside it at least once, and then it checks the condition. If the condition is true, the loop continues; if false, the loop stops. This type of loop is useful when you want to ensure that a certain action is performed at least once before checking if it should be repeated. Common programming languages that support Do While Loops include Java, C++, and Python.
