The do...while loop is a variant of the while loop with one important difference: the body of do...while loop is executed once before the condition is checked. Its syntax is: do { // body of loop; } while (condition);

Dec 12, 2024 · In C++, the do-while loop is an exit-controlled loop that repeatedly executes a block of code at least once and continues executing as long as a given condition remains true.

The for and while loops in C++ are entry-controlled loops, while the do-while loop is an exit-controlled loop. Not to worry; it is explained immediately following this section in this post. Update Expression (s): The update expression modifies the value (s) of the loop variable (s).
