What is do loop?

A do loop is a type of loop in programming that is used to repeatedly execute a block of code as long as a certain condition is true. It is also known as a do-while loop. The structure of a do loop consists of a do keyword followed by a block of code to be executed, and a while keyword followed by a condition that is checked at the end of each iteration.

If the condition is true, the loop will execute again, and if it is false, the loop will exit and the program will continue to the next statement. This type of loop is often used in situations where the loop must be executed at least once, even if the condition is initially false.

The syntax of a do loop may vary slightly depending on the programming language being used, but the basic structure and functionality is similar across most languages. Some languages also support variations of the do loop, such as the do-until loop, which executes the loop until a certain condition is met, rather than while a condition is true.
