What is the primary purpose of the do-while loop?

To create infinite loops
To execute code a specific number of times
To repeat code until a certain condition is met
To skip iterations based on a condition

The primary purpose of the do-while loop in C++ is to repeat a block of code until a certain condition is met. Unlike the while loop, a do-while loop guarantees that the loop body is executed at least once before checking the condition. It's useful when you want to ensure a piece of code runs at least once.
