What is the primary difference between a while loop and a do$-$while loop in programming?

A while loop always executes its body at least once, while a do$-$while loop may not execute its body at all.

A do$-$while loop always executes its body at least once, while a while loop may not execute its body at all.

A while loop checks its condition after executing the loop body, while a do$-$while loop checks its condition before executing the loop body.

There is no difference between a while loop and a do$-$while loop; they are interchangeable in all situations.
