In which scenario is a Do-While loop most appropriately used as compared to other loop structures?

  • When you know the exact number of iterations required.
  • When you need a loop with a fixed number of iterations.
  • When you need to execute the loop body at least once.
  • When you want to iterate through a collection.
A do-while loop is most appropriate when you need to execute the loop body at least once, regardless of the condition. It is useful when you want to ensure that a certain part of your code runs before checking the loop condition. This is different from other loop structures like for and while, where the loop body may not execute if the initial condition is false.
