Do While

Question

When is do-while usually used?

Answer 1

do-while is an EXIT control loop. It first executes the statement for one time and then checks the given condition.
It is mostly used to make our program user-friendly that is for asking the user like "do you want to continue (y/n) : ".
If the user enters y it repeats again.
and if the user enters n it gets out of loop as you have set the condition as while(ch==y);
