Unlike for loops, while loops do not allow you to declare or assign the variable used in the conditions. • The loop statements while, do-while, and for allow us execute a statement(s) over and over. The iteration (for, while, and do-while loop) statements allows a set of instruction to be performed repeatedly until a certain condition is fulfilled. When the condition becomes false, program control passes to the line immediately following the loop. using System.Collections.Generic;
