csharp.net loops

  • Iteration statements enable the user to perform the same set of statements repeatedly until a specific condition is met.
  • Iteration statements also known as looping statements.
  • The statement present in the Loop body is executed repetitively until specified condition gets false as soon as condition gets false program control comes outside the loop body and the statement present immediate after the loop’s body gets executed.
  • For example if we want to print counting up to 100. To do this we have to write 100 statements but using loop we can perform this operation to write 3 or 4 lines of code.
