Loop structure

1.       What can be done by the loop structure?

      Ans: A statement could be executed many times.

2.        How many parts are there in the For-loop structure? Explain.

      Ans: There are three parts in the For-loop structure. They are

1.     initialization part;

2.     conditional part;

3.     increment part;

3.                    For-loop structure define with figure    (For-loop structure wK fv‡e KvR K‡i Zv wP‡Îi mvnv‡h¨ eY©bv Ki|)

 main(){

   int k;

   for(k = 5; k<= 20; k = k+2){

    printf("%4d",k);

   }
