If you want a user to enter exactly 20 values, which loop would be the best to use?
1. do-while
2. while
3. for
4. infinite
5. none of these

For loop

Explanation:

Using the for loop we can get the exact number of values/outcomes we require.

For example:    printf(enter 20 numbers");

                               for(int i=0; i<20;i++)

                               {

                                       scanf("%d", &number);

                                }

So, this is an implementation of for loop in C. Using it we can enter exact 20 numbers not less or more than that.

Therefore, for loop is the answer.
