Why use loops in C language?. The looping simplifies the complex problems into the easy ones. It enables us to alter the flow of the program so that instead of writing the same code again and again, we can repeat the same code for a finite number of times. For example, if we need to print the first 10 natural numbers then, instead of using the . KNNL – Sections 26.1-26.5, 27.3. Nested Factors. Factor is Nested if its levels under different levels of another (Nesting) factor are not the same. Nesting Factor ≡ School, Nested Factor ≡ Teacher.
