How to Understand Repetition in C Language 

Loop Control Instructions: The programs that we have developed so far used either a sequential or a decision control instructions. In this article, we learn about loops, types of loops and structure of loops.

So, Loops is…..

In programming, we frequently need to perform an action over and over, often with variations in the details each time. 

The versatility of a computer lies in its ability to perform a set of instructions repeatedly. This involves repeating some portion of the program either a specified number of times or until a particular condition is satisfied. This repetitive operation is done through a loop control instruction

There is three-way to repeat a part of a program. They are:

1.      Using a while statement.

2.      Using for statement.

3.      Using do-while statement.

Structure of loops:

1.      While loop:

2.      For loop:

3.      Do-while loop:

Some important point for creating loop control instructions:

·         I++ increments value by 1.

·         I- -decrement value of 1.

·         If j=++I; first increment I, then assigned the increment value to j.

·         If j=- -I; first assign the current value of I to j, then increments j.

Note: there are no **,// and %% operators.
