Loops in C

Before discussing various loops in 'C', it is necessary to understand about loop, what exactly it is. We use loop when we have to repeat a block of code. For many times, it is required to execute the same code a number of times for some cases. Then we take the help of loop. 
                         There are three types of loop:- 
                          1.  while
                          2.  dowhile
                          3.   for

                 There are two keywords which are important in loop. So, before studying loops in deep, lets see these two keywords. They are:-
 1. break
 2. continue

 1. Break
               We use break to terminate the loop. In other words, we can say that it is useful to get exit from a loop under some circumstances. This will be more clear in using loops in next chapters.

2. Continue                  Continue is a keyword that controls the flow of loops. Sippose we are executing a loop and hit a continue statement, the loop will stop its current iteration, update itself (in case of for loops) and begin to execute again from the top.
