loops
Loops of C-Programming language
Loop is a statement, it calls itself more than one time,
when the condition gets satisfied.
(or)
C loop statement is used when you want to execute
a block of code repeatedly with checked condition
before making an iteration.
By using loop we can reduce the duplicate statements.
Loops are divided into 3 types.
* while loop.
* do-while loop.
* for loop.
