We can divide the work among programmers using functions. We can easily debug or can find bugs in any program using functions. Function Aspects : There are 3 aspects of function :- Declaration Definition Call  there two type of function  1. library function 2. user define function  in this all doubt is clear  #include <stdio.h> int   sum  (  int   a  ,  int   b ) {     return   a + b ; } int   printstar (  int   n  )      {     char   i ;      ...
