Example program for fsetpos() function in C programming

 In c handling, fsetpos() function will be used to set the position of input file with the help of fsetpos() access that point.

If you use to fix the file indicator position at any time in the given file then we need to use the fsetpos() function.

 Return Value :- fsetpos() function return zero at the time of success or non zero at failure.
