This is a sample from my original program to pin point complilation/
linking problem. There is not output on running this program. This program
compiled and execited on Solais Unix by issuing command:
CC test.C individual.C parameter.C
a.out
But it is not compiled using gcc. The compilation message and listing of
files are given below. Oblige me by redering solution and poined my
mistake.
