Program to copy 2 files whose names are given as command line arguments.

                                              To compile and execute the program, copy the code into a text file. Save the text file with the extinction .c (ex. program.c). Save your file in turboc2 or borland (it may your othe c-compiler). Now open you IDE (tc.exe) , goto file->pick file. Your source file will be loaded into IDE. Now you can compile and run the file easily.
