Program to-copy-contents-of-one-file-to-another

This C program uses file input/output functions like fopen, getc, putc, fclose to copy the contents of one text file named abc.txt to another file named xyz.txt. It opens abc.txt for reading and xyz.txt for writing, then uses a while loop to read each character from the input file using getc and write it to the output file using putc until the end of file is reached, at which point it closes both files. The program was written by Gursharan Singh Tatla and contained on Page 1.
