Here is one problem for all you programming freaks to try out.

1. Write a C/C++ (GNU) program that prints its own source code on executing.

Please give it a good thought before looking at the solution. My Solution:- for C | for C++

If you have a better solution than this please mail it to me. Or you can put it up in my Guest Book

Another one to set you thinking.

2. Write a C/C++ (GNU) program that outputs the code of a program which on executes prints the source of the first program. Its like this:- Let the programs be proga.c and progb.c

• $cc proga.c
• $a.out > progb.c
• $cc progb.c
• $a.out ( Output of which is proga.c )
