hi? i was trying out this program, could someone please check this program and explain how the output generates the 10 numbers ..are these numbers stored in the compiler memory, and where did the -1.#J come from and what does it mean..

Also, could you check if the code style is adequate, if not can you suggest any improvements.

Thanks

cheers,

SAAB
