So far in college the hardest conceptual program was the Child Twin Pointer Technique of organizing files using COBOL. Extremely easy to code and pretty easy concept too. If I was to be in an interview, and completed the next assignment I would mention it as the hardest. It is a Inverted KSAM file, with a non-unique secondary key using COBOL and I think it may use JCL.
1. To solve a classical sudoku (9*9 grid) in C.
2. Though lines of code are not as much as the first program, a program which implements Steganography (using text and windows bit map files) is very much a practical one. (both encoding and decoding logic are implemented in C and there is VB implemented front end to seletct files with ease.)
