I remember after my First year of graduation, I was doing some GUI programmings in C on a Intel386 machine :P, with only dos and C compiler installed. After some days me and my friend Paresh came with idea of making Windows operating environment on top of DOS. something like windows 3.0. Just for programming exercise in summer vacation.

Initially I was using C graphics library for creating windows and displaying text, Icons etc. Later I wrote my own library of graphics functions. And created few fonts also.

anyways all this for just giving the background of problem.
Problem Statement :
Design an application which will be running on machine in non-windowed environment (DOS command prompt or unix shell) to display Advertising Text (If some simple drawings it will be gr8) . The text can scroll also (Horizontally or Vertically) something similar to LED Display screen showing at Railway stations and Airports.

Program should be flexible enough to take different text as input and no of times to scroll the text.

This Sunday morning I brought one rectangular (cuboid for the puritans) cake. Me and my kid brother decided to divide the cake in two equal parts in evening. So I kept the cake in fridge.

In noon my neighbor's daughter came( No need to say she is very fond of Cake) cut a rectangular piece from cake....

In eve Sonu ( my brother) found the a rectangular piece of cake is missing . And since we have to divide cake in two equal parts, How can he divide cake in exact two equal parts in single cut?

please help him :)
