Write a program which simulates a random walk

• Start at the origin and use your computer to take a two dimensional random walk with unit steps.

• After each step calculate R, your exact distance from the origin and record it together with N, the total number of steps up to that point.

• Plot R vs. . Is the relation linear?
• Try this with different methods for generating 2-D unit steps and (if available) with different random number generators. Can you see any difference?

Some source code available in: C, FORTRAN
