There is a concept called "The Drunkard's Walk" or a "Random Walk". Reference of ConceptLinks to an external site.

The idea is that some things in life are not predictable but follow a random path. In mathematical terms, it is a path that consists of a succession of random steps. For example, the path traced by a molecule as it travels through a liquid or a gas, the search path of a foraging animal, the price of a stock, the financial status of a gambler.

Your program is going to simulate this using random numbers. This walk is only going to be in one dimension.

Imagine a bridge that is a certain number of "steps" wide. A robot is trying to cross the bridge. Unfortunately it has a defect which causes it not to be able to go straight forward but only steps to one side or the other.

The program's job is to ask the user how many steps they want to run the simulation, then display the outcome. The simulation ends either by finishing the number of steps the user requested, or by falling off the bridge on either side.
