Introduction

This year, we are going to implement, through a succession of assignments, a simple parking$-$lot simulator and

optimizer. For Assignment $1,$ we have modest goals though: we would like to read from a file the design and the

occupancy information of a parking lot, and perform some basic operations, for example, parking a car at a certain

spot in the lot. What you need to do in this assignment is illustrated with an example. Suppose we have a file

named parking. inf with the content shown in Figure $1.$
