Pointers and Polynomials,ogram segment, they allocate a fixed amount of space into which we can store values. We have met simple types such as REAL and INTEGER, and structured types such as ARRAYs and RECORDs. Each of these has a specific role to play and contributes to the richness and versatility of the Pascal language. H

Simulating Queues,ken to serve customers is described by one or more given service distributions. The queue discipline determines the way in which customers move through the system, the simplest being a first come first served system. Knowledge of these three things is sufficient to permit modelling of the system mat

Sets, can represent more than one value of a given scalar type. It is defined as follows. where . is the type of the possible values that can be entered in the sets of the defined type. The . must be scalar and may be either a user-defined scalar type, an existing scalar type, such as CHAR, or a subrange

Introduction,text has evolved out of an introductory course on programming for mathematicians and hence the problems considered are related to the work that mathematics students are likely to cover during their first year in higher education.

Numerical Calculus,) and f(.) would become indistinguishable on the computer and this would lead to gross inaccuracies. Therefore, by reducing . in the classical theoretical manner, we can only achieve an accuracy within the limits of that allowed by the computer we are using.

Records, Complex Numbers and the Fourier Transform,erhaps as a character, H or L say, in such a way that both pieces of information are firmly linked together. Such structures are called RECORDS. When we come to consider queues in a later chapter, this ability to define a structure of linked elements of mixed types is very useful.

Sets, number of elements in the set of possible elements defined by the base type. The maximum number of elements that a set can contain varies from one implementation of Pascal to another. However, most modern versions of Pascal allow at least the full character set of 256 values. Other types allowed must have ordinal values within the range allowed.

Programming Structures,in order to produce a solution to a problem. The objective in programming a computer is to produce the most efficient and accurate solution. This is not necessarily the easiest or the most natural solution to the problem.
