Procedures and Functions,ming language. As problems become more complex, it is better to break them into a hierarchy of steps. In doing this we describe a problem using a structure of blocks, each of which is subdivided into smaller blocks until we have units small enough to handle in terms of the programming language.

Arrays,roved a problem in these examples but such an approach would become cumbersome very rapidly when we consider problems involving vectors and matrices. Data analysis becomes practically impossible unless there is some way of storing and manipulating whole blocks of numerical values.

First Steps,The above is an example of a Pascal program which reads two numbers and prints their average. It is a mixture of words, numbers, punctuation and other characters.

Numerical Errors and Accuracy,Results obtained from numerical calculations on a computer are subject to two sources of possible error. One of these is the unavoidable error which results from the way that numbers are stored on a computer, while the other error is one deliberately incurred by the numerical method we have chosen.
