A computer programming language is used by a programmer to express the solution to a problem in terms that the computer system can understand. The chapter looks at how to solve a small problem using the computer programming language Ada 95.
Solving a problem by implementing the solution using a computer programming language is a meticulous process. In essence the problem is expressed in terms of a very stylized language in which every detail must be correct. However, this is a rewarding process both in the sense of achievement when the program is completed, and usually the eventual financial reward obtained for the effort.
