5.6 Implementing Algorithms
The implementation of an algorithm is carried out by writing the code in an ap-
propriate programming language, such as Ada, Fortran, Eiffel, C, C++, or Java .
Programming languages have well-defined syntax and semantic rules. The syntax
is defined by a set of grammar rules and a vocabulary (a set of words). The legal
sentences are constructed using sentences in the form of statements. There are two
groups of words that ...
