It can do whatever we know how to order it to perform. It can follow analysis but it has no power of anticipating any analytical relations or truths. Its province is to assist us in making available what we are already acquainted with. Ada Augusta Countess of Lovelace Introduction This chapter introduces the C language and gives enough detail to allow you to handle simple programs involving expression assignments and console input output I O . The details of assignment and expressions are similar to those of most other high-level languages. Every language has its own console I O syntax so if you are not familiar with C that may look new and different to you. Introduction to C Language is the only instrument of science. Samuel Johnson This section gives an overview of the C programming language. ORIGINS OF THE C .
