Introduction

• C is a general-purpose computer programming language for use with the Unix operating system
• B is "typeless" language; C provides a variety of data types
• Fundamental data types are integer, character & floating point
• Hierarchy of derived data types created with pointers, arrays, structures and unions
• C provides the fundamental control-flow constructions required for well-structured programs: 
• statement grouping
• decision making (if-else)
• selecting one of a set of possible cases (switch)
• looping with termination test at the top (while, for)
• looping with termination test at the bottom (do)
• early loop exit (break)
