C Programming C programming is a popular computer programming language which is widely used for system and application software. Despite being fairly old programming language, C programming is widely used because of its efficiency and control. This tutorial is intended for beginners who does not have any prior knowledge or have very little knowledge of computer programming. All basic features of C programming language are included in detail with explanation and output to give you solid platform to understand C programming. C Programming Keywords and Identifiers Character set Character set are the set of alphabets, letters and some special characters that are valid in C language. Alphabets: Uppercase: A B C .................................... X Y Z Lowercase: a b c ...................................... x y z Digits: 0123456 89 Special Characters: , ' < & > { . } Special Characters in C language _ ( ) ; $ : % " ^ ! * / | - [ \ ] ~ # + White space Characters: blank space, new line, horizontal tab, carriage return and form feed Keywords: Keywords are the reserved words used in programming. Each keywords has fixed meaning and that cannot be changed by user. For example: int money; Here, int is a keyword that indicates, 'money' is of type integer. ?
