  History of C language

The C programming language was developed at AT & T's Bell Laboratories of USA in 1972. It was designed and written by a man named Dennis Ritchie. In the late seventies C began to replace the more familier languages of that time like PL/I, ALGOL etc.

Rules for writing C program:

1. Blank spaces can be inserted between two words. However, blank spaces are not allowed between a single word.
2. Usually all C statements are entered in small case letters.
3. The different part of C statements can be split over multiple lines.
4. Any C statement always ends with a semicolon ( ; ).

Data Types:

 Data is possibly one word which has been used with gay abandon by programmers. It is almost impossible for a programmer to talk for two minutes about computing without saying data in one context or the other. There are data types, data objects, data flow , data bases.
