Lession - #2 C Overview
The UNIX operating system, the C compiler, and essentially all UNIX application programs have been written in C. C has now become a widely used professional language for various reasons −
- Easy to learn
- It produces efficient programs
- It can handle low-level activities
- It can be compiled on a variety of computer platforms
A C program can vary from 3 lines to millions of lines and it should be written into one or more text files with extension ".c"; for example, hello.c. You can use "vi", "vim" or any other text editor to write your C program into a file.
