What is C?
A high-level programming language developed by Dennis Ritchie at Bell Labs in the mid 1970s. Although originally designed as a systems programming language, C has proved to be a powerful and flexible language that can be used for a variety of applications, from business programs to engineering. C is a particularly popular language for personal computer programmers because it is relatively small -- it requires less memory than other languages.
The first major program written in C was the UNIX operating system, and for many years C was considered to be inextricably linked with UNIX. Now, however, C is an important language independent of UNIX.
Although it is a high-level language, C is much closer to assembly language than are most other high-level languages. This closeness to the underlying machine language allows C programmers to write very efficient code. The low-level nature of C, however, can make the language difficult to use for some types of applications.
To write and exicute C program you need some step which is given below:-
- The #include directive
- Header files
- The main() function
- The return statement
- The exit() function
- The newline character (\n)
- The void data type
- Translating a C program into an executable file
A First C Program:- #include <stdio.h>
printf ("First C program.\n");
To run above program you need tuboc c. Open turboc c write above code and save it filename.c name.
To compile press Alt+F9.
To run program Press Ctrl+F9.
The Output will be "First C program."
