C Programming
C programming is a powerful general-purpose programming language.
C is the first complete programming language so it is know as a mother of programming language.
For a new programmer, it is good to start with C Programming.
C Programming History
- C is a programming language developed at AT&T (American Telephone & Telegraphy) Bell Laboratory of the USA in 1972, designed and written by Dennis Ritchie.
- In earlier days, programming were written in assembly level language. So, it had happened to write very big programs to perform specific tasks using assembly code.
- C language features were derived from an earlier language called “B” (Basic Combined Programming Language - BCPL).
- B language did not support some features like data types and structure etc. So, this was a drawback of B language. So, Dennis Ritchie developed C language by keeping most part of B language and adding many features that produced powerful and effective output.
- So, C language was invented for implementing UNIX operating system. Most of the UNIX components were rewritten in C.
- In 1978, Dennis Ritchie and Kernighan published the first edition “The C Programming Language” and commonly known as K&R C.
Why C ?
- C is a base of the programming language.
- C helps you to know the structure of the program.
- It helps you to learn syntax which can be used in C++, Java etc.
To run C programming, You should download a software Dev C++.
Then, write C program code and then save the file with extension .c and run the code.
To download Dev C++, go to this link DEV C++
Let's begin with the first program
- Once you download and install the software open it you will see something like this...
Note: Please click on the image to get clear view.
- Now Click on file and you will see the page like this.
- Now click on new and then source file or click ctrl + N to open new source file.
- This page is displayed.
- And write the following code :
#include<stdio.h>
int main()
{
printf("This is my first programming");
return 0;
}
- Save this code as myfirstprogram.c
- To run this program click on execute and click on compile and run.
- Following are the screenshots of the programm.
