introduction to c

Dennis Ritchie

C is a most popular and beginner friendly programming language. C language is  developed by an american computer scientist Dennis Ritchie at bell laboratories in  1972. c language is considered as middle level language .c language is commonly  used for application development, system programming and embedded systems.

features of c language

c language provides low level access to memory which allows programmers to write code efficiently. c is a portable language. c also provides high level features such as structured programming constructs (like loops  and conditionals) and support functions and libraries these features makes c language suitable  for developing software applications.

why you should learn c language ?

learning c language provides many benefits that can enhance your programming skills and open up various opportunities in computer science and software development field. c is a foundational language in computer science which provides deep understanding of foundational programming concepts like variables, data types, loops, functions and memory management. it is helpful  to learning other languages because it shares similar concept and syntax.

example of c language

#include<stdio.h>

int main()

{

printf("welcome");

return 0;

}

In this example, # is a preprocessor directive and it is including <stdio.h>  header file which provides declaration for input and output function such as scanf() and printf() , main is a function which is entry  point of programme , execution of programme starts from main function. { (open curely braces) it marks the beginning of the main function. then printf() is a funcion  which is used to display the output on the screen , basically the message written in double quotes will be displayed on the screen it will display welcome. } (close curely braces) indicates end of main function.
