C programming is an imperative procedural language. It was designed to compiled using a relatively straightforward compiler and it also provides the access to memory to provide language constructs to follow the machine instructions.

In this section, you will learn how to start with c programming and also I will explain this by using a simple and easy example program which prints the “Hello World”. Apart from this, you will also learn the below things:

Basic commands of c programming.
How to write a C program.
A simple C program with an output.
How to compile and execute a C program.

Basic commands of c programming

Below are the basic commands of C programming language:

#include : A command for the preprocessor to include the standard input output header file(stdio.h) from C library.ng a C program
int main(): Main function, from where execution of C program begins.

How to compile and execute a C program

Follow the below steps to compile and execute the C programs.

Step 1) Go to the path where you have saved your C programs.

Step 2) Assume you have saved your C programs in D drive, then run this command to compile your program D:\C Programs>tcc hello.c

Step 3) After execution of “tcc command”, just type the program name and hit the enter button.

D:\C Programs>hello
Hello

Simple Example:

#include <stdio.h>

int main()

{

/* Our first simple C basic program */

printf("Hello World! ");

getch();

return 0;

}

Output:

1	Hello World!

Program to accept input from user

Below program will take input from the user using scanf and print while program execute.

#include <stdio.h>

main()

{

int number;

printf("Please enter an integer\n");

scanf("%d",&number);

printf("You have entered number is: %d\n", number);

return 0;

}
