Introduction to C Programming

🤔What is Programming ?​

Providing clear instructions to the computer to perform specific operations. Programming is the process of instructions that tell a computer how to perform a tasks.

Different Programming Languages 💻​

C,C++,Java,Python,Kotlin,Javascript,Ruby,Typescript,C#,etc.

What is C Programming?​

C is a general-purpose programming language. C programming was created by Dennis Ritchie at the Bell Laboratories in 1972.

🤔What is Compiler?​

A compiler is a software program that converts source code written in a high-level language into low-level machine language.

💻 Example 1 :

#include <stdio.h>
int main()
{
    printf("Hello world!!!");

    return 0;
}

⚙️ Output :

Hello world!!!

Program Explanation:​

Line 1: #defines path directory include means add .h defines header file. Header files means code. <stdio.h> stands for Standard Input Output. #include <stdio.h> support input output file like printf() and scanf(). printf( ) function display output on screen scanf() function take input from user.

Line 2: int means return type of your function. main() it is the first function of every C program that is responsible for starting the execution and termination of the program.

Line 3: { is used to start of the function.

Line 4: printf ("Hello world"); printf() is a function used to print output text to the screen. Our example output is "Hello World". ; semicolon used to terminate any statement.

Line 5: return 0; return 0 means that the program will be executed successfully.

Line 6: } closing curly bracket is used to end the main function.

💻 Example 2 :

 #include <stdio.h>
int main()
{

    printf("Hello Students👋");
    printf("Are you interested in ICGP?");

    return 0;
}

⚙️ Output :

Hello Students👋 Are you interested in ICGP?

Example 3 :

#include <stdio.h>
int main()
{
    printf("My name is Suraj.");
    printf("I love teaching.");
    printf("I write code.");

    return 0;
}

⚙️ Output :

My name is Suraj.I love teaching.I write code.

New Line Character​

\n is a newline character. \n is used for create a new line or break a current line.

Example 4 :

#include <stdio.h>
int main()
 {
    printf("My name is Suraj.\n");
    printf("I love teaching.");
    printf("\n I write code.");

    return 0;
}

⚙️ Output :

My name is Suraj. I love teaching. I write code.
