First program of C language (Hello World)

C is a powerful and widely used programming language that can run on various platforms. It is also the basis of many other languages such as C++, Java, and Python. In this blog, I will show you how to write a simple C program that prints “Hello, world!” on the screen, and explain the basic concepts and syntax of C. This blog is suitable for beginners who want to learn C programming from scratch, as well as for experienced programmers who want to refresh their skills. By the end of this blog, you will be able to write your own C programs and understand how they work. If you are interested in learning C programming, please read on and follow the steps. I hope you enjoy this blog and find it useful. 😊



code : 

 

#include<stdio.h>

int main() {

printf("hello world\n");

return 0;

}


This is a simple C program that prints the string “hello world” followed by a newline character to the standard output. Here is an explanation of each line of the code:

  1. #include<stdio.h>: This line includes the stdio.h header file, which contains the declarations for the printf function used in the program.
  2. int main() {: This line defines the main function, which is the entry point of the program.
  3. printf("hello world\n"); : This line calls the printf function to print the string “hello world” followed by a newline character (\n) to the standard output.
  4. return 0; : This line returns 0 from the main function, indicating that the program has executed successfully.
  5. }: This line marks the end of the main function.

Exploring Pascal's Triangle in C: A Code Breakdown

Introduction: Pascal's Triangle, a beautiful mathematical construct, has fascinated mathematicians and computer scientists alike for centuries. Named after the French mathematician Blaise Pascal, this triangular array of numbers holds the key to a multitude of mathematical and combinatorial mysteries. In this blog post, we'll delve into a C program that calculates and prints rows of Pascal's Triangle based on user input. We'll break down the code, step by step, to understand how it works. #include <stdio.h> int fact(int n) {          int factorial = 1;          for (int i = 2; i <= n; i++) {         factorial *= i;     }     return factorial; } int main() {     printf("How many rows do you want to be printed?\n");     int k;     scanf("%d", &k);     for (int i = 0; i < k; i++) {         for (int j = 0; j <= i; j++) { ...
