🖥️ Hello World

This fun and quirky code animates the famous "Hello World" message one character at a time in your terminal. 🌟

📋 Overview

This program uses a simple loop and usleep to create a smooth, character-by-character reveal of the classic "Hello World" message. It's a great demonstration of basic C programming and terminal output manipulation.

🛠️ Code Explanation

Here's a breakdown of what the code does:

1. Initialization: The word array is initialized with spaces and then null-terminated to form an empty string.
2. Character Animation: Each character of "Hello World" is incremented from a space to its target character with a delay, creating an animation effect.

#include <stdio.h>
#include <unistd.h>

int main(void)
{
    char word[12];
    for (int i = 0; i < 11; i++) word[i] = ' ';
    word[11] = '\0';

    printf("\033[H\033[J"); 
    printf("%s\n", word);
    word[0] += 64;
    while (word[0] != 'h') { word[0]++; usleep(100000); printf("%s\n", word); }
    word[1] += 64;
    while (word[1] != 'e') { word[1]++; usleep(100000); printf("%s\n", word); }
    word[2] += 64;
    while (word[2] != 'l') { word[2]++; usleep(100000); printf("%s\n", word); }
    word[3] += 64;
    while (word[3] != 'l') { word[3]++; usleep(100000); printf("%s\n", word); }
    word[4] += 64;
    while (word[4] != 'o') { word[4]++; usleep(100000); printf("%s\n", word); }
    word[6] += 64;
    while (word[6] != 'w') { word[6]++; usleep(100000); printf("%s\n", word); }
    word[7] += 64;
    while (word[7] != 'o') { word[7]++; usleep(100000); printf("%s\n", word); }
    word[8] += 64;
    while (word[8] != 'r') { word[8]++; usleep(100000); printf("%s\n", word); }
    word[9] += 64;
    while (word[9] != 'l') { word[9]++; usleep(100000); printf("%s\n", word); }
    word[10] += 64;
    while (word[10] != 'd') { word[10]++; usleep(100000); printf("%s\n", word); }
}

🚀 How to Run

1. Clone the Repository:

   git clone https://github.com/B3TA-BLOCKER/hello-world.git
   cd hello-world

2. Install gcc (if not already installed):

   • Ubuntu/Debian:

     sudo apt update
     sudo apt install gcc

   • MacOS:

     xcode-select --install

   • Windows: Download and install MinGW.

3. Compile the Code:

   gcc -o hello hello_world.c

4. Run the Program:

   ./hello

Sit back and enjoy the animation! 🎉

🎨 Customization

Feel free to tweak the usleep values to speed up or slow down the animation. You can also modify the target message by adjusting the loops and target characters.

📦 Requirements

• A C compiler (e.g., gcc)
• A terminal to run the compiled program
