How to Compile and Run C program Using GCC on Ubuntu 24.04 LTS (Linux)

**Title: How to Compile and Run C Program Using GCC on Ubuntu 24.04 LTS (Linux) | Step-by-Step Guide**

**Description:**

In this video, we'll show you how to compile and run a C program using the GCC compiler on Ubuntu 24.04 LTS (Linux). Whether you’re a beginner or a seasoned developer, compiling C programs in a Linux environment like Ubuntu is an essential skill. The GNU Compiler Collection (GCC) is one of the most widely used compilers for C, and we’ll walk you through the entire process, from installation to execution, on the latest Ubuntu 24.04 LTS release.

**What You’ll Learn:**

- **Installing GCC on Ubuntu 24.04 LTS:** If GCC isn’t installed on your system yet, don’t worry! We’ll start by showing you how to install the GCC compiler via the terminal. You’ll learn the commands needed to install the `build-essential` package, which includes the GCC compiler and essential tools for C development.

- **Writing a Simple C Program:** Before compiling, we’ll demonstrate how to create a simple C program using a text editor like `nano`, `vim`, or any other editor of your choice. We’ll guide you through writing a basic "Hello, World!" program and saving it in a `.c` file format.

- **Compiling the C Program with GCC:** Once you have written your C program, we’ll show you how to compile it using the GCC compiler. You’ll learn the syntax of the `gcc` command, how to specify output file names, and how to compile multiple files if needed. We’ll also explain common compilation flags like `-o` (for specifying the output filename) and `-Wall` (for displaying warnings).

- **Running the Compiled C Program:** After compiling your C code into an executable, we’ll guide you through running the program directly from the terminal. You’ll see how easy it is to execute your compiled C programs in Linux by simply typing the output filename.

- **Debugging Common Issues:** We’ll cover how to troubleshoot common errors during the compilation and running process, such as syntax errors, missing libraries, and incorrect file paths.

**Key Steps:**

1. **Install GCC on Ubuntu:**
Open your terminal and run:
```bash
sudo apt update
sudo apt install build-essential
```
This will install GCC and other essential development tools.

2. **Create a C Program:**
Create a simple C file:
```bash
nano hello.c
```
Add the following code:
```c
#include stdio.h

int main() {
printf("Hello, World!\n");
return 0;
}
```
Save and exit the text editor.

3. **Compile the C Program:**
Run the following command to compile the file:
```bash
gcc hello.c -o hello
```
This will create an executable named `hello`.

4. **Run the Program:**
To run the program, use the following command:
```bash
./hello
```

**Key Features:**

- **Complete Setup Guide:** We guide you through each step, from installing GCC to running your first C program on Ubuntu 24.04 LTS.

- **Beginner-Friendly:** This tutorial is easy to follow for beginners, even if you have never compiled a C program before.

- **Efficient Workflow:** Learn the essentials of writing, compiling, and executing C programs in a streamlined manner using the terminal.
