Install the additional manual pages for development:

apt-get install manpages-dev

After installation, check the installed version of GCC:

✅ That's it. GCC and related development tools are now installed on your Ubuntu 25.04 system.

Compiling a basic C or C++ program using GCC is straightforward. Let's create a simple Hello World C program.

Create a new file called hello.c:

nano hello.c

Add the following code:

// hello.c
#include <stdio.h>

int main() {
    printf("Hello, world!\n");
    return 0;
}

Save and exit the file.

Now compile the program and run it:

gcc -o hello hello.c
./hello

Output:

Hello, world!

🎉 Done! You have successfully installed GCC and compiled your first C program on Ubuntu 25.04.
