6. Write a Sample C Program

Create a simple C program to test your installation. Open a text editor like nano:

$ nano hello.c

Add the following code:

#include <stdio.h>

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

Save and exit the editor.

7. Compile the C Program

Use Clang to compile your C program:

$ clang hello.c -o hello

This command generates an executable named hello.

8. Run the Program

Execute your compiled program:

$ ./hello
