Can you create a simple "Hello World" program i the programming language C with instructions on how to compile and run the program?
Here is the simple "Hello World" program in C:
```#include <stdio.h>

int main()
{
    printf("Hello World!\n");
    return 0;
}```
To compile and run the program, follow these steps:
1. Save the above code to a file with a .c extension, for example hello_world.c.
2. Open a terminal or command prompt and navigate to the directory where the file is saved.
3. Compile the program by running the following command:
```gcc -o hello_world hello_world.c```
4. Run the compiled program by typing the following command:
```./hello_world```
5. You should see the output Hello World! displayed in the terminal.

Note: The above instructions are for a Unix-based system. If you are using Windows, you may need to use a different compiler or set up a development environment.
