**Usage:** 1. Save this code in a file named `italian_flag.c`. 2. Compile the code using `gcc`: `gcc -o italian_flag italian_flag.c`. 3. Run the program: `./italian_flag > italian_flag.bmp`. 4. Open the generated `italian_flag.bmp` file in an image viewer to see the Italian flag. Note: This code generates a 24-bit BMP image with a resolution of 300x200 pixels. The flag is divided into three equal vertical stripes, with green on the left, white in the middle, and red on the right.
