To use this program: 1. Compile it with a C compiler: 
1
2
   gcc -o italian_flag italian_flag.c
2. Run and redirect output to a .bmp file: 
1
2
   ./italian_flag > italian_flag.bmp
This will create a 300x200 pixel Italian flag bitmap image. The image is written directly to stdout in a format that can be saved as a .bmp file. Key points about the program: - Follows the BMP file format specification - Uses little-endian encoding - Creates a 24-bit bitmap - Divides the flag into three equal vertical stripes (green, white, red) - Uses standard colors for the Italian flag You can adjust the width and height constants to change the flag's size.

To use this program: 1. Compile it with a C compiler, e.g.: 
1
2
   gcc italian_flag.c -o italian_flag
2. Run the program and redirect output to a .bmp file: 
1
2
   ./italian_flag > italian_flag.bmp
This program will generate a 300x200 pixel BMP image of the Italian flag (green, white, and red vertical stripes). Key points: - Uses standard BMP file format - Writes header information directly to stdout - Creates pixel data representing Italian flag colors - Uses BGR color order as required by BMP format - Divides flag into three equal vertical sections You can adjust the width and height in the `main()` function to change the flag's dimensions.

# Generate the BMP file
./italian_flag > italian_flag.bmp

# Or directly pipe to an image viewer or file
./italian_flag | display  # ImageMagick
# or
./italian_flag > italian_flag.bmp
Notes: - The program generates a 300x200 pixel BMP image - Colors are in BGR format (BMP's native color order) - The flag is divided into three equal vertical stripes: green, white, red - Outputs directly to stdout in BMP format - Handles BMP row padding for proper image alignment - Uses little-endian encoding for multi-byte values The resulting image will be a simple representation of the Italian flag with vertical stripes of equal width.

To use this program: 1. Compile it with a C compiler: 
1
gcc -o italian_flag italian_flag.c
2. Run and redirect output to a .bmp file: 
1
./italian_flag > italian_flag.bmp
This will generate a 300x200 pixel bitmap image of the Italian flag with vertical green, white, and red stripes. Key points about the implementation: - Uses standard BMP file format - Writes header and pixel data directly to stdout - Colors are in BGR format (Blue, Green, Red) - Creates a simple vertical tricolor flag - Handles little-endian integer encoding You can modify the width, height, or color values as needed.

To use this program: 1. Compile it: `gcc flag.c -o flag` 2. Run it and redirect output to a .bmp file: `./flag > italian_flag.bmp` The program creates a 300x200 pixel flag with vertical stripes of green, white, and red, matching the Italian flag's design. A few key points about the implementation: - Uses standard BMP file format - Writes header and pixel data directly to stdout - Uses 24-bit color depth - Divides width into three equal vertical sections - Uses approximate colors for the flag sections You can modify dimensions, colors, or aspect ratio as needed.
