Description
In this project, you will write a C program that prints
out the image width and height (in pixels) of a BMP file (source.bmp),
and then draws (i.e. inserts) two diagonal lines (in black, i.e. R=0,
G=0, and B=0) on a duplicate image (target.bmp). The command
line syntax is:
bmputil source.bmp target.bmp
The detailed description of BMP image format can be found here. You are allowed to use system calls only (no C I/O librabry!), except printf. Assume the number of bits per pixel is always 24. Note that you do NOT need to parse the entire BMP header, and your C program should be as concise as possible. Points will be deducted for unnecessarily long source code (and the penalty will be high).
Hint
You should be aware that BMP and C programs on various computers might have different data interpretations (e.g. signed vs. unsigned integers; little endian vs. big endian).
