Write a C program to create a binary ppm file with $1000$ by $1000$ pixels. It uses five input

colors to draw a picture. See sample runs. The input colors can be: red, green, blue,

yellow, orange, cyan, magenta, ocean, violet. The corners of the central part should use

the $249$th and the $250$th row, and the $749$th and $750$th column.

Restrictions on the file format:

$$ no comment line after the file type specification

$$ width $($number of columns$)$ and height $($number of rows$)$ formatted in ASCII

decimal in the second line, separated by a space

$$ maximal value of color components given in the third line

Requirements on parallel execution:

$$ The original process should write the header information into the image file.

$$ Use fork$()$ to create $10$ child processes. Each child process writes $100$ rows of data

into the image file, and can use up to $350$KB of memory.

$$ The original process does not work on the pixels. It creates the $10$ child processes

to do so$.$ To avoid having multiple child processes simultaneously accessing the

image file, the parent process simply waits for one child process to terminate

before creating the next.

Other requirements:

$$ You are not allowed to use standard I$/$O library functions or graphics related

libraries.

$$ The command line arguments include the following in order: $($i$)$ the name of the

image file; $($ii$)$ color for center; $($iii$)$ color for top$-$left corner; $($iv$)$ color for topright corner; $($v$)$ color for bottom$-$left corner; $($vi$)$ color for bottom$-$right corner. $$
