How would I create this function using C?

e. Declare a variable, data type integer, to store the page faults,
initialize to 0 (i.e., pageFaults)
f.
Declare a one-dimensional array, data type integer, to store the
memory frame a page is allocated to (i.e., allocation), size is
parameter FRAMES
g. Declare a variable, data type integer, to store page hits (i.e.,
present)
h. Declare a variable, data type integer, to store number of pages
(i.e., pages) initialized to the number of page requests
Initialize the allocation array by calling function memset,
passing arguments
i.
i. Array allocation
ii. -1 (i.e., INVALID)
iii. sizeof(allocation)
j. Using a looping construct, iterate through the number of pages
i. Set variable present equal to 0
ii. Using a looping construct, iterate through the number
of FRAMES
1. If the current page request is equal to the
current frame allocation
a. Increment the present variable by 1
b. Decrement the pageFaults variable by
1
iii. Increment the pageFaults variable by 1
iv.
If the number of page faults (i.e., pageFaults) is less
than or equal to the FRAMES AND variable present
is equal to 0
1. Update the allocation array for the current page
by setting it equal to the current pageRequest
v. Else if, variable present is equal to 0
1. Replace the page at the front of the queue by
updating the allocation array using index
(pageFaults - 1) % FRAMES equal to the
current pageRequest
vi. Call function displayPages passing arguments
1. the current pageRequest
2. allocation array
vii. Display to the console the total number of page faults
