DON'T USE CHATGPT
Write a C program to simulate a memory management system that demonstrates
page faults and handles them using the clock algorithm for page replacement. Along
with the usereference bit, the dirty bit associated with each page should also be
considered.
Design
Simulate a memory of N pages using a fixedsize page table.
Input :
numframes: Number of available page slots frames
pagerequests: A string representing page requests Eg
Output:
Total page faults
Total page hits
Hit rate
Each page can be represented using a simple structure called struct page
defined as follows
struct page
uintt pagenumber;
bool referencebit;
bool dirtybit;
;
Memory frames can be represented using a simple array that holds the page
number and any necessary bits.
Algorithm :
Initialize all memory frames to be empty or some other value
Service each of the page requests from the list passed as input to the program.
Eg :
For each page request, check if the page is in memory check in the
frames array
If yes, it's a hit.
If no then use the clock algorithm to replace a page and update the
reference bit of the corresponding page struct page instance if
necessary.
After servicing all the requests, print out the total faults, total page hits and
hit rate.
