LRU Page Replacement Algorithm in C2 min read

In this tutorial, we will look at C program for LRU Page Replacement Algorithm.

Least Recently Used (LRU) Page Replacement algorithm

It is an algorithm whose concept is based on the pages used in an instruction. The pages that are vigorously utilized in past instruction are probably going to be utilized intensely in the next instruction and the pages with used less are likely to be used less in the future. When a new page refereed is not present in the memory, a page fault occurs.

Whenever a page fault occurs, the page that is least used is removed from the memory frames.

Let us see an implementation of lru page replacement in c.
