WebOct 11, 2024 · The 'optimal page replacement algorithm' is not practical because it cannot predict whether the page it is going to remove will not be used in the future. Maybe it removes a page and then immediately after an iteration we will again need that removed page in a frame. ... Now, let us see an example in C++ language to understand how this ... WebDec 20, 2024 · When a page needs to be replaced, the operating system chooses the page which is least frequently used for the replacement with the incoming page. We will use C++ to write this algorithm due to the standard template library support. Hence, we will write the program of LFU Page Replacement Algorithm in C++, although, it’s very similar to C.
