Fifo page replacement algorithm in c++
WebDec 20, 2024 · Hence, we will write the program of Optimal Page Replacement Algorithm in C++, although, it’s very similar to C. INPUT: The first line is the number of frames (n). The second line is the number of processes (m). The third line is an array of processes (p [m]). OUTPUT: Print the matrix for processes and frames. Also, print the hit and page fault. WebJan 21, 2024 · Programming Code for Optimal Page Replacement in C++. We will look at two different methods –. Method 1: Uses array to store Frame items. Method 2: Uses Vector to store frame items. Method 1. Method 2. Using Array to store Frame items. #include using namespace std; // This function checks if current strea item (key) …

WebHere, 'P' is used to represent pages. 'N' is the number of pages. 'C' is the Capacity. Implementation of FIFO Page Replacement Algorithm Using A Programming Language. Step 1. Start to traverse the pages. Step 2. If the memory has less pages than capacity; else goes to step 6.Step 3. ==Push== the pages in set one at a time until the size of set does … WebThe FIFO algorithm uses the principle that the block in the set which has been in the block for the longest time is replaced. FIFO is easily implemented as a round robin or criteria buffer technique. The data structure used for implementation is a queue. Assume that the number of cache pages is three. Let the request to this cache be shown ...
