TYBSc CS OS Practical Slip Solutions 2025

Here’s a summary of the most common practical slips in SPPU TYBSc CS OS exams:

1. CPU Scheduling Algorithm

Problem: Simulate First Come First Serve (FCFS), Shortest Job Next (SJN), and Round Robin Scheduling.

Solution (FCFS in C):

#include <stdio.h>

int main() {

    int n, i, bt[20], wt[20], tat[20];

    printf("Enter number of processes: ");

    scanf("%d", &n);

    printf("Enter burst times: ");

    for (i = 0; i < n; i++)

        scanf("%d", &bt[i]);

    wt[0] = 0;

    for (i = 1; i < n; i++)

        wt[i] = wt[i - 1] + bt[i - 1];

    for (i = 0; i < n; i++)

        tat[i] = wt[i] + bt[i];

    printf("Process\tBurst Time\tWaiting Time\tTurnaround Time\n");

    for (i = 0; i < n; i++)

        printf("%d\t%d\t\t%d\t\t%d\n", i + 1, bt[i], wt[i], tat[i]);

    return 0;

}

3. Memory Management - Page Replacement Algorithms

Problem: Implement FIFO and LRU page replacement algorithms.

Solution (LRU in C++):

#include <iostream>
#include <vector>
#include <unordered_map>
using namespace std;
int lruPageReplacement(vector<int> pages, int capacity) {
unordered_map<int, int> page_map;
int page_faults = 0;
for (int i = 0; i < pages.size(); i++) {
if (page_map.size() < capacity) {
if (page_map.find(pages[i]) == page_map.end()) {
page_map[pages[i]] = i;
page_faults++;
}
} else {
if (page_map.find(pages[i]) == page_map.end()) {
int lru = INT_MAX, val;
for (auto it : page_map) {
if (it.second < lru) {
lru = it.second;
val = it.first;
}
}
page_map.erase(val);
page_map[pages[i]] = i;
page_faults++;
}
}
}
return page_faults;
}
