PAGING PROGRAM IN C++

THIS IS PAGING CODING IN C++ THAT HELP IN CODING AS WELL AS IN LEARNING

PAGING N C++:
#include<iostream>
using namespace std
int main()
{
int MAX=100;
int page[MAX],i,n,f,ps,off,pno;
system("cls")
cout<<"\nEnter the no of pages in memory"<<endl;
cin>>n;
cout<<"\nEnter page size"<<endl;
cin>>ps;
cout<<"\nEnter no of frames"<<endl;
cin>>f;
for(i=0;i<n;i++)
page[i]=-1;
cout<<"\nEnter the page table\n"<<endl;
cout<<"Enter frame no as -1 if that page is not present in any frame"<<endl;
cout<<"\npageno\tframeno\n-------\t-------";
for(i=0;i<n;i++)
{
cout<<"\n\n this \t\t"<<i<<endl;
cin>>page[i];
}
cout<<"\n\nEnter the logical address(i.e,page no & offset):";
cin>>pno>>off;
if(page[pno]==-1)
cout<<"\n\nThe required page is not available in any of frames"<<endl;
else
cout<<"\n\nPhysical address(i.e,frame no & offset):"<<page[pno]<<off);
return 1;
system("pause");
