操作系统实验-页面地址重定位

页面地址重定位#include <iostream>#include <iomanip>#define PagetableLength 64using namespace std;int PageTable[PagetableLength] = {0};//前提：地址是从0开始的int main(){    int LogicalAddress = 0;    int PageNum = 0;    int w = 0;    int i = 0;    int num = 0;    int f;    int PageSize;    char flag;    cout << "请输入页号长度;" << endl;    cin >> num;    cout << "请输入页面大小：" << endl;    cin >> PageSize;    cout << "请依次输入块号；" << endl;    for(i = 0; i < num; i++ )    {        cin >> PageTable[i];    }    cout << "系统页号对应块号情况;\n";    for (i = 0; i < num; i++)    {        cout << setw(2) << i << "-->" << setw(2) << PageTable[i];        if(i % 8 == 7)            cout << endl;    }    while(f)    {    cout << endl << "请输入逻辑地址;\n";        cin >> LogicalAddress;    PageNum = LogicalAddress / PageSize;    w = LogicalAddress % PageSize;//求页内偏移地址    if(PageNum >= PagetableLength)//判断是否越界    {        cout << "本次访问的地址已超出进程的地址空间，错误！；\n";        return -1;    }    cout << "对应的物理地址为;" << endl << PageTable[PageNum] * PageSize + w << endl;    cout << "你还想继续请求分配吗？是请按Y/y,否按其他键" << endl;           cin >> flag;            if(flag == 'Y' || flag == 'y')                f = 1;            else                break;    }        return 0;}
