C++二進位檔案中讀寫bitset

標籤：

這個比較簡單，直接上代碼：

bitset< 32> *b = new bitset<32>(255);bitset< 32> *c = new bitset<32>(0);ofstream out("I:\\test.dat",ios::binary);out.write((char *)b,4);out.close();ifstream in("I:\\test.dat", ios::binary);for (int i = 0; i < c[0].size();){    char temp = 0;    in.read(&temp, sizeof(char));    for (int j = 0; j < 8; j++)    {        bool flag = (bool)((temp >> j) & 1);        if (flag)            c[0].set(i + j);    }    i = i + 8;}cout << "位元影像讀取就位" << endl;cout << c[0] << endl;in.close();delete b;delete c;
