output = div(27, 4);
cout << "Quotient part of (27/ 4) = " << output.quot << endl;
cout << "Remainder part of (27/4) = " << output.rem << endl;
output = div(27, 3);
cout << "Quotient part of (27/ 3) = " << output.quot << endl;
cout << "Remainder part of (27/3) = " << output.rem << endl;
return(0);
}输出结果
Quotient part of (27/ 4) = 6 Remainder part of (27/4) = 3 Quotient part of (27/ 3) = 9 Remainder part of (27/3) = 0
