在C++收到此错误，"std：cin.std 中的'运算符>>不匹配"

#include <iostream>
int main()
{
using std::cout;
using std::endl;
using std::cin;
short width;
short legnth;
short height;
short volume;
volume = (legnth * width * height);
cout << "This program will determine the volume of a cube" << endl;
cout << "Enter the legnth of the cube: ";
cin >> legnth >> endl;
cout << "Enter the width of the cube: ";
cin >> width >> endl;
cout << "Enter the height of the cube: ";
cout << "Your volume is: " << volume;
cout << "Press any key to exit :)";
cin.get();
return 0;

我是C++的新手，在我的计算机编程基础课上，我们必须制作一些可以计算音量的东西，有人能帮我纠正这个错误吗？
