关于 “输入一个以long为单位的距离，然后转成码（一long等于200码）” 的问题

不明白哪里出了问题，肛入坑

#include <iostream>
int transfrom (int);
int main()

{
    using namespace std;
    int long;
    cout << "Enter the ma in long : ";
    cin >> long;
    int ma = transfrom (long);
    cout << long << "long =";
    cout << ma << "ma" << endl;
    return 0;

}

int transfrom (int sts)
{

    return 220 * sts;
    
}

只是书中将stone转化pounds的代码，我模仿了一下一直报错，不知道哪里的问题

#include <iostream>
int stonetolb(int);
int main()
{
    using namespace std;
    int stone;
    cout << "Enter the weight in stone: ";
    cin >> stone;
    int pounds = stonetolb (stone);
    cout << stone << "stone = ";
    cout << pounds << "pounds." << endl;
    return 0;
}

int stonetolb(int sts)
{
    return 14 * sts;
}

long是C++关键字，不能拿来作为变量名，改成别的名字。
