Question

很简单的c++入门问题。这代码有什么错误？

#include <iostream>
int zhuanma(int);
int main()
{
using namespace std;
cout << "how many LANG?" << endl;
int LANG;
cin >> LANG;
int MA;
MA = zhuanma(LANG);
cout << LANG " LANGs = " << MA << "MAs";
cin.get();
return 0;
}
int zhuanma(int n)
{
return 220 * n;
}
有一个error.可是没写出哪里的错误。希望告诉我要怎么改正

Answer 1

cout << LANG " LANGs = " << MA << "MAs";
少了一个<<
cout << LANG << " LANGs = " << MA << "MAs";

Answer 2

没输出，死循环
