Question

vc6.0使用map容器发生错误

代码如下:
#include<iostream>
#include<string>
#include<map>
using namespace std;
int main()
{
map<string, int> ma;
string word;
while(cin >> word)
++ma[word];
for(map<string,int>::iterator ix = ma.begin(); ix != ma.end(); ++ix)
cout << (*ix).first << " " << (*ix).second << endl;
return 0;
}

出现21 error(s), 0 warning(s):

等等......请问这是怎么回事?编译器问题?改怎么办?

Answer 1

是楼主的编译器有问题！！！！

我用c++ 6.0 运行完全正确！！！！

如下：

aaaa
bbbb
cccc
ssss
dddd
^Z
^Z
aaaa 1
bbbb 1
cccc 1
dddd 1
ssss 1
Press any key to continue

Answer 2

VC6对标准C++，特别是STL的支持很不好

建议用DEV C++ 或VS2005
