C++里怎样用map将枚举类转换到string类

#include<stdio.h>
#include<stdlib.h>
#include <string>
#include <map>
#include <iostream>
using namespace std;
int main (void)
{
enum Name{AMY,JOHN,JOY};
map<Name, string> nameMap;
nameMap[AMY] = "AMY";
nameMap[JOHN] = "JOHN";
nameMap[JOY] = "JOY";Name salesname=JOHN;
string nameStr = nameMap[salesname];
cout<<nameStr<<endl;}这里的error怎样解决？

#include<stdio.h>
#include<stdlib.h>
#include <string>
#include <map>
#include <iostream>
using namespace std;typedef enum {
AMY,
JOHN,
JOY
}Name;int main (void)
{map<Name, string> nameMap;
nameMap[AMY] = "AMY";
nameMap[JOHN] = "JOHN";
nameMap[JOY] = "JOY";Name salesname=JOHN;
string nameStr = nameMap[salesname];
cout<<nameStr<<endl;} 会出百现很多警告，不度要管他，直问接运答行就可以了，专我用得是属vc++6.0

#include<stdio.h> #include<stdlib.h> #include <string> #include <map> #include <iostream> using namespace std;

typedef enum { amy, john, joy }name;

int main (void) {

map<name, string> namemap; namemap[amy] = "amy"; namemap[john] = "john"; namemap[joy] = "joy";

name salesname=john; string namestr = namemap[salesname]; cout<<namestr<<endl;

}

会出现很多警告，不要管他，直接运行就可以了，我用得是vc++6.0

将百map<Name, string> nameMap;改成度知map<int, string> nameMap; 改后道为专：属#include<stdio.h> #include<stdlib.h> #include <string> #include <map> #include <iostream> using namespace std; int main () { enum Name{AMY,JOHN,JOY}; map<int, string> nameMap; nameMap[AMY] = "AMY"; nameMap[JOHN] = "JOHN"; nameMap[JOY] = "JOY"; Name salesname=JOHN; string nameStr = nameMap[salesname]; cout<<nameStr<<endl; return 0;}
