typedef语法错误 [英] typedef Syntax Error
问题描述
我在typedef上遇到语法错误代码行在这里。任何
想法为什么？ TIA
struct CSTYPE
{//城市/州记录
string csKey; //城市/州钥匙
string csCity; // City
string csState; //国家代码
};
typedef map< string，CSTYPECSINFO; //< ===错误在这里
extern CSINFO cityStInfo;
extern map< string，CSTYPE> :: iterator csIter;
extern CSTYPE workCS;
I''m getting a syntax error on the "typedef" code line here. Any
thoughts on why? TIA
struct CSTYPE
{ // City/State Record
string csKey; // City/State "Key"
string csCity; // City
string csState; // State Code
};
typedef map<string, CSTYPECSINFO; // <=== error here
extern CSINFO cityStInfo;
extern map<string, CSTYPE>::iterator csIter;
extern CSTYPE workCS;

1.你是#include< mapand< string>？
2. map和string live in std :: namespace
3.您是否愿意描述具体的错误？
1. did you #include <mapand <string>?
2. map and string live in the std:: namespace
3. Would you care to describe the specific error?

他的编译器可能不允许使用不完整的
类型作为模板参数，即使在typedef中也是如此，' 'CSTYPE''
当时不完整...

请在通过电子邮件回复时删除资金''A'
我没有回复最热门的回复，请不要问
It''s possible that his compiler does not allow the use of incomplete
types as template arguments, even in typedefs, and ''CSTYPE'' is
incomplete at that point...

以下似乎与GCC 4一样有效。
#include< map>
#include< string>
使用std :: map;
使用std :: string;
// TODO：展开" cs"更有意义的事情。
命名空间cs {
// TODO：给这个类型一个更有意义的名字。
结构类型{
string key;
string city;
string state;
};
typedef map< string，typeinfo;
}
#include< iostream>
int main（）{
cs :: info info;
info [" hello"]。key =" world" ;;
info [" foo"]。key =" bar";
std :: cout<< info [" hello"]。key<< ''\ n'';
std :: cout<< info [" foo"]。key<< ''\ n'';
}
....
The following appears to work as expected w/GCC 4.
#include <map>
#include <string>
using std::map;
using std::string;
// TODO: Expand "cs" to something more meaningful.
namespace cs {
// TODO: Give this type a more meaningful name.
struct type {
string key;
string city;
string state;
};
typedef map<string, typeinfo;
}
#include <iostream>
int main() {
cs::info info;
info["hello"].key = "world";
info["foo"].key = "bar";
std::cout << info["hello"].key << ''\n'';
std::cout << info["foo"].key << ''\n'';
}
