这是我第一次尝试 C++ STL。我正在尝试使用地图构建多维关联数组。例如:
typedef struct DA {
string read_mode;
string data_type;
void *pValue;
void *pVarMemLoc;
}DA;
int main()
{
map<string, map<string, map<string, map<string, map<string, DA*>>>>> DATA;
DATA["lvl1"]["stg1"]["flr1"]["dep1"]["rom1"] = new DA;
DATA["lvl1"]["stg1"]["flr1"]["dep1"]["rom2"] = new DA;
DATA["lvl1"]["stg1"]["flr1"]["dep1"]["rom3"] = new DA;
IEC["lvl1"]["stg1"]["flr1"]["dep1"]["rom1"]->read_mode = "file";
IEC["lvl1"]["stg1"]["flr1"]["dep1"]["rom2"]->read_mode = "poll";
IEC["lvl1"]["stg1"]["flr1"]["dep1"]["rom3"]->read_mode = "report";
return 0;
}
在 VS2005 中编译上面的代码时,我收到了 170 个 C4503 警告。
所有警告都是关于“超出修饰名称长度,名称被截断”。
该程序似乎运行良好。
有人愿意花一些时间向我解释导致这些警告的原因以及我该如何解决它们吗?提前致谢 :)
