使用C++的地图出现有关问题
使用C++的map出现问题
具体是这样的，我要写一个词法分析器，用到了C++中的map数据结构，在map中插入map<Point ,char> OriginalCharAndPosition;类型的数据，其中Point是我自己定义的类，表示该字符在原
文中的位置。可运行时就出了个断言错，就是在插入数据时出现了问题，是在插入第二行数据时出现的错，该错误是由，Point中重载的<号引起的。具体情况见代码
主函数：
#include "DealCharacter.h"
int main()
{
DealCharacter dealcharacter;
/*map<Point*,char> OriginalCharAndPosition;
vector<int> dealCharPosition;*/
//OriginalCharAndPosition,dealCharPosition
dealcharacter.pro_process();
dealcharacter.coutchar();
return 0;
