获取当前路径

`

#include<iostream>
#include<windows.h>
#include<string>

int main()
{
char buf[100];
//int i = 100;
//LPWSTR 和char类型不兼容
//GetModuleFileName();
GetCurrentDirectoryA(100, buf); //得到当前工作路径

string a;
a.assign(buf);
cout << a << endl;

//这里的两个反斜杠必须加，因为这不是通过操作系统来进行目录切换的
//仅仅是简单的字符串拼接

/*strcat(buf, "\\..\\");
