函数库Bug

Question

#include <string>
#include <iostream>
using namespace std;
#include <Windows.h>

int main(){
	wstring str1 = L"新";
	wstring str2 = L"更";
	cout << lstrcmp(str1.c_str(), str2.c_str()) << endl;
	if (str1 < str2)cout << -1 << endl;
	cout << endl;

	wstring str3 = L"e55h";
	wstring str4 = L"evgv";
	cout << lstrcmp(str3.c_str(), str4.c_str()) << endl;
	if (str3 < str4)cout << -1 << endl;
}

输出：

1

-1

-1

-1

如果lstrcmp能正确判断，将会输出-1

2L说的没错 新uni是65B0 而更是66F4 新在更前面

Answer 3

如果这样就对了，所以lstrcmp是比较发音，string 是比较值
