從比較的矢量的WCHAR字符串與其他指定的字符串WCHAR

Question

@pmr：看看下面的代碼

@singeroftheall：我有兩件事的問題。插入和搜索。我認爲搜索部分已經完成。現在我怎樣才能將我的Mac地址插入向量中？ 我的地址保存在varable m_device_info.Adress.rgBytes [];見下文。

wprintf(L"\t\tAddress: %02x:%02x:%02x:%02x:%02x:%02x\r\n", m_device_info.Address.rgBytes[0], m_device_info.Address.rgBytes[1], m_device_info.Address.rgBytes[2], m_device_info.Address.rgBytes[3], m_device_info.Address.rgBytes[4], m_device_info.Address.rgBytes[5]); 

可以混合語言C和C++嗎？導致矢量輸出在C++？

============================================== ==================================== 我寫了一個代碼，顯示所有可用的藍牙設備。我只想將可用設備的所有MAC地址（類型：wchar）保存在向量列表中。之後，我想要搜索指定的wchar，如果它在矢量列表中。

我不是c/C++的專業程序員，只是需要這個來比較一下演示，看看我的想法是否有效。如果有人能幫助我，我會非常高興和開心。我也搜索谷歌和寫在其他常見問題，但沒有找到一個很好的解決方案，可以幫助我。

首先：在string中的人物類型wchar，但char的不是。你可能需要一個vector<wstring>。

#include <algorithm> 
#include <vector> 
#include <string> 
using namespace std; 

vector<wstring> vec; 
// insert something 
vec.push_back(wstring("my_string")); 

// search something 
vector<wstring>::iterator it = std::find(vec.begin(), vec.end(), wstring("needle")); 
if(it != vec.end()) { 
    cout << "Found it" << '\n'; 
} else { 
    cout << "Not found" << '\n'; 
}
