无法将参数2从'const char [5]'转换为'LPCWSTR'

Question

int main() {

    string url;
    int a;
    int b = 0;
    cout << "Enter url: ";
    cin >> url;
    cout << "how many times do you want to open the url?: ";
    cin >> a;
    while (b<a)
    {
        ShellExecute(NULL, "open", url.c_str, NULL, NULL, SW_SHOWNORMAL); 
        b++
        }
        cin >> a;
        }

//给我带来麻烦的那部分 是“开放部分说它不能转换// itShellExecuteW（HWND，LPCWSTR，LPCWSTR，LPCWSTR，LPCWSTR，INT）”：不能将//参数2从'const char [5]'转换为'LPCWSTR'

Answer 1

调用ShellExecuteA而不是ShellExecute，Windows API有大量的宏来决定ANSI和Unicode版本
