当我们必须从选项中选择一个时，这是在 C++ 中做出选择的正确方法吗？

is this is right way to make choice in c++ while we have to choose one from option?

c++
project

case 1:
    cout<<"what is the name of our country. \n A. india \t\t B. africa \n C.australia \t\t D.america\n";
    if(toupper(getchar()) == 'A' ) // **is this is right way?**
       {

        cout<<"correct. \n you win 0000\n"; count++;
        getch();
        break;
    }
    else

否，但这有效

#include <iostream>

using namespace std;

int main()
{
    char a;
cout<<"what is the name of our country. \n A. india \t\t B. africa \n C.australia \t\t D.america\n";
cin>>a;
if (a== 'A') cout<<"correct. \n you win 0000\n";
if (a== 'B') cout<<"Welcome to Africa\n";


    return 0;
}
