c++数组打印十六进制？

Question

希望大家帮帮忙。当我尝试向该数组添加值时，即 1、2、3、4，它会打印为十六进制数吗？我怎样才能实际打印非十六进制数组？谢谢

int main()
{
    int gr1;
    int gr2;
    int gr3;
    int gr4;
    int addup[4]={gr1, gr2, gr3, gr4};
    cout << "Please enter the first grade";
    cin >> gr1;
    cout << "Please enter the second grade";
    cin >> gr2;
    cout << "Please enter the third grade";
    cin >> gr3;
    cout << "Please enter the fourth grade";
    cin >> gr4;

        cout << addup;

}

您正在向数组中添加未初始化的变量。

int main()
{
    int gr1;
    int gr2;
    int gr3;
    int gr4;
    cout << "Please enter the first grade";
    cin >> gr1;
    cout << "Please enter the second grade";
    cin >> gr2;
    cout << "Please enter the third grade";
    cin >> gr3;
    cout << "Please enter the fourth grade";
    cin >> gr4;

    int addup[4]={gr1, gr2, gr3, gr4};

    for ( int i = 0; i < 4; i++ )
        cout << addup[i];

}
