Question

This is my code on Q&A game on Visual C++

             if (this->answer->Text == "2"){
                 this->question->Text = "2+2?";
             }
             else if (this->answer->Text == "4"){
                 this->question->Text = "3+3?";
             }
             else if (this->answer->Text == "6"){
                 this->question->Text = "4+4?";
             }
             else if (this->answer->Text == "8"){
                 this->question->Text = "Finished!";
             }
             else {
                 MessageBox::Show("Wrong!!");
             }

Is there any to shorten this code? consider using arrays?

I am not a Windows programmer, don’t know what the type of your
this->question->Text is, you didn’t tell us, but if it is std::string or something which can be converted to char *, then this should work:

std::string t = this->answer->Text;
this->question->Text = t == "2" ? "2+2?"
                     : t == "4" ? "3+3?"
                     : t == "6" ? "4+4?"
                     : t == "8" ? "Finished"
                     : "";
if (this->question->Text = "") MessageBox::Show("Wrong!!");
