1.用visual c++的时候可以运行，用dev的时候排除重复数字的方程不工作
2.在我赢的时候，debug显示 Run-Time Check Failure #3 - The variable 'colLetter' is being used without being initialized.，而且N是一个？
You won!
Winning Numbers: B-11 I-23 ?0 G-48 O-67 Continue to play? (N for No):
3。只能输出我赢，没办法输出电脑赢
4。怎么把最当中的那个0改成free，是个int的二维数组
5。 计算输赢的公式好像错了，但不知道是哪里
谢谢
