Question

为什么下面的代码没有给出结果以及如何获得结果？

每当我运行代码时，它首先要求两队参赛者的名字，然后它显示菜单，如果我们选择任何一个选项，它再次询问击球手名称不是根据程序设计。我对代码和问题的研究是，我认为缓冲存储器已满，但我不知道如何释放它，任何帮助都是有益的。谢谢

Answer 1

这是非常错误的：

for(int j=0;j++;j<12)

应该是：

for(int j=0; j < 11; j++)

Answer 2

您还错过了案例4声明中的选项：

case 4: {cout<<"Enter number of wickets to be updated:";
         cin >>upwicket;
         cout<<endl;
         wicketstaken[k]+=upwicket;
         break;
         }
default:cout<<"wroung choice";

如果没有中断，当用户选择选项4时，您还会看到输出错误选择。
