如何在Linux下的C++文件使用GDB调试

25         cout << "------------------------------------" << endl;

27     }
28 }
29 int main()

31     int arr[10] = { 0 };
32     for (int i = 0; i < 10; ++i)
33         arr[i] = (i + 1) * 10;
34     show(arr, 10);

/*在Xshell中编译，在Linux环境下*/
g++ -o main main.cpp
/*可以使用更简单的，直接g++ main.cpp，这样生成的文件就是a.out*/
