c++定义变量出错如何解决

Question

我刚学c++,写了下面这几行，结果出错了

#include<iostream>
using namespace std;

int main()
{
    //好家伙，这是一行注释！
    int a = 10;
    //下面两个是常量
    const int b = 5;
    //define后头不加分号
    #define Cc 20
    cout << "this should be 10" << a << endl;
    cout << "this isn't changeable" << b << endl;
    cout << "this is another constant value" << Cc <<endl;
    return 0;
} 

我在树莓派上用vscode直接f5跑的，报错如下:

Breakpoint 1, main () at /home/freeman/Desktop/test.cpp:14
14 int a = 10;
Loaded '/lib/aarch64-linux-gnu/libstdc++.so.6'. Symbols loaded.

[Inferior 1 (process 20718) exited normally]
The program '/home/freeman/Desktop/test' has exited with code 0 (0x00000000).
我该如何解决？我哪里出了错？

正常运行完后退出了吧？要不return上面加system("pause");
