Visual Studio C++ 错误：函数已经有主体

Question

只是一个警告，我是 C++ 新手和缺乏经验，所以如果我的语法真的很糟糕或者我遗漏了一些明显的东西，请原谅我。我正在尝试制作一个允许我从其中打开其他程序（如游戏启动器）的程序。

我不想在代码中定义程序，这样我就可以在不重新编译的情况下更改它。我正在使用一个 Visual Studio 生成的 Windows 窗体头文件，我对它进行了一些调整和一个主 cpp 文件。当我去编译时，我得到一个ERR_MESSAGE 说我的函数已经有了主体。这是我的代码：

CPP 脚本MyForm.cpp：

#include "MyForm.h"
#include <iostream> // Debug (Remove once done)
#include <fstream> // File stream
#include <stdlib.h> // Execute files

using namespace std;
using namespace System;
using namespace System::Windows::Forms;

// Creating the virtual file arrays
char line1[];
char line2[];
char line3[];
char line4[];
char line5[];
char line6[];
char line7[];
char line8[];
char line9[];
char line10[];
char line11[];
char line12[];

namespace Loader {
    void loadProgram(int num) {
        char new_line[] = { '\n' };
        if (num == 1) {
            if (line2 != new_line) {
                system(line2);
            }
        }
        else if (num == 2) {
            if (line4 != new_line) {
                system(line4);
            }
        }
        else if (num == 3) {
            if (line6 != new_line) {
                system(line6);
            }
        }
        else if (num == 4) {
            if (line8 != new_line) {
                system(line8);
            }
        }
        else if (num == 5) {
            if (line10 != new_line) {
                system(line10);
            }
        }
        else if (num == 6) {
            if (line12 != new_line) {
                system(line12);
            }
        }
    }
}
