包含main()Visual Studio定义的两个文件? [英] Two files containing definition of main() Visual Studio?

问题描述

我已经在Visual Studio 2008专业版中创建了一个项目.

I have created a project in Visual Studio 2008 Professional Edition.

该项目为每个作业都包含一个.cpp文件，就像这样...

This project contains one .cpp file for each assignment like this...

[-]Source Files
   \
   |-- 233.cpp
   |-- test.cpp

每个文件都包含main()的定义.

操作:CTRL + F5

Action:CTRL+F5

Error   1   error LNK2005: _main already defined in 233.obj test.obj
Error   2   fatal error LNK1169: one or more multiply defined symbols found 

如何编译并查看每个文件的输出?

谢谢.

推荐答案

在一个项目中，不能有2个称为main()的函数.您应该做的是更改函数的名称，然后从一个新的main()函数(将其用作菜单)中调用它们.

You can't have 2 functions called main() in a single project. What you should do is change the names of the functions, and then call them from a new main() function which would function as a menu.

如果将它们做成单独的项目，则可以使用解决方案属性"->启动项目"来切换要运行的项目.

If you make them separate projects, you can switch which one to run with Solution Properties -> Startup Project.
