C++项目中出现错误LNK2005

Error LNK2005 in C++ project

由于错误LNK2005 ，我的功能出现问题

void createNetwork(Link **linkTable, Router **router, Computer **computer) {
router = new Router*[5];
linkTable = new Link*[11];
computer = new Computer*[6];
//---------------------------------------------------------------
router[0] = NULL;
//---------------------------------------------------------------
router[1] = new Router(1);
router[1]->link = new Link*[4];
   ....

错误：

我试着把它修好，但没用。有人能告诉我该怎么修吗？Thx:）

如果要在标头中定义函数，请将其标记为inline，以允许在包含标头的每个翻译单元中进行定义。

或者，将定义移动到源文件中，使其只定义一次。
