Question

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：

1>device.obj : error LNK2005: "void __cdecl createNetwork(class Link * *,class Router      * *,class Computer * *)" (? createNetwork@@YAXPAPAVLink@@PAPAVRouter@@PAPAVComputer@@@Z) already defined in Computer.obj

我试图以某种方式修复它，但它没有工作。有人能告诉我该怎么做才能解决这个问题吗？谢谢：）

Answer 1

如果要在标题中定义函数，请将其标记为inline以允许每个翻译单元中包含标题的定义。

或者，将定义移动到源文件中，因此只定义一次。
