错误LNK2019:未解析的外部符号“void __cdecl battingAverage(int(* const)[3],double(* const)[3],int,int)”(?battingAverage @@ YAXQAY02HQAY02NHH @ Z)引用在函数_main

它显然必须处理main函数中的函数battingAverage调用,我在这里搜索了这个错误,试图将c ++编译器选项更改为'Console',但它没有帮助。请帮助大家,我相信这是一个小问题,但我很累,试图解决它。

答案 0 :(得分:4)

您的声明:

void battingAverage(int[][numscores],double[][numscores],int,int);

您的定义:

void battingAverage(int bats[][numscores],double [],int numplayers,int  numscores)

正如您所看到的,第二个参数存在差异 - double[][numscores] vs double[]。所以你实际上是在定义一个完全不同的功能。
