林得到以下錯誤，我不知道它是什麼意思：錯誤錯誤LNK2019

Question

我有一些麻煩。程序工作，然後當我分裂成每個功能我得到這些錯誤：

錯誤1錯誤LNK2019：無法解析的外部符號「int __cdecl calcAVE（int * const，int）」（？calcAVE @@ YAHQAHH @ Z）引用在函數_main c：\ Users \ Joshua \ documents \ visual studio 2013 \ Projects \ ConsoleApplication10 \ ConsoleApplication10 \ Source.obj ConsoleApplication10

請幫助，謝謝。

#include <iostream> 
using namespace std; 

void getUserInput(int [], int&); 
int calcAVE(int [], int); 
void outPute(int [], int, int); 

int main() 
{ 
    int theAverage = 0; 
    int ct = 0; 
    const int MAX_SIZE = 100; 

    int theArray[MAX_SIZE]; 

    getUserInput(theArray, ct); 
    theAverage = calcAVE(theArray, ct); 
    outPute(theArray, ct, theAverage); 
    return 0; 
} 

void getUserInput(int theArray[], int& ct)

    int quit = 0; 
    int theNums = 0;

     cin >> theNums;enter code here 

     if (theNums == quit)

    for (i = 0; i < ct; i++) 
    {

     average = total/ct;

你的函數原型：

int calcAVE(int [], int); 

你的功能：

int calcAve(int theArray[], int ct) 

C++是大小寫敏感的。因此，calcAVE is not the same as calcAve。你的輸出功能有同樣的問題。
