C++ C++；并行阵列

在这个并行数组中，我看不到或弄不明白为什么要打印内存地址而不是输入的值。我要求C++诸神启发我，并给我指出一些关于这个问题的好教程，以便我能从中学习。代码如下

#include <iostream>
#include <ctime>
#include <cstdlib>
#include <iomanip>
#include <string>
#include <ios>

using namespace std;

// Assign a constant
const int rowSize = 6;
const int columnSize = 4;

void displayWelcome()
{
   cout << "\tCorporation X\n";
   cout << "Quartily Reports for the six Entities\n";
   cout << "Showing you the Highest Average out of the six\n";
   cout << endl;
}

// Assign Words in a row of 6
string* entitiesArray(string(entities)[rowSize])
{
    string entitiesName[rowSize] = {"East ","West ","Central ","Midwest"
      ,"South ","South East "};
    //string entitiesName;
    for(int i=0; i < rowSize; i++)
    {
        cout << entitiesName[i] << endl;
    }
    return entitiesName;
}

// Assign numbers to a 6x4
double* entriesArray(double(corpArray)[rowSize][columnSize])
{
    // Assign Random Numbers to the Array
    srand(time(0));
    double rowSum = 0.0, average = 0.0;

    for (int r = 0; r < rowSize; ++r)
    {
        rowSum = 0;
        for (int c = 0; c < columnSize; ++c)
        {
            corpArray[r][c] = rand() % 101;
            cout << setw(5) << left << corpArray[r][c] << " ";
            rowSum += corpArray[r][c];
            average = rowSum / 4;
        }
    cout << average;
    cout << endl;
    }
    return 0;
}

// Parallel Array  This is where is prints the Memory Address
void pArray(string &theEntitiesArray,double &theEntriesArray)
{
    string entity = &theEntitiesArray;
    double entry = &theEntriesArray;
    for(int row_index = 0; row_index < 6; row_index++)
    {
        cout << setw(10) << entity <<endl;
        for (int col_index = 0; col_index < 4; col_index++)
        {
            cout << setw(10) << entry << endl;
        }
    }
}

int main(int argc, const char * argv[])
{
    // Declare an Array & Variables
    double corpArray[rowSize][columnSize];
    string entities[rowSize];
    double* theEntriesArray;

    string* theEntitiesArray;
    char parallelArray;

    displayWelcome();
    theEntitiesArray = entitiesArray(entities);
    theEntriesArray = entriesArray(corpArray);
    pArray(*theEntitiesArray, *theEntriesArray);

    cout << endl;

 return 0;
}

cout@JSF在评论中击败了我，但是在
double entry=&theEntriesArray；
行中，您将
entriesarray
的地址分配给变量
entry
，而不是它引用的数值。将其更改为：

double entry = theEntriesArray;

您在初始化数组的函数中遇到了一些问题，请尝试阅读指针

void displayWelcome（）

可能与您的问题无关，但函数
entitiesArray
正在返回一个临时变量的地址，该变量具有未定义的行为。您应该使用
new
分配数组
entitiesName
，或者最好返回一个
std:：vector
，而不是一个数组。在这一行中
string entity=&theEntitiesArray；
您不想看到这一点&我不知道这一行对&（我不知道为什么它不是编译时错误）意味着什么，但无论它的意思是什么，都必须引起您想要修复的症状，并且您希望它的意思是，如果没有&
string entity=&theentiesarray；double entry=&theentriesaray；
Remove&从这些行中删除..否则您的代码对我有效..这是打印值。
