Question

我需要帮助原型。
我需要帮助来电。
我需要有关函数头的帮助。

我不知道这个网站想要我添加多少细节，但代码说明了一点，我在前三个项目上遇到了问题，但由于某种原因，该网站需要更多上下文？

#include <iostream>
using namespace std;

void fillArray(int salesSheet[][COLSIZE], int rowSize);
// I dont know how to create prototype for 2d array
int main()
{
    const int ROWSIZE = 5, COLSIZE = 6;
    int salesSheet[ROWSIZE][COLSIZE], a, rowSize;

    fillArray(a[][COLSIZE], int rowSize);
    // I don't know where I messed this up 
    // I messed up the caller too, help?
    return 0;
}
void fillArray(int salesSheet[][COLSIZE], int rowSize)
{
    int r, c;
    cout <<"Enter sales report for each quarter, for your branch." << endl;
    for (c = 0; c < COLSIZE; c++) 
    {
        for (r = 0; r < rowSize; r++)
            cout << "\nBranch " << c+1 << " quarterly sales figures:"
        cin >> salesSheet[r][c];
    }
}

Answer 1

#include <iostream>
#include <malloc.h>
using namespace std;
const int ROWSIZE = 5, COLSIZE = 6;
void fillArray(int*** salesSheet, int rowSize, int colSize);

int main()
{
    int** salesSheet = (int**)malloc(COLSIZE*sizeof(int*));
    int* arr = (int*)malloc(ROWSIZE*COLSIZE*sizeof(int));

    for(int i = 0; i < COLSIZE; i++)
      salesSheet[i] = arr+i;

    fillArray(&salesSheet, ROWSIZE, COLSIZE);
    free(salesSheet);
    free(arr);
    return 0;
}
void fillArray(int*** salesSheet, int rowSize, int colSize)
{
    int r, c;
    cout <<"Enter sales report for each quarter, for your branch." << endl;
    for (c = 0; c < COLSIZE; c++) 
    {

        for (r = 0; r < rowSize; r++){
            cout << "\nBranch " << c+1 << " quarterly sales figures:";

            cin >> salesSheet[0][r][c];
        }
    }
}

Answer 2

#include <iostream>
using namespace std;

const int ROWSIZE = 5, COLSIZE = 6;

void fillArray(int salesSheet[][COLSIZE]);

int main()
{
int salesSheet[ROWSIZE][COLSIZE];

fillArray(salesSheet);

return 0;
}
void fillArray(int salesSheet[][COLSIZE])
{
int r, c;
cout <<"Enter the sales report for each quarter, in you branches column."    
<<  endl;
for (c = 0; c < COLSIZE; c++) 
    {
    for (r = 0; r < ROWSIZE; r++)
        {
            cout << "\nBranch " << c+1 << " quarterly sales figures:" ;
            cin >> salesSheet[r][c];    
        }
    }
}

C ++ 2d数组......在原型上丢失了，并且在任何地方都没有看到
