2D array

Eyad (98)
How can I output 2D array (8*8) but in order?

0 1 2 3 4 5 6 7
8 9 10 11 12 13 14 15
16 17 18 19 20 21 22 23
24 25 26 27 28 29 30 31
32 33 34 45 46 47 48 49
50 51 52 53 54 55 56 57
58 59 60 61 62 63 64 64
65 66 67 68 69 70 71 72

#include <iostream>

void setarray(int ma[8][8],int size,int jsize)
{
  for (int i=0;i<size;i++)
    for (int j=0;j<jsize;j++)
      ma[i][j] = i+j;
}

void printarray(int ma[8][8],int dim1, int dim2)
{
  for (int i=0;i<dim1;i++)
  {
    for (int j=0;j<dim2;j++)
		cout<<ma[i][j]<<"  ";
    cout<<endl;
  }
}

int main()
{
	  int multiarray[8][8];

	  setarray(multiarray,8,8);
	  printarray(multiarray,8,8);

	system("pause");
}


I cannot find out a solution, help please.

// 2D Array.cpp : main project file.

#include <iostream>

using namespace std;

void setarray(int ma[8][8],int size,int jsize)
{
	for (int i=0;i<size;i++)
		for (int j=0;j<jsize;j++)
			ma[i][j] = i+j;
}

void printarray(int ma[8][8],int dim1, int dim2)

	int multiarray[8][8];

	setarray(multiarray,8,8);

If I have understood what you want then you can use the following code to fill the array


1
2
3
4
5
6
7
8
9
 
int n = 0;

for ( int i=0; i < 8; i++ )
{
	for ( int j=0; j < 8; j++, n = ( n == 34 ) ? 45 : n + 1 )
	{
		ma[i][j] = n;
	}
}


The output is

0 1 2 3 4 5 6 7
8 9 10 11 12 13 14 15
16 17 18 19 20 21 22 23
24 25 26 27 28 29 30 31
32 33 34 45 46 47 48 49
50 51 52 53 54 55 56 57
58 59 60 61 62 63 64 65
66 67 68 69 70 71 72 73


I am sorry. I have not seen that 64 is duplicated in your output

58 59 60 61 62 63 64 64
65 66 67 68 69 70 71 72


Is it a typo?
