Hi everybody! i need somebody's help. I located 2d array into vector, but I don't how to "std::cout" it. Please, help.
Oh, and 1 more thing. If somebody know better way to locate 2d array into vector, I'll apreciate your help.
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 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63
#include <iostream>
#include <cstdlib>
#include <vector>
#define COL 8
#define ROW 8
using namespace std;
void del(int **);
int main()
{
int arr[COl][ROW];
vector<int > mV;
for (int i=0; i<COL; i++)
{
for (int j=0; j<ROW; j++)
arr[i][j]=rand()%100;
}
int **p, **s, *h;
p=new int *[COL];
for (int i=0; i<COL; i++)
p[i]=new int [ROW];
s=new int *[COL];
for (int i=0; i<COL; i++)
s[i]=new int [ROW];
for (int i=0; i<COL; i++)
{
for (int j=0; j<ROW; j++)
p[i][j]=arr[i][j];
}
del(s);
int q, w;
for (q=0, s=p; q<COL; q++, s++)
{
for (w=0, h=*s; w<ROW; w++, h++)
mV.push_back(*h);
}
for (q=0, s=p; q>COL; q++, s++)
{
for (w=0, h=*s; w<ROW; w++, h++)
cout<<mV[*h]<<" " ;
cout<<endl;
}
del(p);
return 0;
}
void del(int **p)
{
for (int i=0; i<COL; i++)
delete [] p[i];
delete [] p;
}

in the same way you've populated the vector you could write a method to print it out in the same way.

I have tried to do it in way, like you said, but I failed. My compiler gave me a segmentation fault.

No need in example any more. I have done it by myself. But I have a new probelm. arr[COL][ROW]
and vector content are different. Why???
