Multi-dimensional matrix to file

[Dr01d]

Hello,

I am trying to put on a file a multi-dimensional matrix
something like the code below.

I can write and read a vector ou a uni-dimensional matrix to file but i've been struggling to do a multidimensional matrix.

May be i'm using a bad aproach, but i'm a beginner and all the help and advice is always welcome.

Thanks in advance.


#include <iostream>
#include <fstream>

using namespace std;

main()
{
char matriz[5][5];
for(int a=0;a<5;a++){
for(int b=0;a<5;b++)
matriz[a][b]='a';
}
ofstream fo("c:\\file.txt");
for(int a=0;a<5;a++){
for(int b=0;a<5;b++)
fo << matriz[a][b];
}
fo.close();
ifstream fi("c:\\file.txt");
char ch;
while(fi.get(ch))
cout.put(ch);
fi.close();
system("pause");
}

Watch your loop indices.

  for (int a=0; a < 5; a++)
  for (int b=0; b < 5; b++)
    ...

Also, please use [code] [/code] tags.

Hope this helps.
