Problem Updating An 2D Array

[atxc212]

Hi, my program is suppost to read a txt file with a 9x9 table of 1 digit number like this:
9 6 0 5 0 0 0 8 3
3 0 0 2 7 9 0 0 4
0 0 2 6 0 0 0 9 0
0 9 0 0 0 6 7 0 0
7 4 0 0 0 0 0 5 1
0 0 8 4 0 0 0 2 0
0 7 0 0 0 5 4 0 0
6 0 0 9 1 4 0 0 5
5 1 0 0 0 8 0 3 2

and then enter each value into a 2d array - rooms[9][9], which was declared in rooms.h:
'static int Game::rooms[9][9];'
and defined with the line in rooms.cpp:
'int Game::rooms[9][9];'
The definition of read() function was placed in rooms.cpp:

void Game::Read(string n)
{
    string Name = n;               
 
    ifstream I;            
    I.open(Name.c_str());
 
    while (!I.eof())
    {
        int Num;
        for (int i=0; i<r; i++)
        {
            for(int j=0; j<c; j++)
            {
                I >> Num;
                rooms[i][j] = Num;
            }
        }
    }
    I.close(); 
 

After it finished entering it will display the updated room array in console. For some reason the result shown became all '2's instead of a replica of the one in the txt file. The debugger showed Num is modified as it reads each number in the txt but for some reason it didn't get entered into the array slot? And I've looked for the value 2 in every identifier but it seems it came out of no where. I've tried puting 'rooms[i][j] = 1' instead of Num, and the new array shown indeed are all 1s. It seems it doesn't like rooms[][] to be set to a variable. What did I missed?

Hi,

I some how don't want to do any thing in C++. Dont know if the below C code is going to help you or not just give it a try..

#include<stdio.h>
void main()
{
int i,j,a[10][10],num;
FILE *f1;
f1 = fopen("c:/input.txt","r");
for(i=0;i<=9;i++)
for(j=0;j<=9;j++)
{
fscanf(f1,"%d",&num);
a[i][j]=num;
}
for(i=0;i<=9;i++)
{
for(j=0;j<=9;j++)
printf("%d ",a[i][j]);
printf("\n");
}
fclose(f1);
}

what say :)
