I want to code a program so as to be able to read the contents(which is just numbers) of a file.This is what i have done:

--------------------------------------------------
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <fstream>
using namespace std;
int f,o,u1,u,w1,w2,w3,w4,w5,w6,w7,w8,w9,w10,w11,w12,count,v1,v2,v,l1[20],l2[20],l3[20],mx1[4],my1[4],mz1[4],m,z,q,y,int1,int2,int3,i1,j1,q1,q2,q3,q4,ux,uy,uz,rx,ry,rz,mx ,mz ,my ,txx, txy, txz  ,tyx, tyy, tyz , tzx, tzy, tzz ,hz ,hy ,hx ,Jxx ,Jyy ,Jzz ,Jxy, Jxz ,Jyx ,Jyz ,Jzx ,Jzy;
int a[3][3];
unsigned long c[3][1];
int d1[100][100];
int d2[100][100];
int d3[100][100];
int h[3][1];
int b[3][1];
int f1,f2,i,l,j,k,t,A=2,B=2,n;  
int temp1,temp2,temp3;    

int main()

{
    ifstream  ifs ("inp.txt");
    ifstream in_stream1;
      ifstream in_stream2;
      ifstream in_stream3;
      ofstream out_stream1;
      ofstream out_stream2;
      ofstream out_stream3;
      FILE *stream1,*stream4;
    stream1 = fopen( "infile2.txt", "r+" );
    stream4  = fopen( "outfile1.txt", "r+" );
      in_stream1.open("infile2.txt");
    if (in_stream1.fail())
    {
        cout << "Input file opening failed.\n";
        exit(0);
    }
      
      out_stream1.open("outfile1.txt");
    if (out_stream1.fail())
    {
        cout << "Input file opening failed.\n";
        exit(0);
    }

for (f = 0;f <= 11; f++)
{
in_stream1 >> c[f][0];
cout << c[f][0];
}
out_stream1 << endl;
cout << endl;

return(0);       
        
        
    in_stream1.close();
      out_stream1.close();
    }
 
--------------------------------------------------

and this is the file's contents:

3
6
5
8
6
7
4
5
2
3
1
9

with these specific numbers the program can only read six or seven characters!!But with other numbers e.g:

2
5
4
3
5
4
1
5
2
7
2
4

it can read all of them.What do you think the problem is?
I am using VC++ 6.0

You need to simplify this a great deal.

> unsigned long c[3][1];

You have a 2D array here dimensioned 3 x 1

>for (f = 0;f <= 11; f++)
>{
>in_stream1 >> c[f][0];
>cout << c[f][0];
>}

When f is > 2, this should go kaboom.
