# Issue

*This Content is from Stack Overflow. Question asked by Elliot *

I am trying to write a program that reads in integers from a file and creates bitwise table. The first line in the file is the numbers of rows (unknown). Each row is two integers (X, Y) that I will use in bitwise operations and print out. Each row will have 6 columns (X, Y, X & Y, X | Y, X ^ Y, ~X). I am stuck at the f for loop to print out the numbers that come from those operations. This is what I have so far:

```
//Variables
//output of first line of input file is
//number of rows for problem A
int N;
in >> N;
//output of second to N lines of input file
unsigned short X, Y;
in >> X >> Y;
//2D array for bitwise table...?
unsigned short ** bitwiseTable1;
//allocate rows only
bitwiseTable1 = new unsigned short * [N];
//allocating the columns
for (int r = 0; r <= N; r++)
bitwiseTable1[r] = new unsigned short [6];
//Traverse the array
for (int r = 0; r <= N; r++)
for (int c = 0; c < 7; c++)
{
//need to read in X,Y from file ? stuck here!
cout << r << c << r & c << r | c << r ^ c << ~r
cout << X << set(5) << Y << set(6) << (X & Y)
<< set(6) << (X | Y) << set(5) << (X ^ Y)
<< set(6) << (unsigned short)(~X) << end;
`enter code here`}
```

some of the code I changed to be able to post this so in is really in file, end is end line, set is set width

Thank you for your help!
