C :: Program To Create 2D Array For Each Row

What I am trying to do is to have the program create 2D array that for each row, no two numbers are the same and only consists numbers between 1-9. The array lists out every possible combinations. Supposely I do not know the number of possible combinations, I had it keep adding new rows until there are no more possiblities left.

The problem with my code is when I print out the completed array, it gives out really, really large numbers. But when I print the array from inside the first loop, it gives correct values. I do not know exactly what happened.

Code:
#include <stdio.h>
int main(void) {
int double_digit[1][2];

int a = 1;
int b = 1;

[Code] ....
