Dynamic Array Input

I'm currently working on a C code program for my research, which involves formation flying of spacecraft. All of my input comes from a text file and I'm trying to clean it up a little. I have to input adjacency matrix for all the spacecraft. AKA I need to input and store NxN matrix, where N in the number of spacecraft.

Ex: N = 2
Matrix =
0 1
1 0

Ex: N = 3
Matrix =
0 1 1
1 0 1
1 0 1

Currently I just have to list all the matrix components on a separate line (N=2 means the matrix is on 4 lines of the text file) and this is not very intuitive for larger numbers of spacecraft.

Is there a way to use sscanf dynamically to read in N number of integers on a line?

So for N = 2 or 3 it would do the equivalent of these

N = 2
Code:
sscanf(line, "%d %d", array[0][0], array[0][1])
sscanf(nextLine, "%d %d", array[1][0], array[1][1])
N = 3
Code:
sscanf(firstLine, "%d %d %d", array[0][0], array[0][1], array[0][2])
sscanf(seondLine, "%d %d %d", array[1][0], array[1][1], array[1][2])
sscanf(thirdLine, "%d %d %d", array[2][0], array[2][1], array[2][2])

 

While I'm sure there's some fancy foot-work that can be done with the "..." param, maybe you should consider using string tokenizers.
You can then feed the numbers in like:

Code:

num1,num2,num3,num4,num5,num6

Then loop through that, something like:

Code:

char* cPtr = strtok(inputStr, ",");
int i = 0;
int arr[50];
while (cPtr)
{
   arr[i] = atoi(cPtr);
   cPtr = strtok(NULL, ",");
   ++i;
}

Where "inputStr" is a char buffer you got via an input, like:

Code:

char* inputStr[100];
fscan("%s\0", inputStr);

Or something to that effect.
