C :: Two Stumbling Blocks - Determine Size Of Rows To Create In Program

Working on an assignment and I've hit TWO stumbling blocks. I now have to take the first line from a .txt file and use that number to determine the size of rows to create in my program. I am using fscanf but the program hangs. How can I read in this number, store it and use it in a for loop?

The second issue is after reading this number I have to print each number in the .txt file under a different column. (Note that it skips a line after reading the row count.) The .txt file is set up as follows:

9 1 3 6 4 7 8 8 6 1

The output should look sort of like:

Number ​1 3 6 4 7 8 8 6 1

Here's my attempt:
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <math.h>

typedef struct{
int number;
