Say I'm reading an input file, and I have a line which is just five integers separated by spaces like:

4 12 1

And if want to store these in an array I'd use something like

fscanf(fileName, "%d %d %d", &arr[0], &arr[1], &arr[2]);

(I'm new to C so please correct the above if that's not quite right)

However, this gets very clunky if I had even more integers on a line and wanted to store those in an array like

4 12 1 132 66 47 77 32

Is there a way to use a loop to read and store the first integer on the line, second integer, and so on?

Are you familiar with `fgets()` for reading a _line_ of input? – chux - Reinstate Monica Oct 01 '18 at 02:13
@chux im not super familiar with that function, how would I use that in this case? – user7446944 Oct 02 '18 at 00:46
