How to read in a text file of tab-separated integers in C?

Question

I have a file of simply tab-separated integers (a .txt file) and I wish to read them in with just C, line by line. So, say each line has 5 integers. How can I accomplish this?

Answer 1

I'd do something like this:

int storedVals[MAX_STORED_VALS];
int bf;
int ii=0;

while (!feof(fp) && ii

fscanf automatically does white space trimming. So as long as there's a space in your scan string, it'll get rid of zero or more \t (tabs) and \n (newlines) to find the next integer. Of course, this doesn't do much by way of error correction.
