hi,
can someone pls tell me how i can open a file that contains numeric data (like, millions of numbers) and do mathematical operations on them? if i am not wrong, the basic skeleton of what i have to do is to open the file (surprisingly, some are 'plain text files', though they contain entirely numbers), place these numbers into arrays, then perform the operations on each element, then output the new arrays into the output file.
are there any particular chapters in a c book that i can refer to? i cannot read the whole book as i don have the time.
