I have a few people arguing with me on the differences. I thought fgetc reads character by character of a file. I thought fscanf reads the whole file. Is that corrrect? Can someone elaborate on what I forgot? Re: fscanf vs fgetc 11 Years Ago by deceptikon > Is that corrrect? Not at all. Have you checked a C reference manual? The only similarities `fgetc` and `fscanf` have is they read input from a stream, and fscanf can simulate `fgetc`. The people you were arguing with, what were their points? Perhaps we can clear up any errors on both sides if you elaborate. Re: fscanf vs fgetc 11 Years Ago by COKEDUDE My understanding of fgetc is it reads character by character of a file. They think fscanf can also read character by character of a file. I do not think that is correct. I think fscanf is used for reading an entire file. I may not be explaing that with the correct terminology but I have used it for reading an entire file before. fscanf utilisation 11 Years Ago by bogoreh …("database.txt","r"); for(ctr=0;fscanf(fp,"%s %s %s %s %s %s", eli…[ctr].bid,eli[ctr].date1,eli[ctr].date2)!=EOF;ctr++) { fscanf(fp,"%s %s %s %s %s %s", eli…
