C Programming Tutorial # 41 - fscanf() - feof() - Reading From A File - Part 1 [HD]

In this tutorial we learn how to read from a file. We also learn how to detect that we have reached the end of file and that there is no more data to read.

This tutorial is part of the following series:

[TmacRockets]

why did you decide to go with the name "joe" instead of something more traditional like Ravikkumar or Sivanthanan

[jarrettmaier]

you didnt explain feof even tho its in the title

[AutoRijeka]

This is great episode of tutorial. It is very easy to understand how everything works.
I am just woried it is one of last episodes :)
Please make more videos, they are priceless for a someone like me, who want to learn by self.

@Asmik20112011 This is more of a convention. All the variable names represent the contents of the variables except arrays whose names represent the address of the first element of the array. Now fscanf() always needs an address as the argument or parameter. So if you are passing an integer you have to use & to pass the address of the integer, but if you are passing an array or a string then all you need to do is to pass the name of the array and that would serve as the address.

Thank you, it was a great help for me :)

[Asmik]

Please, explain, why the second argument of fscanf () should be an address of the variable "score" and not just the name of this variable?? (At the same time, to read the string "Joe" into "name" you don't give its address, you give just the variable name..)

[tunamusic]

why do we need sign " & " before variable score ?

i have yet to see a tutorial that explains how to use [ ^ ] \n etc etc to real a more complicated file

[Asmik]

@Learnorama Thank you so much for the answer. And your C Prog tutorials are really a great job. Thanks.

it seems correct when ive seen it being done in the video .. but i did the same exact thing and it said "could not open the file ."

[immygran]

how do i read 1 line at a time and pause at each line for question & answer
program and print to the screen in c++

if(x ==1)textview01.setText(" Alabama pop.4, 661, 900")
if(x ==2)textview01.setText(" answer 1819 Montgomery pop.202, 124")
if(x ==3)textview01.setText(" Alaska pop.686.293")
if(x ==4)textview01.setText(" answer 1959 Juneau pop.30, 988")
if(x ==5)textview01.setText(" Arizona pop.6.500.180")
if(x ==6)textview01.setText(" answer 1912 Phoenix pop.1, 601, 587")

[vigneshwarankannan]

[lindawisebear]

Great video but didn't explain feof which was the reason I wanted to watch it; would recommend changing the title of the video. Otherwise, a good video!

[CarlNathanII]

why is it in c++? the title says c, or is there no difference to the syntax? thank you

[aman]

great vids, when i make this program its only prints one word, in the text if theres a space it wont print it, how do i do this??, so its prints out like this

dog cat tim bill fine ect

[dipankar]

but how to print a whole line from file using fscanf().

[JossinJax]

Good stuff, but why doesn't C require you to add an ampersand symbol in front of "name" like you needed for "score"?

[tadm]

how do I use a loop to read characters on a text instead of doing it one by one?
