printing to an array

i have a text file that contains numbers and i am reading them in line by line, this is not a problem

but the problems come when i try to get these numbers and put each number in the array, for some reason it just seems to take the first character (either a 0 or a -) and it printts out it's ASCII equivialant and i don't want this

any ideas on how to remedy this ??

here is the code so far

any help will be appreciated :D

cheers

That's because you are reading a character, and you're assigning it as a character:

Code:

---

numbers[i] = (double)*nums;

---

This says "Give me the decimal value of whatever character I read, and use that as a float.

Quzah.

the file that i am reading in contains a long double on every line

so how would i remedy it so that it enters these into the array ?

thankyou for your speedy response :D

Assuming your compiler / libraries provide something like atof, you can just use that. Otherwise, you'll need to use something like sscanf to read it into a variable.

so if i were to use sscanf()

i would do something like this ?/

Code:

---


sscanf(nums, numbers[i], float);

---

sorry for all the questions but this is beginning to bug me :p

atof doesn't seem to work properly

here is a copy of the txt file if it helps ??

No, it'd be something like this:

sscanf( nums, "%f", &numbers[i] );

sscanf works just like scanf, except you specify where you scan from as the first argument.

Or better still, use strtod(). The FAQ shows some examples of getting numbers.

i have done that now, but it still doesn't seem to work, all it prints out is 1000 lines of 0.000000000000000

so it seems that it isn't working with those values at all

any idea where it is going wrong ??

Cheers

ok

here is the C file and text file that it is reading in

and here is the txt file :D

thanks for your help :D

i see what you say, and i have implemented that now,

but it still prints out 1000 lines of 0.000000000000000

it is driving me mad !!

Thank you ever so much,it is finally working :D

and i have learnt a lot from this to

sorry about all the questions


Thanks to all that helped :D
