yeh i am doing them without them functions aswell.

how you managing to do the formatting [setw(4), etc] in the strings, i am assuming you made an array of strings?

This is my code for the formatting:

setw(20-data.surname.length()-data.firstname.length())

I outputted it after the firstname. They are from a struct called "data".

For the bonus, i used arrays of structs.

how did u guys made it all aligned

cos i don't think setw() works for strings

 

[redruM]

i know how to make it work using strings...but i have to try it out.

you use something like string streams.


thats a pretty cool method ND. mine is similar, but i stored my line of info as a string and stored that string in an array.
then i output each line of the array, for each grade.

did u use showpoint?

Heyas, new to board.

Anyway... I'm having a prob with assign3.

It was all working well, until i tried to make my own user defined function to print the stuff in the file, rather than have to write it 3 times....

I tried using prototype mode and all that, but it keeps saying my arrays from main are undefined.

Any ideas?

*EDIT*
Passed the values in 1 by 1 as normal strings and doubles rather than trying to pass over the whole array.... but everytime it clears the file when it passes through

 

[doe]

are you reopening the file and stuff each time? if so it might be trucating it.

move the arrays from main outside of any functions (ie make them global variables), or pass them as an argument.

 

[BigJim]

Ahhh thanks. Declared them outside main then just passed in the array position and it works now.

Yeah and I had it reopening and truncating file too.
inFile and outFile wouldnt work unless I did, until i moved em outside of main.

Cheers

ive tried using setprecision(2) but that simply truncates them all to integers (2 digits).

yeh like pb said, you gotta use showpoint. just chuck the following line in.
outFile.setf(ios::showpoint);

 

[redruM]

no worries...i cant get mine to work tho!!

the setw() isnt working with strings...aargh! have to use a loop which is going to output spaces....so fucked!

 

[...]

thats what i did

well, kinda

 

[redruM]

yay! completed it!!!

it is so inefficient tho...could have made it shorter, but cant be fucked now....at last i'll submit an assignment that was submitted at 22.5x

edit: yeh mine was like:

int e = 18-lastName.length()-firstName.length();
while ( e > 0)
                   {                                             
                    tempE << " ";                        
                    e--;
                   }

i used string streams, so it was like inputting a space, everytime it looped through, into the string.

 

[Wacky]

students.txt doesn't have a blank line at the end, so why would there be this problem?
EDIT: I was referring to the doubling up - I had this problem, then I downloaded the text from the site again and it worked fine
EDIT2: though regular_solution.exe seems to handle blank lines fine

 

[redruM]

yeh i had that problem too. it was coz of my while loop.

you just need to rearrange the inFile bit to the end, i think from memory.
