if you dont mind can you write down the code ?

**~~userxbw~~** · 12-11-2017

I will give you this much because you also need to learn how to check your code to be sure it is doing what you want it to do, don't just assume it is working just because it looks right.

Code:

    /*
    string line;
    
    getline(myfile,line);
    outfile<<line<<endl;
    
    while(getline(myfile,line))
    {
        myvector.push_back(line);
    }
    */
    while (myfile >> firstName >> lastName >> rental >> balance)
    {
        myvector.push_back(firstName + " " + lastName + " " + rental + " " + balance);
    }
    for (auto i = myvector.begin(); i != myvector.end(); ++i)
    std::cout << *i << ' ';

it was not working so I fixed that.

Code:

// your code was only storing this

userx@slackwhere:~/bin
$ ./temp
starting
 anilo steve 0 0 userx@slackwhere:~/bin
$ ./temp

/ my fix gives you this to work with.

i have to submit the assignment and i just have like 2 hours please i would be so great if you can help me out

**ahmed_tannu** · 12-11-2017

i trying but i couldn't do it

**~~userxbw~~** · 12-11-2017

did you see post 18, and I'd have to whip out my google skills to even try to complete this in under two hours and I do not have a paypal account.

it is all in how you store your information, I do believe if I am correct that code I wrote turns it into one big string, then you'd have to split it again to get the last name in order to sort it.

**ahmed_tannu** · 12-11-2017

i dont know how im gonna finish it

**ahmed_tannu** · 12-11-2017

What if i give the whole code and you can just do the sorting code ?

**Salem** · 12-11-2017

It's time you just failed already.
If you put as much effort into study as you put into begging, you'd have this solved.

I got the whole code. how do you think I changed it?

**ahmed_tannu** · 12-11-2017

I did everything opening up from a file outputting it to other file but the thing i just dont get is the sorting and the first line of the input file which is the headers : Lastname, firstname, daysofrental, and balance

Here what i did so far

**~~userxbw~~** · 12-11-2017

here is what i did in my program I wrote awhile back and if you by chance figure out how to use it to your advantage, and the teacher asks you how did you figure that one out, well then that answer you give him or her is up to you isn't it?

Code:

//holds the path and file name
std::vector<std::string> dfile;


void sort_V()
{
    std::sort(opts.dfile.begin(), opts.dfile.end(), compareNoCase);
}
// Comparison; not case sensitive.
bool compareNoCase (std::string first, std::string second)
{
  unsigned long int  i = 0;
  while ((i < first.length()) && (i < second.length()))
  {
    if (tolower (first[i]) < tolower (second[i])) return true;
    else if (tolower (first[i]) > tolower (second[i])) return false;
    i++;
  }

  if (first.length() < second.length()) return true;
  else return false;
}

now you have to ask yourself, does that sort meet the requirements for the two sorts you have to pick from?

On your next assignment you get, learn how to google to ask how to's and work with small parts of your code until you get that to work first then move on to the next step in your program that needs to be done. Then if you have issues feel free to post in here or wherever for help and advice not will you do my homework I got two hours to turn it in. and not even show anything kind of work on your part in what you have been doing while waiting for an answer.
