that file is saved from the same script id like to load it. the problem is that there are three different classes, and each employee is part of one of those, but how can i know which class is he one i need to create to load that employee? The classes i have are: Manager, Engineer and Researcher. the first 2 are managers, the 3rd and 4th are Engineers and the 5th and 6th are Researchers. I tryed to identify which was the class needed by searching for the words "Meeting", "Knows" or "PhD" but got problems with that.
How can i do this? please help! if you want i can post the full code..it isnt long.

I think you get a line and then split it into the key and value. Then you look at what kind of keys you got for each entry,

oh ya its a good idea...something like this for example?:

Code:

---

string s;
getline(inFile, s);
int length = s.length();
string key = s.substr(0,13);
string value = s.substr(13, length-13);

---

and how can i know which is the class of the object i have to create(Manager, Engineer or Researcher)?

Read in all the keys (not just one!) and then look to see which of your "special" keys was included. (Your belief that the key is the first thirteen characters, rather than up to the first = sign, is confusing to me.)

Alternately, yell at the people writing the file out to include a key like Type = Manager.

tabstop i know i have to read in all the keys, that was just an example, and how can i do a code to read until the '='? something like this? this is just for the second line(First name):

Code:

---

string key;
getline(inFile,key,'=');
string value;
getline(inFile,value);

---

Will the value have at the first char a blank space? if so, how can i prevent that?

The key will end with a blank space, and the value will start with a blank space. You can use erase to get rid of characters inside a string. It wouldn't be a bad idea, just in case, to check first/last letter before erasing it to make sure it's a space.

ok thatnk you very much, and by the way, what does fflush() does? cause i had a problem with getline but i solved using it like this:

Code:

---

        fflush(stdin);
        cout << "School: ";
        getline(cin, mSchool);
        cout << "Thesis: ";
        getline(cin,mThesis);

---

if i dont add fflush it would skip the first getline...is this a wrong way of solving it? or is it fine? i dont know, cause i dont know what fflush does...

If you want to 'flush' the input stream, then use cin.ignore(), not fflush(stdin)
http://www.cplusplus.com/reference/i...am/ignore.html

> if i dont add fflush it would skip the first getline
That's because you're mixing input methods
For example
cin >> myInt; // leaves a trailing \n for getline() to eat immediately

Which, if you follow with a getline call results in the first getline being 'skipped'

> is this a wrong way of solving it?
Using .ignore() would be far better.

Thank you salem. Ill use .ignore() now ;)
