More Help

Ok, I spent 2 days on this problem...for my RPG, when the user chooses a profession, nothing happens, I just get this error:
C:\Program Files\Microsoft Visual Studio\My Projects\RPG2k\main.cpp(54) : error C2679: binary '<' : no operator defined which takes a right-hand operand of type 'const int' (or there is no acceptable conversion)

here's what I do for the prof choice:

Code:

---

void begin()
{
        user.proftype == 0;
      system("cls");
        pcol();
        cout << "What is your name?\n";
        cin  >> user.name;
        cout << "Thank you "<<user.name<<".  Please choose a class:\n\n";
        cout << "Please Choose Your Class Type:\n"
                        "1] Thief\n"
                        "2] Cleric\n"
                        "3] Mage\n"
                        "4] Warrior\n";
        cin  >> user.proftype;
        while(user.proftype < 1 ||  user.proftype > 4) // <-- error line
{
  //uses switch statments which are not posted in code here
}
}

I am just wondering if someone knows the answer to this. I have tried for 2 days trying to fix it. Or if anyone knows of a better way of doing this.

user.proftype == 0;

isn't it suppose to be 1 equal cause 2 equals is comparing and 1 is assigning a value, but thats the only mistake i see in your code.

Nope, if I do that, I get this error:

Code:

---

C:\Program Files\Microsoft Visual Studio\My Projects\RPG\main.cpp(42) : error C2593: 'operator =' is ambiguous
C:\Program Files\Microsoft Visual Studio\My Projects\RPG\main.cpp(54) : error C2679: binary '<' : no operator defined which takes a right-hand operand of type 'const int' (or there is no acceptable conversion)

Of what type is user.proftype
Is it an int or another class type?

it's of a struct....here's the struct for it:

Code:

---

struct PLAYER
{
        apstring name;
        apstring proftype;
};
PLAYER user;

---

*I have apstring.h included

Now hear dis

I'm not sure 'bout apstring, but if it's a class then then problem
is that the '=' operator was not overloaded to accept an int.

Try making proftype an int rather than an apstring:

Code:

---

struct PLAYER
{
        apstring name;
        int proftype;
};
PLAYER user;

void begin()
{
        user.proftype = 0;
      system("cls");
        pcol();
        cout << "What is your name?\n";
        cin  >> user.name;
        cout << "Thank you "<<user.name<<".  Please choose a class:\n\n";
        cout << "Please Choose Your Class Type:\n"
                        "1] Thief\n"
                        "2] Cleric\n"
                        "3] Mage\n"
                        "4] Warrior\n";
        cin  >> user.proftype;
        while(user.proftype < 1 &&  user.proftype > 4) // <-- error line
}

that one screws up my loading and saving functions.....

Well then look up the methods of apstring if it is a class.
There should be one that returns the string/buffer. Try assigning
to the returned pointer.

OR

Lookup how the '=' operator is overloaded and what it accepts.

If it can accepet char* then you do this:

Code:

---

user.proftype = "";

---

and if the [] operator was overloaded too, then you should do this

Code:

---

while(user.proftype[0] < 1 &&  user.proftype[0] > 4)

This was already done yesterday, but no info.

The fist one (user.proftype ="";...never thought of that one, thanks....the second one I'll try first...thank you

you might have to declare the struct as

Code:

---


external struct PLAYER
{
  apstring name;
  int proftype;
} user;

//forget about doing PLAYER user...that's a waste of time

---

Basically if the struct is declared in .h file and is going to be used in another file I think you might have to delcare the file as an external struct. I'm not positive, though, and I'm probably wrong because I only skimmed over the thread.:)

TechWins: You ain't wrong, but I did fix it. I had to take out the while, and the counter (user.proftype == 0). But thanks anyways.
