VS2008: Error C2679 help?

[deltatux]

Hey guys,

I'm trying to open a file, however, I'm running into problems:

TDirectory.cpp

code:

#include <iostream> using namespace std; #include <fstream> #include "TDirectory.h" bool Listing::loadFileData(FILE* fp){         fseek(fp, 0, SEEK_SET);         ifstream in(fp);         while (in) {                 in >> givenName >> surname >> address >> telephone;         } }

TDirectory.h

code:

struct Listing {         char fname[16], lname[16], addr[16], phnum[16]; public:         bool loadFileData(FILE *fp);     const char* givenName() const;     const char* surname() const;     const char* address() const;     const char* telephone() const; }; struct Directory {         FILE *fp;         int records;         struct Listing *listings; public:         bool loadFileData(const char* filename);         void display() const;         void close(); };

Error:

Quote:

error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'overloaded-function' (or there is no acceptable conversion)

If I can't get this fixed, I might be forced to mix C with C++ and it'll go ugly...

Many thanks,

Your input statement:

code:

in >> givenName >> surname >> address >> telephone;

is trying to read strings into your getter functions. That's probably not what you meant.

[md]

Furthermore, character strings are a C construct. When using C++ you should use std::string wherever possible.

[deltatux]

So should I just read them directly into chars in the struct?

it worked on my other software but am having a tough time with this one =s...

No, just use the >> operator and change the types of your string variables to be std::string .

[deltatux]

How do I do that?

While you're at it, mixing C file handling and C++ iostreams is a good way to give yourself a headache.

Think about what the error is telling you:

code:

error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'overloaded-function' (or there is no acceptable conversion)

For the binary operator >> it's getting a right-hand operator of type overloaded-function.

What does this mean?

Unfortunately, at my college, they came up with this brilliant idea by mixing C with C++ since we did C last semester, so they thought that by mixing C in C++ it'll make the transition easier =S... I think they shouldn't have done that.

It's very confusing.

and I don't understand the error at all >.<"
