Help with " expected specifier-qualifier-list before 'public' "

Guys i tried many things but i can't resolve this error,
here is the code:

RawImage.h

Code:

struct RawImage
{
    public: // <- error
        int get_width() const { return width; }
        int get_height() const { return height; }
        byte[] get_raw() const { return raw; }
        void set_width(int w) { width = w; }
        void set_heigth(int h) { heigth = h; }
        void set_raw(byte[] r) { raw = r; }
        RawImage(int w, int h, byte[] r) : width(w), heigth(h), raw(r) { }
        RawImage() { }
    private:
        int width;
        int heigth;
        byte[] raw;
};

error :

Code:

/RawImage.h|6|error: expected specifier-qualifier-list before ‘public’|

I'm having the same error in another struct, but i think that isn't necessary put the other struct here since the errors are the same, and resolving this i will be able to resolve the other.
Many Thanks.
ps : English isn't my native language, so sorry for any mistake.

> public: // <- error
Well if you're compiling this as C, then stop using C++ syntax in a struct.

> byte[] get_raw() const ....
And also stop using Java syntax for declaring byte arrays as well.

What a shame, sorry about that, I'm new with c, but now I'm getting a new error:

Code:

RawImage.h|6|error: expected ‘:’, ‘,’, ‘;’, ‘}’ or ‘__attribute__’ before ‘{’ token|

the new code:

Code:

struct RawImage
{ //error
        int get_width() { return width; }
        int get_height() { return height; }
        byte *get_raw() { return raw; }
        void set_width(int w) { width = w; }
        void set_heigth(int h) { heigth = h; }
        void set_raw(byte *r) { raw = r; }
        RawImage(int w, int h, byte *r) : width(w), heigth(h), raw(r) { }
        RawImage() { }
    private:
        int width;
        int heigth;
        byte *raw;
};

Thanks.

Thanks.

• Get rid of "private:". It should be obvious that this, along with the already-removed "public:", shouldn't be here.
• "byte" is most likely not a type, unless you've type-def'd it. Use "unsigned char" or simply "char".
• You can't define functions inside a struct. You *might* want to use a function pointer > Function Pointers in C and C++ - Cprogramming.com but still, you can't define the function there.

Then stop posting what is ostensibly still C++ code. If you're so new you aren't aware that the concept of public and private don't exist, then you're not ready for structs yet. Sit down with some good C tutorials. Start at the beginning, with Hello World and the like. Learn C as a totally new language, nothing like C++, except for one letter in the name.

Tutorials to get you started:
C Tutorial - Learn C - Cprogramming.com,
http://kldp.org/files/c+in+21+days.pdf

Google will turn up scads more. Read through all the lessons and work all the practice problems.

In C, structs contain data. The data may be basic types (int, float, double), pointers, enumerated types, and other structs.

Your code has the structs having member functions. Such things are not permitted in C.

The code being posted is more likely to be based on Java, not C++ (that byte[] return type and argument in the first post is certainly not C++). Either way, the code is using multiple features that are not part of C.

The real mistake the OP is making is to try to learn one programming language by analogy from another. C has more in common with C++ than with Java, but I would never recommend trying to learn C by analogy from C++ (or vice versa). Trying to learn C by analogy from Java is wasting time.

Just to nitipick: looks more like C++ because of the way "public" and "private" are deployed; in java they are used like any other modifier, and doing that would be a basic syntax error ("illegal start of type"). Also, while const is a reserved word in java, it has no use (it is not really a keyword, using it in any context is just an error; the real equivalent is "final").

Ok guys, thanks for the help. I'm compiling in C because I was getting an error using the GTK+ library and C++ but maybe you can help me. I will create another topic since the problem now is different and then i will edit this post with the link.
Thanks

So here is the link for the other topic, i think this topic can be closed. But I'm new here and I don't know how to do this.
GTK+ C++ compiler and signal handlers.
Thanks again, I'm loving this forum
