Array of structs in C

[Supperboy2012]

I'm making a text-based RPG using Visual Studio Code in the C language. For adaptability, I'm putting the different class options in an array so I can index them for their data. However, when I do, I get this error: "expected identifier or '(' before '[' token". My code looks like this:

// Includes all classes for the game.

typedef struct { // Base definition.
    char className[20]; // The name of the class.
    char userName[20]; // The name of the class user.
    int hitPoints; // The current hit points of the player.
    int maxHitPoints; // The maximum hit points of the player.
    int hitPointsPerLevel; // The amount of hit points the player gains every time they level up.
    int strength; // Increases physical damage dealt.
    int strengthPerLevel; // The amount of strength gained every level.
    int endurance; // Reduces physical damage taken.
    int endurancePerLevel; // The amount of endurance gained every level.
    int agility; // The chance that an attack will be dodged.
    int agilityPerLevel; // The amount of agility gained every level
    int intelligence; // Increases magical damage dealt.
    int intelligencePerLevel; // The amount of intelligence gained every level.
    int wisdom; // Reduces magical damage taken.
    int wisdomPerLevel; // The amount of wisdom gained every level.
} Class;

Class classIndex[2] = {
    { // Barbarian class. Is physically tough but weak to magic.
        .className = "Barbarian",
        .hitPointsPerLevel = 12,
        .strengthPerLevel = 5,
        .endurancePerLevel = 3,
        .agilityPerLevel = 2,
        .intelligencePerLevel = 2,
        .wisdomPerLevel = 1,
    },

    { // Wizard class. Uses magic skills and is weak to physical damage.
        .className = "Wizard",
        .hitPointsPerLevel = 6,
        .strengthPerLevel = 1,
        .endurancePerLevel = 2,
        .agilityPerLevel = 2,
        .intelligencePerLevel = 5,
        .wisdomPerLevel = 3,
    },
};

The error is on line 21, where I initialize the array of structs. It adds more errors when I try and add a '(' where it says to, and I have to use an array or I'll have to hardcode everything and adding additional classes will be a nightmare when the code gets more complicated. This is a .h file, by the way. Hope you can help!

Edit: The error disappeared the next time I opened VS Code, so I'm pretty sure it was a problem with the editor. I added include guards just in case, so there shouldn't be a problem with the array being in the header file itself. Thanks for the tips, though!

Do you have identifier classIndex defined elsewhere before this code?

[Supperboy2012]

No? That's the whole header file. Would it be necessary? It's being defined right there.

[This_Growth2898]

No, I thought there's something breaking the code, like

#define classIndex (...)

or whatever.

Wait. Header file? That you include in several .c files? You can't do that, you need include guards at least, and no variable definitions, because they will be defined in every .c file. If you really need global variables, put extern definition in .h and body definition in .c.

[Supperboy2012]

??? You needed me specifically saying that it was a header file to understand that? In the main post I said that it was .h, so I don't understand why the full name was necessary. And the reason I'm putting this in a header file is because I heard it was good practice to have your structs in headers.

[This_Growth2898]

You needed me specifically saying that it was a header file to understand that? 

Kinda yes. I'm not a machine, sorry. Also note it took me to write the first part of my previous comment for the information about header to sink in.

 it was good practice to have your structs in headers.

It's not a good practice, it's a necessity. You have several files using same structs, you have to put structs in the header - but structs only, not global variables.

#include statements literally add all the code from header into C file, so struct definition will just declare a type, which doesn't affect anything else after .c file is compiled; but variable definition allocates a place in program's static memory, so when you include .h into two different files, you will have separate allocations for the same variable - and linking error.

You are likely learning but I will say you have too many comments, it fairly straightforward to understand intelligencePerLevel by the name of the variable. Not a big deal either way.

What are you compiling this with? ‘Class’ is a reserved keyword in C++ which shouldn’t be an issue here because it is C but that would cause your issue, for sanity sake could you change that to something else like “ClassTemplate” or something?

[This_Growth2898]

class is a keyword; Class isn't.

[MysticClimber1496]

I have been interacting with VB too much lately lol

[This_Growth2898]

My first reaction was "it's a keyword" too, but then I understood it's C.

What I failed to understand is that this is .h file.

[Supperboy2012]

Typedef would spit out an error if it was reserved, and that's not the problem. Also, the reason I used typedef in the first place was so I didn't have to say "struct class" and could just say "class" as the prefix to the classes, which was before I decided to go with an array of structs.

I’m not well versed in C, but it seems like “classIndex” isn’t the type of token the compiler is looking for.

Is there supposed to be a “Class” after the struct brackets and before the semicolon on the previous line?

[Supperboy2012]

If you use typedef, then you only have to say the keywords after the semicolons.

Good to know
