c structure errors

[omighty]

im a student of c and cant get why this program keeps bringin me errors
thanks for the help

#include<stdio.h>
main()
{
    struct database[20];
    {
char namec[6];
int work_h;
    };
}

Where is the declaration for the struct database?

in the start of the structure
struct database

[r035198x]

in the start of the structure
struct database

Oh. Your code should look something like this

 
struct database
{
char namec[6];
int work_h;
};
 
 
main()
{
struct database[20];
}
 

You should read a structures tutorial.

i see thank you

[omighty]

but i want the structure to be inside the main

I don't think you can define a struct within main(), but if it is possible, I imagine it looks like:

int main() {
   struct database {
      // struct stuff here...
   };
   database db[20];
   // operations here...
}

}

thanks alot it works
now what does the db stands for?

[Ganon11]

That's just the name of the array variable. You can use whatever you want/need to name the array - I used db because db = DataBase.

yes but why do you need another variable isnt database enough
thats what i dont understant

Are you talking about where he says:
database db[20];
?

This initial code is fine without the first semicolon and correcting the definition of main.

#include<stdio.h>
main()  /* main should be declared int main(int argc, char **argv)
{
    struct database[20];  /* <-- semi-colon here is an error */
    {
        char namec[6];
        int work_h;
    };
}

int main() {
   struct database {
      // struct stuff here...
   };
   database db[20];
   // operations here...
}

This is fine in a C++ environment but the title states C and in C structure names are not automatically defined so this should be

int main() {
   struct database {
      // struct stuff here...
   };
 
   struct database db[20];
   // operations here...
}

However you can define the structure and declare the data in 1 statement with no problem as

int main() {
   struct database {
      // struct stuff here...
   } db[20];
   // operations here...
}

You have also missed out the int argc and char **argv required by the most common C stanadrd in use today (C89/C90) but I will let this pass as you probably had you C++ head on.

In Ganons example database is not a variable name, it is the name of a structure i.e. a type name.

Exactly. I'm not even sure I have a C head to wear...everything about C I know, I've learned from TSDN (and overlap with C++).
