I don't understand where I made a mistake

Question

I tried this code after documenting myself :

struct person
{
    int a;
    char s;
};
struct person test;
test.a = 12;

And Code::Blocks returns this following error :

error: 'test' does not name a type

Can someone explain this error to me? I found this sample code on the internet! I don't understand my mistake.

Thanks for reading, have a nice day.

To make your code work you need to put it in a function and there should be a main function too.

struct person
{
    int a;
    char s;
};

int main() // you need to have a main 
{
    // code needs to be in a function

    /*struct*/ person test; // struct is not needed 
    test.a = 12;

    return 0;
}
