I have a struct :

struct ABC
{
   int size;
   int arr[15];
};

I know I cannot make ‘int size’ as ‘const int size’ so how can I keep the size member from being modified accidently/intentionally.Is there a way around in C?

Thanks.

    It can be const:

    struct ABC
{
   const int size;
   int arr[15];
};

int main() {
    struct ABC a = {3, {1,2,3} };   // ok
    a.size = 42;    // error
}
