array type has incomplete element type struct

The error message "array type has incomplete element type struct" typically occurs when you declare an array of a struct type without providing the complete definition of the struct. To resolve this error, you need to ensure that the struct definition is complete before declaring an array of that struct type.

Here's an example to illustrate this:

struct Person {
    char name[50];
    int age;
};

int main() {
    struct Person people[5]; // This is a valid declaration because the struct definition is complete.
    // ...
    return 0;
}

In the example above, the struct definition for Person is complete before declaring an array of Person structs. This ensures that the compiler has all the necessary information to allocate memory for the array.

If you encounter the "array type has incomplete element type struct" error, you should check if the struct definition is complete and make any necessary adjustments to ensure that it is.
