Allocation of memory for char array

Question

Let\'s say you have-

struct Person {
    char *name;
    int age;
    int height;
    int weight; 
 };

If you do-

struct Pe         


        

Answer 1

You have a pointer to a name character array in your struct, ie. it will consume that much bytes that are needed to represent a memory address.

If you want to actually use the field, you must allocate additional memory for it.
