Concepts

1. How do you dynamically allocate and initialize a structure?

   "Student *s = (Student *) malloc(sizeof(Student) * 1); The multiplication by 1 in this example is not strictly necessary, but emphasizes the fact that we are allocating space for one structure and not

2. How do you access members of a statically declared structure?

   "Once we have a declared structure, we need to access its member variables and perhaps update them. If we have a statically declared structure, such as Student s; we can use the direct component selec

3. How do you access members through a pointer to a structure?

   "When we have a pointer to a structure, we cannot directly use the dot operator. Instead, we have to change the pointer into a “normal” structure by dereferencing it, then we can use the dot operator.
