Declaring and Using a Struct. To allocate memory for a struct we declare a variable using our new data type. struct flightType plane;. Memory is allocated
Dynamically allocated heap memory must be manually deallocated in C. ? Use malloc() and free() to allocate and deallocate memory from heap.
In static memory allocation variables are allocated on the stack and they go away when the function returns. When we allocate memory dynamically
