What is the difference between structure and pointer?
A structure is a collection of primitives or other structures. A pointer is a memory address. Comparison of the two is like comparing bowling balls to cinder blocks. You can say that a structure defines the layout of the data, while a pointer points to data that is a particular structure.

What happens if we use an integer pointer as a member of structure instead of structure pointer?
By declaring an integer pointer you are declaring that any non-zero reference stored in the pointer is guaranteed to be an integer reference. In order to guarantee the reference is actually a structure, the pointer must be declared as such, because casting an integer to a structure can never be regarded as being type-safe.
When would you use a pointer and a reference variable?
pointer: to access data by address reference: there is no reference in C language
Time taken to insert an element after an element pointed by some pointer in data structure?
O(n)
What is heterogeneous linked list?
Heterogeneous Linked List is a linked list data-structure that contains or is capable of storing data for different datatypes.void pointer is basically used in these types of linked list as we are not sure of which type of data needs to be stored
What is the use of void pointer?
Void Pointer is a General purpose pointer ,that does not have any data type associated with it and can store address of any type of variable. Declaration: void * pointer_name;
