Q$4(25$ pts$).$ Write acomplete $C++$ program that performs the following:

Your program should contain a find average function and a main function.

Assume that all stack behaviors are already present in a file called stack.h and hence you can #include "stack. h$".$ The function void findavg$($struct stack $*$s$1,$ struct stack $*$s$2)$ which takes two stacks as its arguments and pushes elements of stack s$1,$ which are smaller than the average of all elements, into stack s$2.$ Pay attention that the elements in stack s$1$ should be preserved.

In your main function:

Create two stacks s$1,s2$ with size $6.$

Fill the stack s$1$ by accepting user inputs.

Call your function findavg and fill s$2.$
