First check the file stackType. h $($attached to this assignment$),$ which contains both the declarations and

definitions of the member functions for the Stack class. Write the functions to do the following:

Write a non$-$member function, named multiplyStackItemsBy$2,$ that multiplies every

element in an integer stack by $2.$ Do not use recursion. The function has the prototype of

void multiplyStackItemsBy$2($stackType$S2,-1,3,4,5,3,04,-2,6,8,10,6,0S2,-1,3,4,5,3,0S$ All your coding $($functions you write$)$ should be performed inside a file named hw$3.$cpp$.$ Just include

stackType.h within hw$3.$cpp$.$ Do not do any modification to stackType.h$.$ You are free to add a

main function in hw$3.$cpp to test drive your functions.

Submit only the file hw$3.$cpp$.$

Hint: Pattern for implementing the recursive functions:

Please consider the following code that represent a recursive function that will print the element

of the stack starting from the top element. Note that you are popping elements from the stack

while going down in the recursive calls and you re$-$push them while returning. You should follow

the same approach in implementing the needed recursive functions in the assignment.void printStackRec$($stackType
