need help to make a calcuator in link list in C

a program that will act as asimple interactive calculator. Your calculator should include +, -, and *. Your calculator should also have “undo”and “redo”functionality. Implement the “undo”and “redo”functionality using two Stacks implemented with linked lists. Each node in both stackswill include an operator and integer [login to view URL] and pop operations should notbe duplicated for the two stacks Sample Output: C Calculator+----------------+ Enter starting value: 7 Enter next operation (u-Undo, r-Redo, q-Quit): + 13 Result= 20 Enter next operation (u-Undo, r-Redo, q-Quit): * 5 Result = 100 Enter next operation (u-Undo, r-Redo, q-Quit): u Result = 20 Enter next operation (u-Undo, r-Redo, q-Quit): r Result = 100 Enter next operation (u-Undo, r-Redo, q-Quit): / 20 ***Not a valid [login to view URL] next operation (u-Undo, r-Redo, q-Quit): y***Not a valid operation Enter next operation (u-Undo, r-Redo, q-Quit): r ***Not a valid operation Enter next operation (u-Undo, r-Redo, q-Quit): u Result = 20 Enter next operation (u-Undo, r-Redo, q-Quit): u Result = 7 Enter next operation (u-Undo, r-Redo, q-Quit): u ***Not a valid operation Enter next operation (u-Undo, r-Redo, q-Quit): r Result = 20 Enter next operation (u-Undo, r-Redo, q-Quit): q The main() function should be an outline of what the program does. All “details”of the tasks should be placed in functions. •first make a list of tasks the program will need to perform •decide which tasks to make into functions
