Problem
1. Assemble the appropriate declarations from the text into the files stack.h and stack.c and verify that stack.c compiles correctly, so that the class Stack can be used by future client programs.
2. Write a program that uses a Stack to read an integer and print all its prime divisors in descending order. For example, with the integer 2100 the output should be 7 5 5 3 2 2.
