Question: Modify the stack example so that it stores characters instead of integers.
Next, add a main function that asks the user to enter a series of parentheses and/or braces, then specify whether or not they are properly nested:
Enter parentheses and/or braces: ((){}{()})
Parentheses/braces are nested properly.
Can you modify the stack so it stores characters instead of integers?
Please show all your work and give an explanation of steps
