Problem Specification: (linked-list implementation required) a) Define an appropriate self-referential structure that contains at least 1 numeric, 1 character and 1 string data type. b) Manage the selected data using a stack. A data item should have a unique alpha-numeric identifier. c) The use of the atoi/atof ()or their reversal functions and gets () functions are strictly not allowed. d) Achieve appropriate error checking and robustness by avoiding the use of the scanf () function. Instead, use fgets (), getchar, and strto () functions e) Global variables are strictly not allowed f) Ensure to consider the user experience and use a looping technique and a case selection structure to control selection from the following menu: STACK OPERATIONS 1) Top of Stack 2) Bottom of Stack 3) Push 4) Pop 5) Print all the data items 6) Exit Stack Application
