2. Assume you are building a database for the school football team. People are constantly being enrolled and dropped out of the team. Your job is to keep track of the players. The players can be identified by their assigned 3-digit number (eg. 759, 412). Build a system using the most appropriate data structure following the sample output. Sample output: Inserted! Inserted! Inserted! Number of players: 3 No. : 596, 132, 328 Dropped! Number of players: 2 No. : 132, 328 3. Given a string of length n print the string in reverse using stack. For instance "LabTest" should be converted to "tseTbal". 4. Write a program that asks the user to enter 2 integers as inputs to be stored in the variables 'inta' and 'intb'. There are also two integer pointers named pointerA and pointerB. Assign the values of 'inta' and 'intb' to pointerA and pointerB respectively and display them. Your output should look like this: Value of pointer is x stored in address y
