Question : note : read the instructions carefully In this Question, you are required To understand and analyze carefully the problem in hand Convert given C language code in C++ by defining your own set of classes. From problem understanding perspective write a short analysis in adopting object oriented approach over structured approach for the given case study. C Program to Display the ATM Transaction This C Program performs ATM transaction. The types of ATM transaction are 1) Balance/Amount checking 2) Cash withdrawal 3) Cash deposition   Problem Solution Firstly initialize the ATM pin and amount with some random number. Take the ATM pin as input. If the input pin is equal to the initialized pin, then do the further operations. Use switch statement to do the operations like Balance checking, Cash withdrawal, Cash deposition etc. Use while loop to terminate or restart the process. /*  * C Program to Display the ATM Transaction  */ CODE SKELETON IN STRUCTURAL APPROACH #include unsigned long amount=1000, deposit, withdraw; int choice, pin, k; char transaction ='y'; void main() {                 while (pin != 1520)                 {                                 printf("ENTER YOUR SECRET PIN NUMBER:");                                 scanf("%d", &pin);                                 if (pin != 1520)                                 printf("PLEASE ENTER VALID PASSWORD\n");                 }                 do                 {                                 printf("********Welcome to ATM Service**************\n");                                 printf("1.
