Write a C# program to help balance your bank account (initialize the balance to 0 in Main()). The Main () method is to use a do-while loop to repeatedly prompt the user to enter a transaction (char) which could be 'w' or 'W' for withdrawal, ‘d' or 'D' for deposit, 'p' or 'P' for print, and 'q' or 'Q' for quit. Using a switch statement in the do-while loop, select the appropriate action and call the appropriate user-defined method. The Main () method should continue accepting transactions until the user enters a 'Q' or 'q'. If the user wishes to withdraw or deposit, Main () is to invoke a user- defined method to input a non-negative amount. The program is to have four user-defined methods: (i) A double method call GetAmount which takes no formal parameters but returns a non-negative value representing the amount of a deposit or withdrawal. This method is to be invoked by Main) when the user chooses to either withdraw or deposit to their account. The method is to prompt the user to enter an amount and then validate that it is non-negative. The method header should look like: public static double GetAmount () (ii) A void method called Withdrawal which accepts one call by value formal parameter of type double (the amount of the withdrawal) and one call by reference formal parameter of type double (the account balance). Withdrawal then deducts the amount of the from the balance. A $1.75 service charge is applied to each withdrawal. The withdrawal (and service charge) should not be applied if it would leave a negative balance and the customer should be warned (an error message should be printed). The method header should look like: public static void Withdrawal (double amount, ref double balance) (iii) A void function called Deposit which accepts one call by value formal parameter of type double (the amount of the deposit) and one call by reference formal parameter of type double (the account balance). Deposit then adds the amount of the deposit to the balance. If the amount of the deposit is greater than or equal to $2000, the customer receives a 2% bonus on the amount of the deposit (e.g., if $2000 is deposited, then add $2040 to the account). The method header should look like: public static void Deposit (double amount, ref double balance) (iv) A void function called Print which takes one call by value formal parameter of type double which contains the balance and then prints it out. The method header should look like: public static void Print (double balance)
