Using the switch statement, write a menu driven program to calculate the maturity amount of a Bank Deposit.
The user is given the following options :
(i) Term Deposit
(ii) Recurring Deposit

For option (i) accept principal (P), rate of interest(r) and time period m years(n). Calculate and output the maturity amount (A) receivable using the formula

`"A" = "P"[1+"r"/100]^"n"`

For option (ii) accept Monthly Installment (P), rate of interest (r) and time period in months (n). Calculate and output the maturity amount (A) receivable using the formula

`"A" = "P" xx "n" + "P" xx ("n"("n" + 1))/2 xx "r"/100 xx 1/12`

For an incorrect option, an appropriate error message should be displayed.
