Using C++ take this program and modify it to handle data input for the principal, annual interest rate, and number of months from the keyboard.
Using C++ take this program and modify it to handle data input for the principal, annual interest rate, and number of months from the keyboard. Use appropriate prompting messages, such as: "Enter the annual interest rate: Write a program that calculates earned simple interest given the principal (P), annual interest rate, and time (T) in months. The formula is I = P * R * T You must assign values to the variables in the program (no keyboard input during program run time). Example: float prin = 1200.0; R (rate) needs to be in decimal form. This means a 10% annual interest rate is represented as 0.1, 5% would be 0.05, etc. For the formula to work, the annual interest rate needs to be divided by 12 to get the monthly interest rate. (I = P * R/10/12 * T) Money, interest rate, and interest are real numbers, so use type float for them. To summarize, if the annual interest rate (AIR) is 8%, then R is AIR divided by 100 (convert to decimal form), and then divided by 12 (convert to monthly rate). There in no compounding (if you don't know what this means, don't worry about it). The result should be output to the screen in the following manner: Principal: $pppp.pp Annual Interest Rate: rr.r% Number of Months: mm Interest Earned: $iiii.ii Use the following test data in your program: principal: $1200.00 annual interest rate: 8.5% (.085) number of months: 12
