Write a program with two functions presentValue (), difference() beside main(). presentValue() function should accept the future value, annual interest rate, and number of years as arguments. It should calculate and return the present value, which is the amount that you need to deposit today. difference() calculates the difference from future value to present value. It should accept the future value to present value as arguments. presentValue () is then called from main() and if the future amount is greater than the present amount called the difference() function. And within it also check if present amount is greater than 0.5 and accordingly display the values of present amount, future amount, and number of years. Otherwise, display the message “The deposit value is less than or equal to $ 0.5".

Expert Solution
Step 1

Declare all the variables in the formula.

double p, f, r, t;

Declare the variable to hold the minimum deposit amount.

double amt=0.5;

 

All the variables are declared before main() method.

 

 

Step 2

Declare the methods as mentioned.

double presentValue(double, double, double);
void difference(double, double);

 

Both the methods are declared before main() method.

Step 3

Define both the methods as per the requirements.

 

Inside main(), take user input for the variables included in the formula.

Call both the presentValue() method.

 

If the value to be deposited is less than the future value, message is displayed to the user accordingly.

If the deposit value is less than or greater than 0.5, display the message to the user accordingly.
