Question

Suppose you have a certain amount of money in a savings account that earns compound monthly interest, and you want to calculate the amount that you will have after a specific number of months. The formula, which is known as the future value formula, is:

F = P X (1 + i) t

The terms in the formula are as follows:
- F is the future value of the account after the specified time period.
- P is the present value of the account.
- i is the monthly interest rate.
- t is the number of months.

Write a program that prompts the user to enter the accountâ€™s present value, monthly interest rate, and the number of months that the money will be left in the account. The program should pass these values to a function named futu.

double futureValue(double present_value, double monthly_interest_rate, int months_left){
double F ;
F = present_value * (1 + monthly_interest_rate) * (double)months_left;
return F;
}

int main(int argc, char** argv) {
// variable declaration
double present_value;
double monthly_interest_rate;
int months_left;

// get user input
cout<<"Enter the account's present value : ";
