Here, we calculate the theoretical price of a Consol bond.
Let r1 be the interest rate for the first n years, including the current period,
and let r2 be the interest rate starting from year n+1.
The program outputs the market price of the Consol bond in this case.
Enter the interest payment amount c for each period.
Set the interest payment date for the current period to one year from now, and enter n for n years.
Enter the interest rate for n years.
(Enter 0.15 for 15 percent, or 0.08 for 8 percent.)
Enter the interest rate for n+1 years and beyond.
Enter non-negative values for c, r1, and r2.
Enter a non-negative integer for n.
Input that exceeds the limits may not be processed, depending on the validation.

The r1 and r2 checkmarks in the output field display a “1” to alert you when the entered values for r1 or r2 are 1 or greater.
If there are no issues, a “0” is displayed.
