Programming Assignment #1

Description

1. Write a program that converts the date, which is given in days, to “Year: <years>, Mount:

<mounts>, Day: <days>” format.

1. • 1 year has 365 days, 12 mounts

1. • 1 mount has 31 days

1. • Test your program to be sure it works on different values

Example Run 1

Example Run 2

Example Run 3

2. Write a program that will calculate the compound monthly interest. The program asks user to enter value of principle (p), annual interest rate (r) and time (t) and finally calculates the

compound interest by following formula.

= ∗(1+₁₂)

A: Final amount

16. Initial principle balance r: interest rate

t: number of time periods (in terms of months)

• Test your program to be sure it works on different values

• The annual interest rate is a number in percent format (9.45%)

• Print output values with up to 2 digits after the decimal point.

Example Run 1

Example Run 2

Example Run 3

Important Notes:

• The outputs of your programs must be the same as the examples above.

• Only parts selected from the selected questions will be graded. So if you send only one program, you might get a grade of 0 based on our evaluation.

• Please be sure that your programs should run properly on both your computer and a different computer.
