# Lesson 2.Integer and float numbers

## Problem «Last digit of integer»

#### Statement

Given an integer number, print its last digit.

## Problem «Tens digit»

#### Statement

Given an integer. Print its tens digit.

## Problem «Sum of digits»

#### Statement

Given a three-digit number. Find the sum of its digits.

## Problem «Fractional part»

#### Statement

Given a positive real number, print its fractional part.

## Problem «First digit after decimal point»

#### Statement

Given a positive real number, print its first digit to the right of the decimal point.

## Problem «Car route»

#### Statement

A car can cover distance of N kilometers per day. How many days will it take to cover a route of length M kilometers? The program gets two numbers: N and M.

## Problem «Digital clock»

#### Statement

Given the integer N - the number of minutes that is passed since midnight - how many hours and minutes are displayed on the 24h digital clock?

The program should print two numbers: the number of hours (between 0 and 23) and the number of minutes (between 0 and 59).

For example, if N = 150, then 150 minutes have passed since midnight - i.e. now is 2:30 am. So the program should print 2 30.

## Problem «Total cost»

#### Statement

A cupcake costs A dollars and B cents. Determine, how many dollars and cents should one pay for N cupcakes. A program gets three numbers: A, B, N. It should print two numbers: total cost in dollars and cents.

## Problem «Clock face - 1»

#### Statement

H hours, M minutes and S seconds are passed since the midnight (0 ≤ H < 12, 0 ≤ M < 60, 0 ≤ S < 60). Determine the angle (in degrees) of the hour hand on the clock face right now.

## Problem «Clock face - 2»

#### Statement

Hour hand turned by α degrees since the midnight. Determine the angle by which minute hand turned since the start of the current hour. Input and output in this problems are floating-point numbers.
