Kilobytes in Bytes One Kilobyte is 1024 bytes. Write a program that prompts the user to enter the number of bytes, then calculates and prints the number of equivalent kilobytes and the number of bytes. For example, if the number of bytes is 7835 then there are 7835 / 1024 = 7 kilobytes and 7835 % 1024 = 667 bytes. See sample input/output below: Sample input/output: Enter the number of bytes: 7835 There are 7 kilobytes and 667 bytes in 7835 bytes PIN Number Write a program that reads a three digit-integer and adds to it a fourth digit in the ten position to produce a valid bank PIN number. A valid bank PIN number is a four digit-integer has the property that the sum of its four digits is a multiple of 10. For example, if the number read is 725 then if we add to it in the ten position the digit 6 then we will have the new number 7265 with the property that 7+2+6+5 = 20 which is a multiple of 10. Sample inputs / outputs: Enter a 3-digit integer: 725 Enter a 3-digit integer: 721 The PIN number is 7265 The PIN number is 7201 Round a Decimal Number Write a program that prompts the user to enter a decimal number, rounds the number to two decimal digits, and prints the rounded number. Sample inputs / outputs: Enter a decimal number: 34.78306 Enter a decimal number: 572.83614 The new number is 34.78 The new number is 572.84
