- 1. Write a C++ program that takes two binary numbers of 8 bits eachrepresented with the letters Z and O (for zero or one) and displays thesum in binary with Zs and Os. Do this by converting the numbers to ints,adding the its using +, displaying the 3 ints, then converting the sum toZ and Os and displaying the result. 1 a.) Redo number 1, by doing a bit-by-bit addition, not forgetting the carry. 1b.) Write a program to take two numbers represented with romannumerals and display the sum. Assume the sum will be less than 20.Hints: Ask the user to terminate each number with a semicolon and usechars to hold the roman ‘digits’.The numbers are I, II, III IV, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV…isfive, Change the program to allow the sum to go up to 49 See how large a number you can handle. L is 50, C is 100, M is 1000. Using basic C++ int, char, if- else statements, and switch statements, please! no functions, or strings, or Cmath etc.(a) Suppose we agree to represent integers using 8-bit signed integers (also known as the two’scomplement method).(i) Use set-roster notation and decimal notation to describe the set of integers that may be representedusing 8-bit signed integers.Suppose we number the bytes in a w-bit word from 0 (least significant) to w/8 – 1 (most significant). Write code for the following C function, which will return an unsigned value in which byte i of argument x has been replaced by byte b: unsigned replace_byte (unsigned x, int i, unsigned char b); Here are some examples showing how the function should work: replace_byte(0x12345678, 2, 0xAB) --> 0x12AB5678 replace_byte(0x12345678, 0, 0xAB) --> 0x123456AB Bit-Level Integer Coding Rules In several of the following problems, we will artificially restrict what programming constructs you can use to help you gain a better understanding of the bit-level, logic, and arithmetic operations of C. In answering these problems, your code must follow these rules: Allowed operations All bit-level and logic operations. Left and right shifts, but only with shift amounts between 0 and w – 1. Addition and subtraction. Equality (==) and inequality (!=) tests. (Some of the problems do not allow…
