1.How do you use a decomposition strategy to design a menu-driven calculator that supports four basic arithmetic operators - addition, subtraction, multiplication, and division? To design a menu-driven calculator using a decomposition strategy , you break the problem into smaller, manageable sub-tasks. Here's how to approach it step by step: 1. Problem Decomposition Break down the calculator into smaller components based on the tasks: Input Handling : Accept user input for numbers and operator selection. Operation Implementation : Define how each arithmetic operation (addition, subtraction, multiplication, and division) will be performed. Menu Management : Create a menu interface that allows users to select the desired operation. Output Handling : Display the result of the operation. Program Loop : Allow users to perform multiple operations by looping until they choose to exit. 2. Design Components The key components of the calculator can be: Input Functions : For accepting nu...

Learning Objective: Learn to write functions and recursive functions Functions and Recursive Functions 1.Write a function to check whether the given number is even or odd. ( return True or False) 2.Write a function to find the sum of numbers between a lower bound and an upper bound 3.A program that accepts the lengths of three sides of a triangle as inputs. The program should output whether or not the triangle is a right triangle (Recall from the Pythagorean Theorem that in a right triangle, the square of one side equals the sum of the squares of the other two sides). Implement using functions. 4. Write a function that returns True if a given number is prime and False otherwise.Use this function to print all prime numbers less than N. Read N. Use the same function to print n'th prime number. 5.Write a Python program to calculate the area of a circle, given the center and a point on the perimeter. Use a function to find the radius as the distance between two points . 6.Compute nCr...
