Program Plan Intro

Operator “in”:

  • • The easiest way to search an item in a list is by means of “in” operator.
  • • The “in” operator in Python determines whether the searching item is present in a list.
  • • If the searching item is present in the list, then this operator returns a “True” value.
  • • If the searching item is not present in the list, then this operator returns a “False” value.

Algorithm:

Algorithm to find whether the name “Ruby” is present in the “names” list is as follows:

  • • Create a list of strings that stores names and assigns it to “names”.
  • • Then, use the “in” operator along with “if” statement to check whether the name “Ruby” is present in the list “names”.
  • • If the name “Ruby” is present in the “names” list, then print the message “Hello Ruby”.
  • • If the name “Ruby” is not present in the “names” list, then print the message “No Ruby”.

C++ Language
Program Name: <LastNameFirstInit>_PetShelter You work at a Pet Shelter that take in homeless pets. You have been tasked with creating a report that shows a list of all the dog breeds currently staying at the shelter. This list should include the breed name along with the count for each breedcurrently being housed at the shelter. In addition, at the end, the report should display the name of breed that we have the most (max) of currently at the shelter. In addition, your program should utilize methods for building the report and searching for the max breed count. Two parallel arrays have been provided. You can use the following code to get you started. //START CUTTING CODE HERE public class MichakR_PetShelter { public static void main(String[] args) { String[] breedNames = {"Bulldog", "German Shepherd", "Golden Retriever", "Beagle", "Poodle", "Boxer", "Mixed Dog", "Husky"}; int[] breedCounts = {2,5,3,1,8,1,11, 3};   //generate report   //get Max Breed   //print report   }   public…
Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
