When should you use a union type component in a structured variable?
Eduardwww [97]

Answer:

The answers to 1st question and part 2A is given. However, the 2B is not given complete and thus cannot be answered.

Explanation:

UNION is a keyword used in C Language to have a commonly shared memory that can be used by multiple elements. It is a data-type that allows different data types to use the same shared memory location.

Importance: If you want to minimize the use of memory by sharing it between different datatype variables, then use UNION. For Ex. Let's suppose I want to use 2 variables a and b of type char and int respectively. Now, suppose int takes memory space of 2 bytes and char takes 1 byte then the total amount of memory needed = 2 + 1 = 3 Bytes. But, we want to first make use of a, and once done, we want to declare variable b. We can limit the memory use by declaring a memory space of 2 bytes (max of a and b). First, we can use this space to store the int variable and when done with it, we can use it to store the char variable.

PART 2A

typedef struct{

  int partNum;

  char partName[25];

} partin;

#define Partin partin

1. Write a program that grades arithmetic quizzes as follows: (4 points) a. Assume there are 23 questions in the quiz. b. Ask th
const2013 [10]

Answer:

import java.util.Scanner;

public class Grade

{

public static void main(String[] args) {

   

    final int LENGTH = 23;

    int keys[] = new int[LENGTH];

    int responses[] = new int[LENGTH];

    int i = 1, correctCount = 0;

   

    Scanner input = new Scanner(System.in);

    do {

       

        System.out.print("Enter the key for answer " + i + ": ");  

        int key = input.nextInt();    

        keys[i-1] = key;

       

        System.out.print("Enter your response to question " + i + ": ");  

        int response = input.nextInt();    

        responses[i-1] = response;

       

        if (keys[i-1] == responses[i-1]) {

            correctCount ++;  

        }

        i++;

    }

   

    while(i <= LENGTH);

   

    double percentage = (double)correctCount / LENGTH;

   

 System.out.println("Number of the correct answers: " + correctCount);

 System.out.println("Percentage of the correct answers: " + percentage);

}

}

Explanation:

- Initialize the variables

Inside the do-while loop :

- Ask for the answer key and put the values in keys array

- Ask for the responses and put the values in responses array

- If values at the same position in both arrays are equal, increase the correctCount, that means the response is correct

- Print the correcCount and percentage
