Eduardwww [97]3 years ago

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

Write a program that allows a user to choose to roll between 1 and 100 dice between 1 and 1000 times
s344n2d4d5 [400]

Answer:

Here is a Python program that allows a user to choose to roll between 1 and 100 dice between 1 and 1000 times. The program uses a while loop to continuously prompt the user for input until they enter a valid number of dice and rolls. It also uses a for loop to simulate the dice rolls and a random module to generate random numbers for the dice rolls.

import random

while True:

   # Prompt the user for the number of dice to roll

   num_dice = int(input("Enter the number of dice to roll (1-100): "))

   if num_dice < 1 or num_dice > 100:

       continue

   # Prompt the user for the number of rolls to perform

   num_rolls = int(input("Enter the number of rolls to perform (1-1000): "))

   if num_rolls < 1 or num_rolls > 1000:

       continue

   # Simulate the dice rolls and print the results

   for i in range(num_rolls):

       roll = 0

       for j in range(num_dice):

           roll += random.randint(1, 6)

       print(f"Roll {i+1}: {roll}")

   # Ask the user if they want to roll again

   again = input("Roll again? (Y/N): ").upper()

   if again != "Y":

       break

Explanation:

In this program, we first import the random module to use its randint function to generate random numbers for the dice rolls. We then enter a while loop that will continuously prompt the user for input until they enter a valid number of dice and rolls. Within the while loop, we prompt the user for the number of dice to roll and the number of rolls to perform. If the user enters an invalid number of dice or rolls, we continue back to the beginning of the loop and prompt the user again.

Once the user has entered a valid number of dice and rolls, we use a for loop to simulate the dice rolls. For each roll, we use another for loop to roll the specified number of dice and add up the results. We then print the total for each roll. After all of the rolls have been performed, we ask the user if they want to roll again. If they enter "Y", we continue back to the beginning of the while loop to prompt them for new input. If they enter anything else, we break out of the while loop and end the program.

Overall, this program allows a user to choose to roll between 1 and 100 dice between 1 and 1000 times, and simulates the dice rolls using random numbers and loops.

Sound can be converted from the electrical energy inside a computer into the mechanical energy of soundwaves in air by using
kogti [31]

Answer:

a transducer

Explanation:

A transducer happens to be a device that is being used for converting one form of energy into another generally when converting the input energy to the output energy. And for the transduction to take place, the change of one form of energy also occurs, like the conversion of mechanical energy to the electrical energy and also from electrical energy to mechanical energy, and which is what is required here. Hence, the correct option here is the transducer.
