Create union integer with members char c, short s, int i and long b. Write a program that inputs the values of type char, short, int, and long and stores the values in union variables of type union integer. Each union variable should be printed as a char, a short, an int and a long. D the values always print correctly? Also create pseodocode or flowchart.
Here is the feedback that I received when I originally turned this in:
I have the following concerns: You need to save your program file with a .c extension. You should declare your union above the main module and then utilize it from within this portion. You have declared the union and then created a function definition prior to entering the main() function.
Here is the original code provided by homework help: Thanks in advance
#include
union myUnion {
char c;
short s;
int i;
long l;
};
void print(myUnion u) {
printf("As a character: %c\n", u.c);
printf("As a short: %hd\n", u.s);
printf("As an int: %d\n", u.i);
printf("As a long: %ld\n\n", u.i);
}
int main() {
myUnion u;
printf("Please enter a character: ");
scanf("%c", &(u.c));
print(u);
printf("Please enter a short: ");
scanf("%hd", &(u.s));
print(u);
printf("Please enter an int: ");
scanf("%d", &(u.i));
print(u);
printf("Please enter a long: ");
scanf("%ld", &(u.l));
print(u);
return 0;

Answers

Answer:

The updated program in C is as follows:

#include <stdio.h>

union myUnion{ char c; short s; int i; long l; };

int main(){

   union myUnion inputs;

   printf("Character: ");    scanf("%c", &inputs.c);

   printf("Output: %c", inputs.c);

   printf("\nShort: ");    scanf("%hd", &inputs.s);

   printf("Short: %hd", inputs.s);

   printf("\nInteger: ");    scanf("%d", &inputs.i);

   printf("Output: %d", inputs.i);

   printf("\nLong: ");    scanf("%ld", &inputs.l);

   printf("Long: %ld", inputs.l);

   return 0;

   }

The pseudocode is as follows:

Function union myUnion {

character; short; int; long

}

main() {

myUnion inputs;

Input inputs.c;  Print inputs.c

Input inputs.s; Print inputs.s

Input inputs.i; Print inputs.i;

Input inputs.l; Print inputs.l

}

Explanation:

This defines the union function

union myUnion{ char c; short s; int i; long l; };

The main begins here

int main(){

This calls the union function to main

   union myUnion inputs;

This prompts and gets input for character variable

   printf("Character: ");    scanf("%c", &inputs.c);

This prints the character input

   printf("Output: %c", inputs.c);

This prompts and gets input for short variable

   printf("\nShort: ");    scanf("%hd", &inputs.s);

This prints the short input

   printf("Short: %hd", inputs.s);

This prompts and gets input for integer variable

   printf("\nInteger: ");    scanf("%d", &inputs.i);

This prints the integer input

   printf("Output: %d", inputs.i);

This prompts and gets input for long variable

   printf("\nLong: ");    scanf("%ld", &inputs.l);

This prints the long input

   printf("Long: %ld", inputs.l);

   return 0;

You have two microservices that need to communicate with each other without holding up a thread on either end. One service will receive an ID and return a message once the job is complete.
Which communication framework should be used?
A.) Have a shared database that allows both
applications to read and write to the tables to share the data instead of having to communicate
B.) Use asynchronous messaging to send and receive messages between each microservice
C.) Abandon the microservice architecture so no interaction is needed
D.) Create a third service to handle the interaction between the services
E.) Use a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available

Answers

Answer: E. Use a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available.

Explanation:

Since there are two microservices that need to communicate with each other without holding up a thread on either end, the communication framework should be used is a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available.

REST is a software architectural style which is used in defining the set of rules that be used for the creation of web services. The REST architecture allows requesting systems to be able to access and manipulate web resources.

If every company is now a technology company, then what does this mean for every student attending a business college

Answer:

Explanation:

There are all sorts of possibilities for, say, inserting new technologies into existing processes. But most of these improvements are incremental. They are worth doing; in fact, they may be necessary for survival. No self-respecting airline, for instance, could do without an application that lets you download your boarding pass to your mobile telephone. It saves paper, can't get lost and customers want it.

But while it's essential to offer applications like the electronic boarding pass, those will not distinguish a company. Electronic boarding passes have already been replicated by nearly every airline. In fact, we've already forgotten who was first.

In the right situations, the use of multi-threads can allow for application speedup. Provide a small code example that illustrates how threads can be used to arrive at an appropriate result. Identify if there is a point where too many threads might impact performance of the application. g

Answers

Answer:

Explanation:

Threads allow an applications to run faster because they allow various tasks to run at the same time instead of doing one at a time and having to wait for one to finish before starting the next task. However, if too many threads are running at the same time, or a thread has a very large task or requires another task to finish before finishing its own then this can drastically impact performance. Mainly because too many resources are being used at a single moment. The following code is a small example of how threads work in Python.

import threading

import time

def thread_function(name):

   print("Thread {name}: starting")

   time.sleep(2)

   print("Thread {name}: finishing")

thread1 = threading.Thread(target=thread_function, args=(1,))

thread1.start()

time.sleep(1)

thread2 = threading.Thread(target=thread_function, args=(2,))

thread2.start()

thread2.join()

Park Hyatt Philadelphia at the Bellevue, located at Walnut and Broad in downtown Philadelphia has a capacity of 240 king rooms. Customers of Hyatt are typically either leisure travelers or business customers. Hyatt charges a discount fare of $125 for a midweek stay (but requires booking a week in advance) which contrast the regular fare of $275. Typically, business customers book in the last minute, and are willing to pay the regular fare, if they can be guaranteed accommodation. Suppose we are interested in the bookings in Park Hyatt on August 6th (the day of our final exam). Hyatt knows that there are plenty of leisure travelers, willing to pay the low fares. However, all else being equal, Hyatt would like to fill those rooms with the high-fare travelers. The objective of Hyatt is to maximize the sum of revenue from both sections of the travelers. If Hyatt followed the booking limit policy, by reserving some rooms for last-minute business customers, how many rooms should it reserve? Assume that there is ample demand of leisure customers willing to pay the discount fare, and the number of business customers is normally distributed, with mean 50 and standard deviation 26.
