Overview This program will welcome a user to the trivia builder 3000, then prompt the user to add questions to the trivia bank. After the user indicates they are done it will print out the contents of the trivia bank. Expected Output Example 1 Welcome to the trivia builder 3000 Enter the next question: Who was the fifth Beatle? Enter the correct answer for that question: Pete Best Enter the next question: You did not enter a question, let's try again. Enter the next question: How many dimples does a golf ball have Enter the correct answer for that question: 336 Enter the next question: Done We will stop entering questions now Here is the final trivia dictionary: The question is: Who was the fifth Beatle? And the answer is: Pete Best The question is: How many dimples does a golf ball have? And the answer is: 336 Example 2 Welcome to the trivia builder 3000 Enter the next question: What was the first name for the Beatles? Enter the correct answer for that question: The Quarymen Enter the...

C++arrays, c-strings, functions with arrays as parameters 1. Create a file that contains 20 integers or download the attached file twenty_integers.txt Create a program that: 2. Declares a c-style string array that will store a filename. 3. Prompts the user to enter a filename. Store the file name declared in the c-string. 4. Opens the file. Write code to check the file state. If the file fails to open, display a message and exit the program. 5. Declare an array that holds 20 integers. Read the 20 integers from the fileinto the array.6. Write a function that accepts the filled array as a parameter and determines the MAXIMUM value in the array.Return the maximum value from the function (the function will be of type int).7. Print ALL the array values AND print the maximum value in the array using a range-based for loop. Use informational messages.Ensure the output is readable.

Using the MATLAB editor, create a script m-file which includes a header block and comments: Create a matrix which holds values of: y=a^x where a is a column array A have values in the range 1-5 with 0.5 increments x is a row array X having integer values 1-5 Display the matrix results Save the script and publish function to create a pdf file from the script in a file named "ECE105_Wk2_L1_Prep_2"

Computer Science Please use go language programma to write this code. Write a program that creates a CSV file to store and retrieve data such as name, age, and salary. You should be able to read the data out of the file and display the data sorted by name. Hint: Make use of the Sort package to sort the data. Make sure you check the existence of the file, closing the file when there is an error Use defer, panic, and recover as needed.

Using the data file below design a hierarchical struct to organize the data. Then declare an array of structs for the reservations. The data file contains ten reservations. There are 8 columns of data: party name, size, date and time for the reservation, phone number, email address, credit card number and expiration date for the credit card. The data can be read from the file below so you will not need to type it in repeatedly. Once you have populated the array with data perform the following tasks: Write a function that will print out to the screen the information for one reservation.In the main program write code that prompts the user to enter a date in the form MM DD YYYYCall the function to print out all reservations on that date. You can make a loop that calls the print function repeatedly or you can put that code inside the print function.TEST CASES: April 30, 2023 and May 12, 2023. In this example you need to carefully consider what data types to use. For example, the credit...

C programming language Criteria graded: Declare file pointers Open file Read from file Write to file Close file Instructions: Write a segment of code that opens a file called "numbers.txt" for reading. This file is known to have 10 numbers in it. Read in each number and print a ‘*’ to the screen if the number is even. If the number is odd, do nothing. Conclude by closing this file.

Data: 45,30,50,25,60,55,75,70 From the data, do the sorting using 1. Selection sort method 2. Insertion sort method

Data File: Example #1AAAAABBBBBCCCCCDDDDDAAEBCBAFBBCDCECDADDEFEEFFFExample #2AAATAABTBBBBCCCCTCDDTDDDAASAABBSBBCCSCCDSDDDEEEAEEFBFFFDDF Write a program that will give the user a brief introduction, then allow the user to type in the name of the file to be analyzed, the name of the data file to generate, and then process the data to match the output that is shown below. This DNA test measures the various parts of the sequence and assigns them a letter. While the letters could be anything from A to Z, the only letters that matter for this test are the letters {A,B,C,D} all other letters can be ignored completely. A sample will be tested, given a length of time and then tested again. Each time the scientist will generate a line of data. Here is one Example: Example #1 AAAAABBBBBCCCCCDDDDD AAEBCBAFBBCDCECDADDEFEEFFF At first glance the sample looks significantly different after the second test. But if you look at the data, you will note that since we only care about A,B,C,D’s that the...
