Create an application that writes a series of random numbers to a file. Each random number should be in the range of 1 through 100. The application should let the user specify how many random numbers the file will hold and should use a SaveFileDialog control to let the user specify the file's name and address.

PrintWriter and Scanner - text file I/O DataInputStream and DataOutputStream - binary file I/O RandomAccessFile - binary file i/o where every record is the same number of bytes so that you can seek to a specific record ObjectInputStream and ObjectOutputStream - read and write objects.

You will create the following menu Menu Create text file Sum of Numbers Average of Numbers Exit Program Enter your choice: If a user enters a value other than 1 thru 4 make them renter a correct value Details about each menu option: Create Text File Ask the user to enter values and then write each value to a text file called numbers.txt. User is required to enter a minimum of 5 numbers. After entering 5 numbers, user should be given a choice to enter more. Numbers entered here will be used this in choices # 2 and 3 of this program. 2 Sum of Numbers Program should read content of the text file created in step 1. Display file content in a tabular format, example shown below. Notice that the very last line displayed contains the Sum of the numbers the file contains. Number------------ 12 3 10 2 22 ----------- Sum : 49 Design the code to handle exceptions. If file numbers.txt has not been created yet, display an appropriate message that notifies the user that file does not exit....

C++ Visual Studio 2019 Write a program that asks the user for the name of a file. The program should display the contents of the file on the screen. Each line of screen output should be preceded with a line number, followed by a colon. The line numbering should start at 1. Here is an example: George Rolland 127 Academy Street Brasstown, NC 28706 If the file's contents won't fit on a single screen, the program should display 24 lines of output at a time, and then pause. Each time the program pauses, it should wait for the user to strike a key before the next 24 lines are displayed. Note: Save text below as the file to use and name it forChap12.txt file for this assignment. The line numbers should NOT be reset for each screen.

The Pinewood Derby involves racing Derby cards down multiple lanes and calculating the average time to determine the winner. Create a program that prompts the user to enter in the number of racers that are competing. For each racer that is competing, the user should be specified to enter in four race times and the program should display the average of those times. That data should be then saved to a file. The program should drop the racers slowest time and calculate the average of the remaining times to determine a winner. Note: The most common error I see is that people drop the fastest race time, not the slowest. The program does not need to report who won; the program just needs to display the adjusted average for each racer.

C Sharp Random Number File writer and Reader Create an application that writes a series of random numbers to a file. Each random number should be in the range of 1 through 100. The application should let the user specify how many randome numbers the file will hold and should use a SaveFileDialog control to let the user specify the file's name and Location. Create another application that uses an OpenFileDialog control to let the user select the file that was created above. This application should read the numbers from the file, display the numbers in a ListBox control and display: the total of the numbers and the number of random numbers read from the file.
