The format of each line of the file is the following: <last name> <hours worked> <hourly wage> Write a program that inputs a filename from the user and prints to the terminal a report of the wages paid to the employees for the given period. The report should be in tabular format with the appropriate header. Each line should contain: An employee’s name The hours worked The wages paid for that period. An example of the program input and output is shown below: Enter the file name: data.txt Name       Hours            Total Pay Lambert        34                  357.00 Osborne         22                137.50 Giacome tti      5                503.50

DCP 5101 PROGRAM DESIGN QUESTION 2 Write a complete C program that creates a new file called audio.txt for both writing and reading. The program prompts user to enter a series of inputs to calculate the audio size. User inputs and audio size are then written into file audio.txt. In main(): Open a new file called audio.txt for writing and reading. If the file can't be opened, display error message "File could not be opened. Program aborted." And quit the program. Using a do-while loop: o Prompt user to enter audio channel (either 1 for mono or 2 for stereo), sampling rate, time, and bit depth. o Calculate audio size. ● ● ● O O ==== From the beginning of file audio.txt, read and display all data from each audio record until the end of file. Close file audio.txt before program ends. SAMPLE OUTPUT 2 1 ■ Formula: audio channel x sampling rate x time x (bit depth / 8) Write audio channel, sampling rate, time, bit depth and audio size into file audio.txt.

Use C++ Write a program that prints a menu of choices: L -> Find the lowest value in a file H -> Find the highest value in a file A -> Find the average value in a file Q -> Quit Choose: The program does input validation and asks the user to reenter as long as the user’s choice does not correspond to an item on the menu. Invalid choice. Re-enter: If the user selects any valid choice other than Quit, the program prompts the user to enter the file name, Enter input file name: then reads the content of the file and prints the value requested (highest value, lowest value or average value). Highest value is 0 Lowest value is 0 Average value is 0 If the file cannot be opened or is empty, the program should display the message: File empty or could not open file Then the program displays the menu again. If the user selects Quit, the program prints “Exiting” and terminates. Additional requirements – Make sure you meet all the requirements You are not allowed to use arrays You are…

You have the following function. 1 def funct(a): file = open('file.txt') 3 while True: line = file.readline() if a in line: 4 print(line) file.close() 7 The contents of the file named file.txt is as follows: python python is great! python is the best python is amazing! What would the value of a be if the output is: python is great! python is amazing! Answer:

Program specifications:  Write a function called rCopy that copies the entire contents of one file to another, but copies them over in reverse order. This function should take the names of the input and output files as strings. If either file does not open for any reason, the function should output an error message stating the name of the file that didn’t open and then return the value false. Otherwise, if both files open correctly, the function should return true once the reverse copy has been completed. For example, if a file named in.dat contains the following: A c d 87arc 65879 9 then after the function call: rCopy("in.dat", "out.dat") the file out.dat should contain the following: 9 97856 cra78 d c A You must solve this recursively!! To implement this recursively you will need to write a helper function that passes in an input and an output file stream. This helper function will be the recursive function. Recall that the expression cin.get(ch) will read in a single character from…

Programming Exercises As mentioned before, you will be answering all the following questions in one single python file and the person running your file will be prompted to choose which one of these programming exercises they wish to run. A good approach to design this file is to have a main function for each of the questions (main1, main2, etc.). These functions will be called when the user chooses each of the questions (if the user chooses 1, mainl will be executed and so on). You can call different functions in each of your mains if you wish. Below are the programming exercises. The questions are in all levels, some of them are very easy, and some are more challenging. Start with the questions that are easier for you and then try to answer as many questions as possible. For grading, we will be looking at the codes, so even if you have not completely answered a question, make sure you still include your code in the submitted file as you may receive a partial grade for it. Note: all…

In C Language

Language: Python 1. The sample input will have to be in Text File (.TXT) 2. By using the first function, this program reads score and name values from a file. The program then determines the grade for each students by using the second function. Finally, the program displays the name, score, and grade information on the console. The two functions are shown in the images attached below:

Q2: Write a complete C++ program that reads the contents of the text file "mydata.txt", character by character. And appends them to the end of text file "myoutput.txt" . The main function calculates and prints the number of characters read and copied between the files.

Directions: Typing make at the command line should create executable named bitflip. Only bitflip.c and Makefile are included in the input unless permission is given for any other files.  Program should have consistent indentation. Code should be readable with good variable and function names. No use of "break or continue statements" except in a switch. Program must exit with a return code of 0 on success and an error code in other cases. The program used getopt to parse the command line. Whenever an error occurs on the command line the user is given the usage statement and an appropriate error message if needed. If the -­o option is used the output will go to a file named as specified without changing the filename at all otherwise it will go to stdout. -e option works as specified using bitwise operations. -f option works as specified using bitwise operations. -a option works as specified using bitwise operations. -s option works as specified using bitwise operations. Program outputs…

1 Write a program that writes a series of random numbers to a file. Each random number should be in the range 1 through 500. The application should let the user user specify how many ran- dom numbers the file will hold. Use an excep- tion to make sure that an integer was typed in by the user for the #to generate. If not re ask the user for input in the except clause until they input the correct number. You should do this in one function named main
