- Write a python code that reads a file (contents of the file pasted below) and shows the average of all values shown in the last column. File Name: data.txt File Contents (of data.txt): Admin 100 300 tmp 20 Admin 100 300 tmp 30 Admin 100 300 tmp 20 Admin 100 300 tmp 10 Admin 100 300 tmp 60 Admin 100 300 tmp 95 Admin 100 300 tmp 100 Admin 100 300 tmp 24 Admin 100 300 tmp 99 Admin 100 300 tmp 50Directions: 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…4) Write a bash script to demonstrate until loop which displays "While Loop Demo" and exits when key q is typed.

If the file has less than 10 lines, the entire file is displayed, with a message that the entire file has been displayed. The program should do this by seeking to the end of the file and then backing up to the tenth line from the end.Consider the following code segment: done = False while not done : try : filename = input("Enter the file name: ") inFile = open (filename, "r") except IOError : print ("Error: File not found.") It is supposed to keep on prompting the user for file names until the user provides the name of a file that can be opened successfully. What line of code should be placed in the blank to achieve this goal? Select one: done = inFile done = True done = not inFile done = False
- Use Scanner and File to read input from a file. Use PrintStream and File to write output to a file. Write and call methods that accept parameters and return values to manage information flow and add structure to programs. Follow prescribed conventions for spacing, indentation, naming, and comments. Notice that if an input file is not found, either for creating a mad-lib or viewing an existing one, the user is re-prompted. No re-prompting occurs for the output file. If the output file does not already exist, it is created. If it does already exist, its contents are overwritten. (These are the default behaviors in Java.) You may assume that the output file is not the same file as the input file. When you are viewing an existing mad lib story, you are simply reading and echoing its contents to the console. You do not need to do any kind of testing to make sure that the story came from a mad lib input file; just output the file's contents. Menu options can be chosen in any order and are…Write a CPP program to do the following: Read the attached text file "DISTRICT-COSC-1437.txt". Uppercase each line and write the uppercase results to a file named "UpperCased1437.txt". This is the target file. If the target file exists when the program starts, prompt to overwrite the file. If declined, then do not process. Deliverable is a working CPP program.

If the given strings are the same length, write the first string given to the file. If the user does not provide the correct number of command line arguments, print an error message and exit the program with a non-zero exit code.

Each line should be read one at a time. For each word on a line, the user should be asked to specify how many syllables are in that word. The program should then inform the user if the file contains a valid Hiku using the function below: def isHiku (firstLine, secondLine, thirdLine):if (firstLine == 5 and secondLine == 7 and thirdLine == 5): return True return False print("The file contains a Hiku:", isHiku(5,7,5))Note: You must replace the values in the function with the numbers counted by your program.a. What happens if you try to move the file marker past the end of a file? b. What is returned if subsequent calls are made to read the file?
