PYTHON without def function Problem Statement Assume an input file (called "numbers.txt") contains a number on each non-blank line of the file. Read in the file and then print out the sum of all the numbers read. The sum should be rounded up to 1 decimal.   Sample Input (File numbers.txt) 1.0 2.0 3.25 4.0 Sample Output 10.3

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.

What does the following python code do? f = open("sample.txt", "a") Choose all that apply.    Select 3 correct answer(s) Question 15 options:   opens a file called sample.txt for reading   reads the file called sample.txt starting from the top   writes "a" to the file called sample.txt    opens a file called sample.txt for appending   If the file called sample.txt exists, it writes at the bottom of the file   closes a file called sample.txt   if the file sample.txt exists, deletes everything in it   if the file sample.txt does not exist, it creates the file and opens it for writing

C program

1. string   color  =  "Yellow";      //What does this code do?   a. declares a structure   b. calls a function   c. creates a character array   d. creates an object   2. The strcmp function returns ____________________.   a. 0 if the two strings are equal   b. a negative value if the first argument is alphabetically less than the second   c. a positive value if the first argument is alphabetically greater than the second   d. all of a through c are true

Files Class Activity Write a program to write your first name (hard coded) to the screen and possibly to a file whose name is passed into the program from the command line. It can be written in upper or lower case or mixed case as the default. Usage: writer [-f filename] If the -f option is included with a filename, then create a file with that name or overwrite a previously existing file and write your name in on the first line. If the -f option is not included, then only write your name to the screen followed by a newline. Use a copy of the original getopt to parse the command line. Be sure to test whether a file open succeeds or not and close any file you open when done.

Python programming help  I need help of question 1 to read a file from persons.txt   Write a program that takes a person’s details (name, age and a city), and writes to a file (persons.txt) using a loop repeatedly. You should write three person’s to the file. The program terminates on entering any key by the user, except on (Y or y) key.  Sample output of the first run of the program is shown below:              Enter name: JohnEnter age: 20Enter city: SydneyData saved:  John 20 SydneyPress (Y or y) to add another person, or any key to exit    Question 1) Write a program that read a file (persons.txt) from previous question given on the top of this question, and shows all the records/lines from the file as a nicely formatted report with a header as shown:    Name                   Age                      City   +---------------------+--------------------+--------------
