3. Write a program that reads integers from a file, sums the values and calculates the average. a. Write a value-returning function that opens an input file named inFile.txt. You may "hard-code" the file name, i.e., you do not need to ask the user for the file name. The function should check the file state of the input file and return a value indicating success or failure. Main should check the returned value and if the file open fails, output a message to cout and exit the program. b. Write a void function that reads the integers from the data file, sums the values and calculates the average of the values. Return the sum of the values, number of| values read and the average of the values to the calling module, main. Since you do not know the number of values in the file, you must check for end of file. c. In main, output to cout the sum, number of values read and the average. d. Include the function prototypes e. Declare the variables necessary to create a running program. f. Write statements for all include files, using statements and main.

(5) Write a function called copy_even_lines() that takes two strings (filenames) as input parameters and copies every other line from the first file into the second. That is, counting from 0, it copies the 0th line, the 2nd line, the 4th line, etc. from the first file to the second file. You may assume that both files exist. (6) Write a python program that asks the user for two filenames and calls your function copy_even_lines() from (5) using those two filenames. If one or more files do not exist, your program must handle the exception by repeating the prompts until valid filenames are entered.
Write a function that reads a single line of numbers from a file named "question1.txt", and returns the average of the numbers read. For example, if the file is as follows: ----- question1.txt -----1 3 5 -2 4 0 6 -2 -3------------------------- then the function must return 12/9 = 1.33333

Using Programming C++..... a) Write a program that reads a text file in which each line in the file consists of a first name, a last name, following by 4 grades (double types) like Tim Hanes 78.3 98.0 80.5 72.3 The program must read every line of the text file, find the average of the 4 grades then print the names followed by the averages (one name per line) in a second file as well as on the monitor. b) Create the text file with at least 5 entries with the format given in part (a). Give the absolute path of the file in your computer. Test your program in part 2(a) on this file.
Write a function count_character(filename, character) that takes in a filename and a character, both as strings, and returns the total number of times the given character occurs in the file. Examples: Contents of hello.txt:HelloHELLOHelloHELLO count_character('hello.txt', 'L') returns 4count_character('hello.txt', 'H') returns 4count_character('hello.txt', 'e') returns 2 Requirements: Please use Python Programming only Show screenshot of your work.
Write a function void saveByDept(char *fileName, char *deptName , student allStudents[], int size) that will save the information of all students who belong to the department with name pointed to by deptNameinto a text file. The name of the file is given as an input parameter, fileName
You are creating a function that reads a data file and prints each line of the file. You write the following code. Line numbers are included for reference only The code attempts to read the file even if the file does not exist. SEE PHOTO You need to correct the code. Which three lines have indentation problems? Each correct answer presents part of the solution. (Choose three.) Group of answer choices Line 04 Line 03 Line 05 Line 02 Line 06 Line 07 Line 01 Line 08
Write a program that computes and prints the average of the numbers in a text file. You should make use of two higher-order functions to simplify the design. Ask the user for the name of the .txt file that contains the list of numbers. Include your code as usual in a .txt AND .py file. Create and use a .txt file to test your code using the numbers 78, 54, 22, 90, 15, 7.
Question 55 Write a function that takes two parameters, a file name to create and an integer. The function should write all the even numbers between 0 and the integer to the file name passed in. The numbers should be all on one line of the file For example: write_evens("even_file.txt",20) This should create a file called even_file.txt that contains 0 2 4 6 8 10 12 14 16 18 20 Full explain this question and text typing work only thanks
3. Write a function which reads an already existing file “File1.txt” and write digits (0-9) in to a new text file “mynumber.txt” and non digits into a file “Text.txt”.in c++
Write a small program that copies everything in a tet file to another file. The text file is calledin.txt and the output file is called out.txt. Two files should be exactly the same after copying(the first file shouldn’t be changed, and the second file should be the same as the first one).Your program should define a function called copyFile to copy the input file to the output filewith two arguments: a file pointer to the input file and a file pointer to the output file. You shouldnot and do not need to use an array during copying.
