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.

1. Write a function num_double to read file (f1.txt), double all the numbers, keep the string (no change), and write to another file (f2.txt), for example: >>># f1.txt-“I have 5 books and 3 pens...” >>> f2 = num_double(f1) >>> # f2.txt – “I have 10 books and 6 pens ...”
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.
Question B. Write a C++ program that reads the marks of a group of students from a text file "grades.txt" and computes the average of all grades.

Write a C program named toupper.c that reads the contents of a file, and writes to another file after changing all lowercase letters in the input file to uppercase. The name of the input file and the output file are to be passed as command line arguments. Assume there are only ASCII characters in the input file. The length of the input file is not known beforehand. So make sure your program keeps reading bytes until EOF is reached. Use the library function toupper to concert letters into uppercase. Example: The program is run from the command line as follows; C:\>toupper.exe infile.txt outfile.txt Suppose the contents of the input file infile.txt is: AbcdefG The contents of the output file outfile.txt should be: ABCDEFG
Implement a function wordCount, which reads a text file, and returns thenumber of words in the file. You can assume the file only contains thealphabet characters and the space character. However there may be morethan one space character between two words, so “abc abc” and “abc abc”,for example, are both two words. int wordCount ( const char * filename ) {}
You are given a file consisting of students’ names in the following form: lastName, firstName middleName. (Note that a student may not have a middle name.) Write a program that converts each name to the following form: firstName middleName lastName. Your program must read each student’s entire name in a variable and must consist of a function that takes as input a string, consists of a student’s name, and returns the string consisting of the altered name. Use the string function find to find the index of ,; the function length to find the length of the string; and the function substr to extract the firstName, middleName, and lastName.
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
1. Given two .txt files that have lists of numbers in them, find the numbers that areoverlapping (print them in the output). “primenumbers.txt” has a list of all primenumbers under 1000, and the other “happynumbers.txt” has a list of happy numbersup to 1000.We can divide this problem into different parts:a. Write a function (call it readFile) that takes the name of a file as argument and read the content of the file and store it in a list (each line contains onenumber, so each number is stored in the list) and return the list.b. Write a function that takes two lists and return another list containing thecommon elements of two lists (you have written this function before! You canuse it)c. Write a function (call it writeFile) that takes a list and name of a file. The function should write the content of the list in the file (each element in oneline).d. Use the above functions to do the task of this lab.
python Write a function that reads in a text file, and counts the number of times each word occursin the file. Then print the words alphabetically with its corresponding count. Each word willbe separated by a space or newline, but there is no guarantee that each word will be on aseparate line.
