Write a C function willH dle int copyFile (char filenamel, char filename2); Siven the names of a destination and of a source file (respectively, filenamel and filename2), the function should copy the content of the sourc nto the destination file, after transforming the alphabetic characters from lowercase to uppercase and vice-versa (all the other characters are copiec s they are). In case the copy operation is not successful, the function should return the value-1. Otherwise, it should return the total number of naracters that were successfully copied.

Project 8 Specifications Using OOP, write a C++ program that will read in a file of names and a file of birth years. The file of names is called Names.txt and the file of birth years is called BirthYear.txt. Both input files should be located in the current directory of your program. The list of names in the Names.txt file corresponds to the list of birth years in the BirthYears.txt file. This means:The first name in the names.txt file corresponds to the first birth year in the birthyear.txt file. The second name in the names.txt file corresponds to the second birth year in the birthyear.txt file...and so on.Read in and store the names into an array of 30. Next read in and store the birth years into another array of 30 integers.Sort the arrays using the selection sort or the bubblesort code found in your textbook. List the roster of names in ascending alphabetical order displaying their birth years beside their names.Next, prompt the user to enter a birth year. Validate this…
****IN PYTHON! Write a function named file_stats that takes one string parameter (in_file) that is the name of an existing text file. The function file_stats should calculate three statistics about in_file: the number of lines it contains, the number of words and the number of characters, and print the three statistics on separate lines. For example, the following would be the correct input and output:>>> file_stats('created_equal.txt')lines 2words 13characters 72Note: The number of characters may vary slightly between operating systems. Similarly, the number of lines may vary by 1 line, depending on the method used to calculate it. I attached a picture of my code so far and a picture of what the text file reads.
Problem 5 Solve this problem inside the files problem5-library.c and problem5-library.h. Do not modify any other files for this problem. Write a function called "nextLetter" inside problem5-library.c and add its prototype inside problem5-library.h. • The function must accept 2 parameters, a character then an integer. It will return a character. • The function will return the character that is reached by starting from the passed letter and moving steps equal to the passed integer. Check the examples below: Example: If the parameters were 'A' and 1, the function will return 'B', because 'B' is 1 step away from 'A'. Example: If the parameters were 'e' and 3, the function will return 'h', because 'h' is 3 steps away from 'e'. • If the given letter is uppercase, the returned letter must be uppercase. If the given letter is lowercase, the returned letter must be lowercase. • If the given integer is too big or will cause the letters to reach the last letter, you must restart the letters from…
2. hello world Write a hello.c file that contains two functions. The function sayHello should take a single string (char *) parameter and write the message "hello" followed by the value passed in. So if you call sayHello("world"), the result should print hello world You should use printf to do the printing. The function main should call sayHello("world") as its only work. Make sure your hello can be compiled all the way and correctly runs. Generate hello.s and comment it as above. Note that the compiler can do some different things for main.
