I need a C++ coder for some simple programs...filechecker

#1 I need a C++ program that will open a file and re-write that file with all the spaces between the words being single. So if the file has 2 or more spaces I would like for it to change it back to one space between each word with the output written to a file called output.txt. #2 Then I would like a program that merges the numbers in two files and writes all numbers into a third file. The program takes input from two different files and writes output to a third file. Each input file conatains a list of numebers of type int in sorted order from the smallesr to the largest. After the program has run, the output file will conatain all the numbers in the two input files in one longer list in sorted order from smallest to largest. Define the program as in a way that the function is called from two input streams and the output file stream as three arguments. 3# Finnally I need a program that computes numeric grades for a [login to view URL] course the corse records are in a file for input. The input file contains : stadents Last Name then a spacethen stdent's first name the a space the 10 quize scores all with one space and all this on one line.(Whole numbers only). The program will take input from this file and send it to an output file but the output file will contain an additional number at the end of each line. Which wil be the average of each student's grades ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. This only a book assignment but I need tutoring from experts and must be able to see working programs. ## Deadline information None.... I just have to learn programming in reverse
