counting the number of times each character occurs in a .txt file

This project will “analyze” the input data (a file of characters) and count the number of each character in the file. You have one input file, data.txt. Make sure that your file has a newline character after the last (visible) character entered in each file. The file will be attached to this project bid. Each file contains text. You do not know how many characters appear in each file, but any character listed in the ASCII table is possible. (You can ignore space characters.) At the end of the file, your program should show the 5 most common characters in the file, and the count and percentages of those 5 characters. This output should be formatted in columns, as shown in the sample output below. Also, list the “printing” characters which were never used in the file. (“Printing characters” are numbered from 33 to 126 in the ASCII table. You should ignore other characters.)This project requires you to use at least 2 functions in addition to the main() function. If you could use “casting” variables from char to int (“int(ch)”) or from int to char (“char(x)” that would be great! you can only use: if statements, loops, nested loops, functions,arrays, and switch statements. CANNOT USE STRINGS,VECTORS,ETC. the headers should only be #include<iostream>, #include<fstream>, using namespace std; Then your 2 function declarations. Then the main(). Then the 2 function definitions. The way the output should look is attached and the txt file is also. If you use Linux and cannot open the word document, then go to [login to view URL] The picture of how the final output should look is there.
