Write a program that reads a text and outputs the letters, together with their counts, as explained below in the function printResults. Your program should not have any global variables. All information should be accessed through the parameters of the functions. Your program should have the at least the following functions: • Function main – calls all the functions • Function openFile – opens the input and ouput files. This program has the file stream declare a refence parameter. An appropriate error message should be displayed if the file does not exist. The program must ask the user for the names of the input and output files. • Function countLetters – counts every of uppercase letters A – Z and lower-case letters from a – z in the text file opened in the function openFile. This information should be stored in an array of structures. Both the array and file identifiers must be passed as parameters. • Function printResults – prints the number of uppercase letters for every occurrence of A–Z and the percentage of lower-case letters for every occurrence of a–z. The percentage should look like this: “25%”. This information must come from an array of structures, and must be passed as a parameter.
Write a
below in the function printResults. Your program should not have any global variables. All
information should be accessed through the parameters of the functions. Your program should
have the at least the following functions:
• Function main – calls all the functions
• Function openFile – opens the input and ouput files. This program has the file stream
declare a refence parameter. An appropriate error message should be displayed if the file
does not exist. The program must ask the user for the names of the input and output files.
• Function countLetters – counts every of uppercase letters A – Z and lower-case letters
from a – z in the text file opened in the function openFile. This information should be stored
in an array of structures. Both the array and file identifiers must be passed as parameters.
• Function printResults – prints the number of uppercase letters for every occurrence of A–Z
and the percentage of lower-case letters for every occurrence of a–z. The percentage should
look like this: “25%”. This information must come from an array of structures, and must be
passed as a parameter.
