Question

please use c++

please write down the input file information

please add comments for some codes

please do not use #include <bits/stdc++.h> we did not learn it yet

thank you

CSIT 575-Take Home Lab #11: Arrays To learn to code, compile and run a program processing characters. Assignment Plan and code a top-down modular program utilizing ARRAYS to solve the following problem, using at least 3 functions (called from the main() section or from another function) to solve the problem. Write a program that anlyzes text and counts the following number of lower case letters number of uppercase letters number of spaces number of punctuation characters Total number of all letters e Total number of all words Number of occurrences of each letter (chart, see below) Input Characters, one at a time, from a text-file. Create the data file below in text editor or Notepad All components of an array must be of the same data type; while not extreme, this is a serious limitation since there are many situations in which this is not possible. Fortunately, most programming languages provide another structured data type, structures, which allow heterogeneous information to be stored, accessed, and manipulated. A structure contains fields, which can be of different data types. Output The number of occurrences of each alphabetic character, the number of lower case and upper case letters, the number of spaces, the number of punctuation characters, the number of words and a chart of the number of occurrences of each letter. So output should look something like this (the data is just guesstimating, not actual answers) Number of upper case letters Number of lower case letters 150 Number of spaces: 75 Number of punctuation characters 12 Total number of all words: 57 Number of occurrences of each letter (A or a, B or B.. .Z or z) A/a: 17 C/c: 8 Y/y: 3 z: Top down design with parameters, program listing, and program output with comments and/or pseudocode.

A computer is a device that can be instructed to carry out an
arbitrary set of arithmetic or logical operations automatically.
The ability of computers to follow a sequence of operations
called a program make computers very flexible and useful.
Since ancient times simple manual devices like the abacus
aided people in doing calculations. Early in the Industrial
Revolution, some mechanical devices were built to automate
long tedious tasks, such as guiding patterns for looms.
