Question

You are given a text file containing a short text. Write a program that

1. Reads a given text file : shortText.txt

2. Display the text as it is

3. Prints the number of lines

4. Prints the occurences of each letter that appears in the text. [uppercase and lowercase letter is treated the same].

5. Prints the total number of special characters appear in the text.

6. Thedisplayofstep3,4and5aboveshouldbesaveinanoutputfile:occurencesText.txt

write it in C++ programing Language

Answer 1

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
=================================

// shortText.txt (input file)

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 CAT computers very flexible and useful.
Since ancient times simple CAT 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.
