This assignment aims to assess your skills$/$knowledge on basics of String creation and various string handling functions. This is a scenario based practical assignment to create a text analysis tool, providing students with a hands$-$on opportunity to apply their programming skills in a real$-$world context. The assignment focuses on developing a program that performs various operations on text input, enhancing students' skills in handling strings, data analysis, and user interaction.

Scenario: You have been asked to create a text analysis tool that will perform various operations on a given text input. This tool will help users gain insights into the text data by performing character and word analysis.$$

Assignment Tasks:$$

$1.$ User Input: Ask the user to input a paragraph or a lengthy text. Your program should read and store this input.$$

$2.$ Character Count: Calculate and display the total number of characters in the input text.$$

$3.$ Word Count: Calculate and display the total number of words in the input text. Assume that words are separated by spaces.$$

$4.$ Most Common Character: Find and display the most common character in the text. In case of a tie, select any of the tied characters.$$

$5.$ Character Frequency: Ask the user to input a character. Check and display the frequency of occurrences of this character in the text. Be case$-$insensitive $($e$.$g$.,\text{'}$a$\text{'}$ and $\text{'}$A$\text{'}$ should be considered the same character$).$

$6.$ Word Frequency: Ask the user to input a word. Check and display the frequency of occurrences of this word in the text. Be case$-$insensitive.$$

$7.$ Unique Words: Calculate a

You will be assessed based on the following criteria:

$1.$ Compilation $$ The code runs without any errors.

$2.$ Input Validation $$ This ensures that the user's input meets certain criteria or constraints before it is processed further.

$3.$ Logic and Computation $-$ This handles the core functionality and processing of the questions.

$4.$ Program flow and structure $-$ It encompasses the overall structure and behavior of the program.

$5.$ Submission of code and screenshots of the output.

$6.$ Code style and readability $-$ Refers to the way the code is written, organized, and presented. It focuses on making the code clear, easy to understand, and maintainable.
