Part 1: Text Surgeon Problem statement: You are tasked to write a program that reads in a sentence or a paragraph (max length 1023 letters) from the user, store it as a C-style string. Then the program gives the user several options for operations to perform on the text or quit. After performing an operation, the user should be prompted to select another option to operate on the original string until they select the option to quit. The program must handle all types of bad inputs from the user and recover from the errors. Detailed requirements for each choice are listed below: 1. Letter swap: the user inputs two letters, and the string is modified to replace all first letters in the text with the second letter. Example: User enters "off we go, into the wild blue yonder!", then characters 'o' and 'i'. Program modifies the string to: Iff we gi, inti the wild blue yinder! (Note: capitalization is preserved) 2. Flip (reverse) the string: For this option, you need to create a new c-string from the heap, with exactly the size of the user's input string (not the max length 1023!), and then reverse it. Remember to clean up your heap! Example: User enters "ban ana54!"; program creates a new string and outputs: "!45ana nab" Example: User enters "zip"; program creates a new string and outputs: "piz" 3. Words frequency: Prompt the user for an integer N, which represents for N words that the user wants to search for in the input string. Then prompt the user for these N words. Use a dynamic C++ string array allocated on the heap to store N words and output the frequency of each given words in the input string. Example: User enters "This is a test sentence, is this?", then 3 words, "this", "text", and "test". The program outputs: this: 2 text: 0 test: 1 (Note: Case insensitive, which means "word" and "WORD" are the same; All numbers and special characters in the string are ignored, which means "wor32rd", "wo]]]rd343.34", and "word" are the same) Suggested functions: a. char * purge_string (char *str); llaccepts a c-string, and returns a version where all numbers, spaces, and special characters removed (Note: the returned c-string must be on the heap, otherwise this c-string will be deleted once we leave this function) OR you may use this:
