Chapter 8.1, Problem 4STE
Suppose the function strlen (which returns the length of its string argument) was not already defined for you. Give a function definition for strlen. Note that strlen has only one argument, which is a C string. Do not add additional arguments; they are not needed.

Write in C++
Write a function called charCount() that takes a string as an argument. Count the number of occurrences of each character in the string and print the characters and their counts in alphabetical order (first uppercase and then lowercase) if they occur at least once in the string. Return the number of unique characters in the string (capital and lowercase are considered different).
Function specifications
Name: charCount()
Parameters (Your function should accept these parameters IN THIS ORDER):
input_text string: The text string containing characters between A to Z and a to z
Return Value: int: The number of unique letters in the input string
The function should print the number of occurrences for every letter that appears at least once in the input string, beginning with capital letters.
Hint: Create an integer array (or multiple arrays) where each element represents the number of occurrences for every letter. Iterate over characters in the string, incrementing the…
A function that turns an argument to a string (call it “toString(…)”) is a great use of function overloading. In one sentence, why might this be?
In one sentence, why should we generally verify the arguments are what we expect when writing a function?
1- Write a function that takes a word less than 25 characters long and returns the letter that
word starts with (in capital letters).
Frank starts with the letter F.
2- Write a function that has a string as formal parameter. The function then replaces all spaces
and punctuation marks in the string with the asterisk (*). Here is a sample run:
Nothing is impossible, the word itself says 'I'm possible'!
Nothing*is*impossible**the*word*itself*says**I*m*possible**
3- Write a function that takes as input one line and reverses the words of the line.
For example,
birds and bees
Reversed: bees and birds
4- Write a function that takes nouns (a string) as inputs and forms their plurals based on these
rules:
a. If noun ends in "y", remove the "y" and add "ies".
b. If noun ends in "s","ch", or "sh", add "es".
c. In all other cases, just add "s".

- Solve the problem in C++ (Anagrams) Write a function that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, “silent” and “listen” are anagrams. The header of the function is as follows: bool isAnagram(const string& s1, const string& s2) Write a test program that prompts the user to enter two strings and checks whether they are anagrams. Sample Run 1 Enter a string s1: silent Enter a string s2: listen silent and listen are anagrams Sample Run 2 Enter a string s1: split Enter a string s2: lisp split and lisp are not anagramsarrow_forwardWrite a function findLetter based on the following rules: It takes a string named str and a character named ch as parameter, returns the index of the first occurrence of the character ch if the str string contains the character ch; If the relevant character is not found in the string, write a function that returns -1. Call the function inside the main function and test it. You should use the prototype given below:arrow_forward3. Experiment with the following code for different strings assigned to s: S = # yourstring goes here for c in s: if c.isupper () : print (c) 4. Write a function upper that behaves as follows, i.e. it returns the substring of capitalized letters.arrow_forward
- Write a function findFirstUpper() that takes a string as parameter, finds returns the index of the first uppercase letter in the string. If there is no uppercase letter in the string, then the function will return -1.Example: Function call findFirstUpper("best course is CS104!") will return 15 (index of the 'C').Example: Function call findFirstUpper("good morning!") will return -1.

- Please include doctring and write this in python only. Write a function named words_in_both that takes two strings as parameters and returns a set of only those words that appear in both strings. You can assume all characters are letters or spaces. Capitalization shouldn't matter: "to", "To", "tO", and "TO" should all count as the same word. The words in the set should be all lower-case. For example, if one string contains "To", and the other string contains "TO", then the set should contain "to". You can use Python's split() funciton, which breaks up a string into a list of strings. For example: sentence = 'Not the comfy chair!' print(sentence.split()) ['Not', 'the', 'comfy', 'chair!'] Here's one simple example of how words_in_both() might be used: common_words = words_in_both("She is a jack of all trades", 'Jack was tallest of all')arrow_forward10.

- This is for my C++ 2 class, so still a beginner C++ program: Case Manipulator Write a program with three functions: upper, lower, and flip. The upper function should accept a C-string as an argument. It should step through all the characters in the string, converting each to uppercase. The lower function, too, should accept a pointer to a C-string as an argument. It should step through all the characters in the string, converting each to lowercase. Like upper and lower, flip should also accept a C-string. As it steps through the string, it should test each character to determine whether it is upper- or lowercase. If a character is uppercase, it should be converted to lowercase. If a character is lowercase, it should be converted to uppercase. Test the functions by asking for a string in function main, then passing it to them in the following order: flip, lower, and upper.arrow_forwardCreate a function called reverse() that has a string parameter. The function reverses the characters of the string locally. ( in C language)arrow_forwardWrite a function named replaceSubstring. The function should accept three C-string or string object arguments. Let’s call them string1, string2, and string3. It should search string1 for all occurrences of string2. When it finds an occurrence of string2, it should replace it with string3. For example, suppose the three arguments have the following values: string1: "the dog jumped over the fence" string2: "the" string3: "that"With these three arguments, the function would return a string object with the value “that dog jumped over that fence”. Demonstrate the function in a complete program.arrow_forward
