Exercise 1: Word Separator Write a program that accepts as input a sentence in which all of the words are run together, but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example the string StopAndSmellTheRoses. would be converted to “Stop and smell the roses.” Exercise 2: replaceSubstring Function Write a function named replaceSubstring. The function should accept three 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…
3. Word Counter Write a function that accepts a pointer to a C-string as an argument and returns the number of words contained in the string. For instance, if the string argument is "Four score and seven years ago" the function should return the number 6. Demonstrate the function in a program that asks the user to input a string then passes it to the func- tion. The number of words in the string should be displayed on the screen. Optional Exercise: Write an overloaded version of this function that accepts a string class object as its argument.

Homework 10-1 Programming Challenge: 2 - Backwards String Write a function that accepts a string and returns a string in which the contents are the reverse of the original string, and a program in which this function is demonstrated. The prototype is string reverseString(const string &); This might need a little explanation. We want to pass the string by reference (as is customary for objects) but we don't want the function to make any changes to our string. Thus, we pass as a "constant reference." Newer languages like Java do this automatically; if you pass an object to a Java method, it's handled internally kind of like this, as a constant reference to that object. Any changes made to the object within the function are strictly local; the original object is unchanged. So our function will return a brand new string with contents equal to the reverse of the string sent to the function.
Count Vowels Write a function called count_vowels that accepts a string argument that represents a word and returns the number of vowels that are in the word. The vowels are A, E, I, O, and U (ignore the 'sometimes Y' rule). Count both uppercase and lowercase vowels. 1
10. Exercise 9 - Strings (Assessed Exercise) Important: Do not attempt this exercise before completing Exercises 6, 7 and 8. Think how to reuse the functions you created in Exercises 6, 7 and 8. Design and Problem Solving: Create an algorithm for a program that reads a string with a maximum length of N from the keyboard (N should be specified by the user). N should not be more than 100. The algorithm should then copy the characters from that input string into a second character array (in the order of input). However, a character will be copied into the second array only if it is a vowel (i.e., a, e, i, o, u). This second array should be allocated dynamically and its size will depend on the number of characters that will be copied into it. Murdoch UNIVERSITY Once copied, the algorithm should output the values stored in the second string. The algorithm should then count and display the number of times each vowel appears in the second array. Also, the algorithm should determine and output…
longest.py -> using sys.argv ● Create a program, longest.py, that has a function that takes one string argument and prints a sentence indicating the longest word in that string. If there is more than one word print only the first. Your print statement should read: “The longest word is x” Where x = the longest word. The word should be all lowercase.
shortest.py • Create a program, shortest.py, that has a function that takes in a string argument and prints a sentence indicating the shortest word in that string. If there is more than one word print only the first. Your print statement should read: "The shortest word is x" Where x = the shortest word. The word should be all uppercase.
3. Complete the function count_digits. This function takes one parameter - a string (s). It should return the number of digits in s. For example, if s is "25 or 6 to 4 is a song by Chicago" then count_digits should return 4. count_digits should not print the result- it should return it. Do not change anything outside count_digits. Save & Run Load History Show CodeLens 1 def count_digits(s): 2 ''Returns the number of digits in s''" 3 pass #Hint: make a string of digits to use #in checking whether each character #is a digit.

Learning Objectives: Python Programming Use loop over a stringReplace characters within a stringFunction (declaration and call)Write code in modular formInstructions Create a function only_chars that takes the line of text and returns the text line excluding the spaces, periods, exclamation points, or commas. Create a program that will read the input line, use the function, and then print the line, without spaces, periods, exclamation marks, or commas and their length. Ex: If the input is: Listen, Mr. Jones, calm down. the output is: ListenMrJonescalmdown21Do not forget if __name__ == "__main__" section!
countVowels.py● Using import sys : Create a python program called countVowels.py that has a function that takes in a stringthen prints the number of unique vowels in the string (regardless of it being upperor lower case).● For example:○ The argument “swEet” should print 1○ The argument “AaaaeeE” should print 2
