- Objective: string and character manipulation, string.h and ctype.h libraries For each of the problems, create a user-defined function. Then write a driver program for the functions inside the main. 1- Write a function that takes a word less than 25 characters long and returns the letter that word starts with (in capital letters). 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 (*). 3- Write a function that takes as input one line and reverses the words of the line 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”. Now create the driver program - Ask the user for their first and last name. Store the names in separate arrays. - Greet the user by their full names. - Let them know what their…Write a function that reverses a string. The header of the function is: def reverse(s):Write a test program that prompts the user to enter a string, invokes the reverse function, and displays the reversed string.JS Write a function named "tweets" that takes a string as a parameter. If a message can hold at most 280 characters, calculate the smallest number of messages needed to hold all of the text in the input. The function should return the number it calculated.
- Write the countVowels function which counts the number of vowels using the string class as follows: int countVowels(const string& s) Write a test program that prompts the user to enter a string, invokes the countVowels function and displays the total number of vowels in the string.3. String (a) Write a Python function that accepts a string s and an integer n with a single digit (i.e., 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9) as its arguments, and returns a new string that replaces every digit n found in s by a new digit that equals to (n + 1) %10. The function returns an empty string if n is not a single digit integer or is negative. COMP132 Assignment #2 replace_string("He330", 3)-> "He440" "He331" replace_string("He330",0)-> replace_string("He330",-4) replace_string("He330", -> 12)-> 11 11 11 11 (b) Write a Python function that accepts a string as the argument, moves the first 3 characters of the string to the end, and prints it out. If the length of the string is less than 3, your function should print an error message. move_string ("Hello") ->loHel move_string ("Hi, My name is Mark.") -> My name is Mark. Hi, move_string ("Hi")->Invalid StringPYTHON Problem Statement Implement a function which takes two arguments: the first is a string and the second is a single character (as a string). This function should move every instance of the given character in the string to the end of the string, and then return (do NOT print) the final string. NOTE: Only write code within the function. You do not need to utilize the "input()" function. The autograder passes inputs directly to the function as arguments, and the checked output is the returned value from the function. Sample Input "hello how are you?", "o" Sample Output "hell hw are yu?ooo" Starter Code def move_character(word, character):
- // write a function that takes the input string and reverses it// example// argument: Hello// return: olleHfunction reverseThisString(string){ } // write a function that takes the input string and switches all uppercase characters to lowercase and lowercase charcaters to uppercase// example:// argument: Hello World// return: hELLO wORLDfunction swapCase(string) { } //convert array of numbers from farenheit to celcius// example:// argument: [23, 32, 41, 50, 59]// return: [-5, 0, 5, 10, 15]// hint: use Array.mapfunction toCelcius(array){ } //write a function that takes an input array and returns an array of booleans (>=75) or fail (<75)// example:// argument: [20, 30, 50, 80, 90, 100]// return: [false, false, false, true, true, true]// hint: use Array.mapfunction passOrFail(array){ } //write code that loops through the two variables returns an array ['2 is zwei', '3 is drei', '4 is vier', '5 is fünf', '6 is sechs']// example:// return: ['2 is zwei', '3 is drei', '4 is vier', '5 is…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. 1uctirst(); function: O a. converts all letters into upper case O b.converts first letter into uppercase Oc. converts first letter into lower case O d. converts all letters into lower case t of
- 8. Sentence Capitalizer Write a program with a function that accepts a string as an argument and returns a copy of the string with the first character of each sentence capitalized. For instance, if the argu- ment is “hello. my name is Joe. what is your name?" the function should return the string "Hello. My name is Joe. What is your name?" The program should let the user enter a string and then pass it to the function. The modified string should be displayed.Instructions The python "try" keyword is very powerful in that it can, among other things, prevent a program from ending abnormally because of invalid numeric input. Write a python program with two functions/modules that does the following: .main() accepts input and calls a function to test if the input is a number and displays a message regarding the result of that numeric test • numTest() is passed an input string, tests to see if the string is numeric and returns the necessary information to main() . a NULL input (just pressing the enter key) ends the program . DO NOT USE THE BUILTIN PYTHON FUNCTION FOR NUMERIC TESTING Be sure to use clear prompts/labeling for input and output.Programming language: SWIFT Write a function that takes a string as a parameter and returns the string "Swift" if the string passed as parameter begins with "SWIFT" or "swift". Otherwise, returns an empty string.
