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.
Write a function that receives an integer. The function must return a string containing thehexadecimal representation of the integer.
In C++, write a function isVowel that returns true if a character is a vowel (whether you want to include 'y' as a vowel or not is up to you) and false otherwise. Use this function in a program that asks the user to enter a string of characters and outputs the number of vowels.

The program then uses the function substr to remove all the vowels from the string. For example, if str = "There", then after removing all the vowels, str = "Thr". After removing all the vowels, output the string. Your program must contain a function to remove all the vowels and a function to determine whether a character is a vowel.arrow_forwardWrite a function that returns the common characters of two strings using the following header: string commonChars(const string& s1, const string& s2) Write a test program that prompts the user to enter two strings and display their common characters.

- write a c++ code in which : Q2: Write a function that, when you call it, displays a message telling how many times it has been called: “I have been called 3 times", for instance. Write a main() program that calls this function at least 10 times. HInt: use a global variable to store the countarrow_forwardQ5. Write a function called findString to determine if one character string exists inside another string. The first argument to the function should be the character string that is to be searched and the second argument is the string you are interested in finding. If the function finds the specified string, have it return the location in the source string where the string was found. If the function does not find the string, have it return -1. For example: For function, findString ("a chatterbox", "hat") It searches the string "a chatterbox" for the string "hat". Because "hat" does exist inside the source string, the function returns Location= 3 to indicate the starting position inside the source string where "hat" was found. Programming Language :- C Note: You are not allowed to use inbuilt string library functionarrow_forward4. Complete the function show_upper. This function takes one parameter - a string (s). It should return a string made up of all the upper-case characters in s. For example, if s is “aBdDEfgHijK” then show_upper should return “BDEHK”. It should return the upper-case string - not print it. Do not change anything outside show_upper.arrow_forward
- Write a function that prompts the user to input a sentence. Then checks the sentence to make sure the following rules have been followed: • the entire first word of the sentence should be capitalized • the sentence ends with a punctuation mark (any) If the sentence meets these requirements, print and return the string RULES CONFIRMED (exactly as shown). If the sentence does NOT meet the requirements, the function should fix the sentence such that it will pass the rules, print the type of error(s) and then return the fixed sentence. Examples Examples of function being called fixer ("THIS is a test?") Example of function output RULES CONFIRMED ERROR: First word is not translate ("this is capitalized a test") ERROR: Missing ending punctuation mark translate ("THIS is ERROR: Missing ending a test") punctuation mark translate ("This is First word is not a test!") capitalized Example of string returned by function RULES CONFIRMED THIS is a test.
