- (Program) Using the at() function, write a C++ program that reads in a string by using getline() and then displays the string in reverse order. (Hint: After the string has been entered and saved, retrieve and display characters, starting from the end of the string.)Q3: Write a complete C++ program that contains the integer functions (main, funx and funy). The main function declares an integer (k), which is assigned a value using cin. Then print funx(k), where funx(n)=2*funy(n-1) if n >1 and funx(n)=1 if n1 and funy(n)=1 if nQ3: Write a complete C++ program that contains the integer functions (main, funx and funy).

- Write a C function countDigits() that takes a string as parameter, finds and returns the number of numeric characters ('0', '1', ... '9') in the string. Prototype: int countDigits(char str[]);Write a function that is given two strings as parameters and returns the concatenation of these strings (you are not allowed to use strcat() or similar functions: work low level with loops (while/for)). (in C language)The question should be done in C++, please give explanation and running result. 1. Let’s write a function that compares 2 strings and returns true if they were identical, false otherwise. The signature of this function should be: bool word_diff(std::string word1, std::string word2); For example: std::string str1 = "Hello World";std::string str2 = "hEllO World";std::string str3 = "World";std::string str4 = "Hello World";bool result = word_diff(str1, str2); // Falsebool result = word_diff(str1, str3); // Falsebool result = word_diff(str1, str4); // True 2. Now let’s follow a classical approach to compare the content of 2 files. We should open each file, read their content word by word and compare them until a first mismatch occurs.Let’s implement a function called classical_file_diff that takes 2 arguments each of which is a file name and returns a boolean indicating whether the 2 files are identical or not. The signature of this function should be: bool…
- Write a function in C++ that outputs a string of a character using setfill. Test it 3 times within the code different characters and string lengths.you will develop a string-reversing c++ program using functions. You will need to create a function str_rev() that takes a parameter of string type as the input and returns the reversed string.Write a C program that converts an uppercase character to alowercase character. Declare functionchar toLower(char ch);to do the conversion. If ch is not an uppercase character, thefunction should return ch unchanged. If it is an uppercasecharacter, add the difference of 'a' and 'A' to ch as the return value
- Write a C++ function that accepts a double typed number and return back the fractional part of the number. For example, if the number is 789.123, the number 0.123 should be returned.You must answer 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 anagramsWrite a c++ function called validate that takes a string and validates that the string does not contain any numbers, then outputs whether the string is valid or not. Write a code that tests the function, by taking the string as an input.
