Complete the isFloat() function which returns true if a token represents a floating-point number. This is a little more difficult than isInt. The token "42" should return false, while "1.5" and "2e3" should return true. #include #include #include using namespace std; bool isFloat(const string& token) { ... }

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 anagrams
The international standard letter/number mapping for telephones is: Write a function that returns a number, given an uppercase letter, as follows:def getNumber(uppercaseLetter):Write a test program that prompts the user to enter a phone number as a string. The input number may contain letters. The program translates a letter (uppercase or lowercase) to a digit and leaves all other characters intact. Here is a sample run of the program: Enter a string: 1-800 flowers1-800-3569377
Complete the Swap() method in main.c to exchange the values of the num field of two Number struct objects, num1 and num2. Hint: Refer to the given Number struct to see the num data member. Ex: If num1 is 19 and num2 is 178, calling Swap(num1, num2) will swap the values so that num1 becomes 178 and num2 becomes 19.
Write a function that when given a URL as a string, parses out just the domain name and returns it as a string.

solve in C please. Implement the following two functions that get a string, and compute an array of non-emptytokens of the string containing only lower-case letters. For example:● For a string "abc EFaG hi", the list of tokens with only lower-case letters is ["abc", "hi"].● For a string "ab 12 ef hi ", the list of such tokens is ["ab","ef","hi"].● For a string "abc 12EFG hi ", the list of such tokens is ["abc","hi"].● For a string " abc ", the list of such tokens is ["abc"].● For a string "+*abc!! B" the list of such tokens is empty.That is, we break the string using the spaces as delimiters (ascii value 32), and look only at thetokens with lower-case letters only .1. The function count_tokens gets a string str, and returns the number ofsuch tokens.int count_tokens(const char* str);For example● count_tokens("abc EFaG hi") needs to return 2.● count_tokens("ab 12 ef hi") needs to return 3.● count_tokens("ab12ef+") needs to return 0.2. The function get_tokens gets a string str, and…
Write a program to reverse the words of a string. Implement a function reverse () that reverses the string between indexes i and j inclusively. Prototype of the function is given below. void reverse (char *str, int i, int j)
Task 2: Implement the function Searchingstrings that allow to search a sub-string in a given string and display the: First occurrence, Last occurrence, First occurrence from a given index and Last occurrence from a given index. You can use the following String methods: string. IndexOf(searchvalue, start) return the position of the first occurrence of specified character(s) in a string. string.lastIndexOf(searchvalue, start) return the position of the last occurrence of specified character(s) in a string. You can use the following string to test your solution: var letters = "abcdefghijklmnopqrstuvwxyzabcdefghijklm"; Write the code in a separate.js and separate.html file.
Given subsets A and B of a universal set with 10 elements {0, 1, 2, 3, 4, 5, 6, 7, 8,9}. Write a C++ or Java program that uses bit strings to find A È B, A Ç B, and A – B. Print tothe screen set A, set B ( be sure to print out the name of the sets), as well as the set operation results(be sure to print out the name of the operations).The program requires that elements of subsets A and B are from user input. You can make theassumption that user input numbers are within the domain of the set {0, 1, 2, ..., 9} and there isno improper input.Additional requirements and reminders:• The use of STL, templates, and operator overloading is not permitted in any form.• Remember: You must use a bit string when representing a set. You may not use an array ofBoolean variables.• The elements of subset A and subset B must from user input. You may not hardcode the twosubsets in your program.
Create a template specialization to test for string and pointers-to-char string s = plus("he", "llo"); const char* sl = "aaa"; const char* s2 = "bbb"; char* s3 = plus(sl, s2);
java: Run length coding is a method to represent a string in a more compact manner. Each character that occurs more than 2 times in a row is represented by the character and a number following it. Two examples are: "abba" → "abba""abcccbbbba" → "abc3b4a"Write a function that calculates how many characters the encoded string is shorter than the original.
