Please rewrite this program without the unnecessary vector. 1) The program below declares the following vectors, vector<string> all_words;vector<int> all_word_counts;vector<vector<int>> all_line_numbers; One of the vectors is unnecessary. 2) Sort the 2 or 3 parallel vectors in ascending order of all_words vector. #include <cassert> #include <iostream> #include <fstream> #include <iomanip> #include <iostream> #include <string> #include <vector> using namespace std; const string empty_string = ""; vector<string> getWords(const string& text); int findWord(const vector<string>& words, const string& word); int main() { vector<string> all_words; vector<int> all_word_counts; vector<vector<int>> all_line_numbers; string input_file_name; cout << "Source file name?

Question 5 Write the code for the function printRoster, it should print out the contacts in a format similar to the example. You can use a range-based for-loop and auto to simplify the solution, if you wish. #include #include #include #include #include using namespace std; void printRoster(map>>& roster) { // Fill code here int main() { map>> roster; roster["ELCO"]["CS-30"]. emplace_back("Anthony Davis"); roster["ElCo"]"cS-30"j. emplace_back("Talen Horton-Tucker"); roster["ElCo"Ï"BUS-101"].emplace_back("LeBron James"); roster["SMC"]["CHEM-101"].emplace_back("Russell Westbrook"); printRoster(roster); return 0; Here is the sample output: ElCo BUS-101: LeBron James CS-30: Anthony Davis Talen Horton-Tucker SMC CHEM-101: Russell Westbrook
Select all code lines that creates a vector with content {10, 10, 10, 10). You are also given the C-type array, an_array with content (10, 10, 10, 10). std::vector a_vector (an_array, an_array + sizeof(an_array)/sizeof(int)); std::vector a_vector [10, 10, 10, 10); std::vector a_vector (10, 4); std::vector a_vector = {10, 10, 10, 10); Ostd::vector a_vector (4, 10);
In c++ i have this information Type of Ticket &. Cost Monday. Adult= £25 and Child = £15 Thursday. Adult = £40 and child = £20 I have made a vector to store this information Vectorticket ={“Monday”, “Thursday”}; Vectoradult = {25, 40}; Vectorchildren ={15, 20}; Thr format of the adult and children vectors is in the order such that the first elements in those vectors correspond with the first element in the ticket vector Now what am struggling with, is i want the program to calculate the total cost of the tickets in correspondant with The user’s inputs which will be the quantity of how many tickets the user bought respectively (adult and children) So something like Monday 1 2 So 1 will be quantity of adult ticket and 2 will quantity of children ticket and the total costs of both added together

Write a value-returning function that receives an array of structs of the type defined below and the length of the array as parameters. It should return as the value of the function the sum of the offspring amounts in the array. Note: you do not need a main function or to create an array. Assume the array already exists from main. #include <iostream>using namespace std; // struct declaration for Animal struct Animal { // a string for animal typestring animal_type;// a string for color string color;// an integer for number of offspring. int number_of_offspring;}; // Main function to declare a structure variable of type Animal. int main(){struct Animal A1;return 0;}
