- in c++ Write a function named “contains” that accepts a vector of Variableobject pointers and a search string. It will return the list of Variableobject pointers that contains that search string.Please note that the list can contain pointers to both Variable or VariableString objectsor any of its derived class objects. Build a list of pointers pointing to mixed objects of Variable and VariableString objectsand show your function returns the mix of both.in c++ Write a function named “getLowest” that accepts a vector of pointers to Student objects. It will go through the list and return pointers to the Student or GradStudent with the lowest student ID and GPA. Please note that the vector contains pointers to either Student or GradStudent objects. Please show that you have tested with a vector of pointers of mixed Student and GradStudent objects (in the same vector) For example, if these students and grad students are in the list Student(2000, "John Smith", 4.0) GradStudent(3000,"Nancy Brown", 3.5, 2021) ; Student(1000, "Bob Johnson", 3.0) ; GradStudent(4000, "Tim Jackson", 2.0, 2020)) ; It will return pointers to these two objects: Lowest ID: ID(1000) NAME(Bob Johnson) GPA(3.00) Lowest GPA: ID(4000) NAME(Tim Jackson) GPA(2.00) GRADUATION-YEAR(2020)c programming Write a function f which takes three pointers to int variables (a, b, c). Then it should:-Set the first variable to the sum of values of the variables (a + b + c).-Set the second variable to difference between maximum and minimum of values ( max(a,b,c) - min(a,b,c) )-Set the third variable to median of a, b, c.For example:if a = 5, b = 10, c = 2Then f(&a, &b, &c) should:Set a to 17 (that is the sum)Set b to 8 (that is max - min = 10 - 2)Set c to 5 (that is the median of 5, 10 and 2)
- In this part your will have questions about C++ functions with pointers. • Write a function that takes three integer pointer as parameters and calculates sum of all numbers. This function must return the result as a pointer. • Declare a structure about a book which has properties such as name and price etc. Then create a list of book with 5 books. After that define a function that takes this book-list as a pointer and print out list items. • Write a function that calculates total price of the book in the book list (note: take the book-list as a pointer again). Write all function prototypes and test all functions within a single main functions.The following questions are related, using C++ a. Write a function template that receives a vector and prints the element of the vector. The return type must be void. b. Write a function template that receives a vector and returns the smallest element in the vector. c. Write a main program in which you populate a vector of three students (a mix of Student and GradStudent objects), call the function template in problem 5(a) to print the vector. Then call the function in 5(b) and display the smallest object.In C++, If you had the double-pointer above and also had these variables: type x, * q; And had executed these statements: q = &x; p = &q; How would a function given p by value be able to change the contents of x?
- Write a function in C++ called maximumGap that finds the maximum difference between corresponding entries in two arrays (that have the same capacity). There are 3 parameters, the 2 arrays and their capacity. If the arrays store 9, 0, 3 and 4, 7, 6 the maximum gap is 7 (between the second elements of the two arrays).Rather than enhancing the Unsorted List ADTs by adding amember function IsThere, you decide to write a client functionto do the same task.1. Write the specifications for this function.2. Write the function definition.Write in C++ When you're processing data, it’s useful to break up a text string into pieces using a delimiter. Write a function split() that takes a string, splits it at every occurrence of a delimiter, and then populates an array of strings with the split pieces, up to the provided maximum number of pieces. Function specifications: Name: split() Parameters (Your function should accept these parameters IN THIS ORDER): input_string string: The text string containing data separated by a delimiter separator char: The delimiter marking the location where the string should be split up arr string array: The array that will be used to store the input text string's individual string pieces arr_size int: The number of elements that can be stored in the array Return Value: int: The number of pieces the input text string was split into Note: No input will have delimiters in the beginning or the end of the string. (Eg: ",apple, orange" OR "apple, orange,") No input will have multiple…
- Is that right?For functions that are flexibly bound, you need pointers or references.For C++, How would I call or use a function that is passed by pointer or a reference? How would I use these in this example below? I understand how passing by value works, but when it comes to passing by references and pointers, that is when I get confused. #include <iostream> using namespace std; // passing by reference in this function void pass_ref(int &ref); // passing by pointer in this function void pass_ptr(int* ptr);In c++ Please Write the InOrder() function, which receives a vector of integers as a parameter, and returns true if the numbers are sorted (in order from low to high) or false otherwise. The program outputs "In order" if the vector is sorted, or "Not in order" if the vector is not sorted. Ex: If the vector passed to the InOrder() function is [5, 6, 7, 8, 3], then the function returns false and the program outputs: Not in order Ex: If the vector passed to the InOrder() function is [5, 6, #include <iostream>#include <vector>using namespace std; bool InOrder(vector<int> nums) { /* Type your code here */} int main() { vector<int> nums1(5); nums1.at(0) = 5; nums1.at(1) = 6; nums1.at(2) = 7; nums1.at(3) = 8; nums1.at(4) = 3; if (InOrder(nums1)) { cout << "In order" << endl; } else { cout << "Not in order" << endl; } vector<int> nums2(5); nums2.at(0) = 5; nums2.at(1) = 6;…
