T/F 7. You can use, >, ==,!=, =, >= to match int, float, and double variables, but you must use compareTo(), equals(), and equalsIgnoreCase to compare char and String variables ().

C++ Code: Oj is a cruel but wise student of his class. Because of his bad habits, one day his math teacher got angry and challenged him to do a few maths. Yes, being a high school student solved all the questions from the math, matrics and maths topics but l could not solve a single question. The question asked to find the sum of all integers is from 1 to N so that 2i + 1 is divided by 3. You being Oj's friend don't want to make her feel ashamed and she volunteered to help. Input 1 2 Output 1

in c++   i have this struct    struct Student {     string firstName, lastName;     int pointTotal; }; void printStudent(const Student & s) {    cout << s.pointTotal << "\t" << s.lastName << ", " << s.firstName << endl;}void printAll(Student students[], int numStudents) {    for (int i = 0; i < numStudents; i++)        printStudent(students[i]);    cout << endl;}int main() {    const int NUMSTUDENTS = 7;    Student students[NUMSTUDENTS] = { {"Brian", "Jones", 45},{"Edith", "Piaf", 45},{"Jacques", "Brel", 64},{"Anna", "Brel", 64},      {"Carmen", "Jones", 45} , {"Carmen", "Brel", 64}, {"Antoine", "Piaf", 45}, {"Pascal", "Piaf", 64} };    printAll(students, NUMSTUDENTS);    sortByPointTotal(students, NUMSTUDENTS);    printAll(students, NUMSTUDENTS);    return 0;}   i need to make a function that uses bubble sort(coded from scratch), but modify it so that the comparison for out-of-order elements takes into account all three fields:…
