Q# Describe what a data structure is for a char**? (e.g. char** argv) Group of answer choices A. It is a pointer to a single c-string. B. It is an array of c-strings C. It is the syntax for dereferencing a c-string and returning the value.

In C++ struct myGrades { string class; char grade; }; Declare myGrades as an array that can hold 5 sets of data and then set a class string in each position as follows: "Math" "Computers" "Science" "English" "History" and give each class a letter grade

Declare a student structure that contains : Student's first and last nameStudent IDCreate the following functions: getStudentInfo(void) Declares a single student, uses printf()/scanf() to get inputReturns the single student backprintStudentInfo(student_t *st_ptr) Takes the pointer to a student (to avoid making a copy)Prints out all of the student informationDeclare an array of five studentsUsing a for loop and getStudentInfo() function, get input of all the studentsUsing a for loop and printStudentInfo() function, print all the output of all students.

C++ Data Structure:Create an AVL Tree C++ class that works similarly to std::map, but does NOT use std::map. In the PRIVATE section, any members or methods may be modified in any way. Standard pointers or unique pointers may be used.** MUST use given Template below: #ifndef avltree_h#define avltree_h #include <memory> template <typename Key, typename Value=Key> class AVL_Tree { public: classNode { private: Key k; Value v; int bf; //balace factor std::unique_ptr<Node> left_, right_; Node(const Key& key) : k(key), bf(0) {} Node(const Key& key, const Value& value) : k(key), v(value), bf(0) {} public: Node *left() { return left_.get(); } Node *right() { return right_.get(); } const Key& key() const { return k; } const Value& value() const { return v; } const int balance_factor() const {...
