Which is the correct statements from the below. a. If a class has dynamic members, we must exit whenever allocation failis to avoid referring to bad data later in the class methods. b. If a class has dynamic members, we must check successful allocation in every method that attempts to refer to the dynamic members' data. c. If a class has dynamic members, we must call the destructor manually as soon as we are done with the object. d. If a class has dynamic members, we must use the delete operator to dispose of any objects created of the class.
This assignment is about OOP: Given Human class (Human.java) , please write a Student class (Student.java). This Student class is one child class of Human.

For this assignment please use 2 arrays. Write a program DiscreteDistribution.java that will take an integer command-line argument m, followed by a sequence of positive integer command-line arguments a1,a2,…,ana1,a2,…,an, and will print m random indices (separated by whitespace), choosing each index i with probability proportional to ai.

Suppose we implement the += operator as shown in the following. What goes wrong with b += b ? void bag::operator +=(const bag& addend) // Library facilities used: cassert{ size_type i; // An array index assert(size( ) + addend.size( ) <= CAPACITY); for (i = 0; i < addend.used; ++i) { data[used] = addend.data[i]; ++used; }} Group of answer choices If we activate b += b, then the private member variable size is the same variable as addend.size. The size( ) + addend.size( ) is less than CAPACITY. So the program after the assert statement will be executed. If we activate b += b, then the private member variable size is the same variable as addend.size. The size( ) + addend.size( ) is larger than CAPACITY. So the program after the assert statement will not have chance to be executed. If we activate b += b, then the private member variable used is the same variable as addend.used. Each iteration of the loop adds 1 to used, and hence…
