Suppose that the bag class is efficiently implemented with a fixed array with a capacity of 4000, as in Chapter 3 of the class text. We execute these statements: bag b; b.insert(5); b.insert(4); b.insert(6); b.erase_one(5); Group of answer choices b.used is 2, b.data[0] is 4, b.data[1] is 6 b.used is 2, b.data[0] is 6, b.data[1] is 4 b.used is 3, b.data[0] is 4, b.data[1] is 6 b.used is 3, b.data[0] is 6, b.data[1] is 4
IN JAVA intends to auto generate test cases for a function foo that has k integers as input arguments, i.e., foo(int n1, int n2, …, int nk). Each argument belongs to a different equivalence class, which are stored in a downloadable Eq.txt file. The content is shown below and may be modified to handle more inputs and equivalence classes. 1, 15; 16, 30 1, 10; 11, 20; 21, 30 1, 5; 6, 10; 11, 15 1, 3; 4, 6; 7, 9; 10, 12 1, 12; 13, 24 For this file, the nth row describes the nth input. Take the second row for example. There are five input arguments. The data 1, 10; 11, 20; 21, 30 indicates that argument n2 has three equivalence classes separated by the semi-colons. Develop an internal method “private int check(int val)” that returns the equivalence class the val is in. The result of check(val = 3) for n2 will be 1 and check(val = 25) for n2 will be 3. Regarding the function foo, it computes the sum of the returned values by the check function for all input arguments. Follow the contents…

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…
