A Vector Class in C++

Your class VectorDouble will have a private member variable for a dynamic array of doubles. It will also have two member variables of type int; one called maxCount for the size of the dynamic array of doubles, and one called count for the number of array positions currently holding values. (maxCount is the same as the capacity o

C++ Recursion

A. What is direct recursion? b. What is tail recursion? c. Suppose hat intArray is an array of integers, and length specifies the number of elements in intArray. Also suppose that low and high are two integers such that 0 <= low < length. 0 <= high < length, and low < high. That is, low and high are two indices in intArray

C++ exception classes

Suppose an exception, class myException, is defined as follows: class myException { public: myException() { message = "myException thrown!"; cout << "Immediate attention required!" << endl; } myException (string msg) { message = msg; cout << "Attention required!" << endl; } string what() { retur

Data structures + C++

Please include the code. Trace the following code, and display the resulting elements in the list. int arr[] = {1, 2, 3, 4]; int arrSize = sizeof(arr)/sieof(int); list<int> intList (arr, arr+arrSize); list<int> :: iterator iter = intList.begin); int i; for (i=1; i <= arrSize; i++) intList.insert(iter++, i);

Data Structures + C++ STL

Give the value of v.size() after executing each of the following statements: (Be sure to include the code used to execute the statements. One program will be fine to execute all statements, no need to write multiple programs.) vector<int> v(25); v.push_back(-4); v.resize(40); m = v.back(); v.pop_back();
