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

Three different looping examples in C++

Design a While Loop that lets the user enter a number. The number should be multiplied by 10, and the result stored in a variable named product. The loop should iterate as long as product contains a value less than 100. Design a For loop that calculates the total of the following series of numbers: 1/30+2/29+3/28+...30/1

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

Examples of C++ Programs

An easy to understand example of arithmetic in C++

Write a c++ program. 1. As a part time student and a part time worker, you earn $4.50 an hour. Your parents will buy you a used car, but you must pay for the gas. gas costs $1.10/gallon and you use 20 gallons/week. How many hours will you work each week to pay for the gas to fuel your car?

Reading and writing a file with a Java Program

Please assist with the following: Write a C++ or Java program that reads from one file and writes to another, in both Windows and Linux operating systems. Keep in mind that the key goal in this assignment is to identify the command used to copy a file. The other goal is to determine how to perform system calls in each operati

Please include the code and the .exe file. For the Graph in figure 16-28(a), replicate the trace of Dijkstra's algorithm to find the minimum path from vertex A to F. For each step, create the list of minInfo elements in the priority queue and indicate which element is removed from the queue. Please see Graph 16-28(a) below

C++ using multidimensional dimensional array

A certain professor has a file containing a table of student grades, where the first line of the file contains the number of students and the number of scores in the table; each row of the table represents the exam scores of a given student and each column represents the scores on a given exam. The maximum possible score on eac

C - Write a Function that Accepts a Score for a Driver's License

(Please include comments in the code). It is required that in all assignments a Cast should be used to convert float to int. 1- Write a function that accepts a score for a driver's license facility, an int or a float, and returns a letter. If the score passed in is less than 75, then the letter returned is an F for Fail. Ot

Data Structures - C++

Implement, according to the instructions in parts (a) and (b), the fnction count(), which takes item as argument and returns the number of times item occurs in a list. template <typename T> -------please see attachment for this portion int count (const list<T>& aList, constT& item); a) implemen

output of the codes

Trace the following code and give the output: (be sure to include the code used) int arr[] = {4, -6, 22, 7, 13, 8}; in arrSize = sizeof(arr)/sizeof(int); vector<int>v(arr.arr+arrSize); while (!v.empty()) { cout <<v.back() <<" "; v.pop_back(); }

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();

Westfield Carpet Company

Use C++ to write a program: The Westfield Carpet Company has asked you to write an application that calculates the price of carpeting for rectangular rooms. To calculate the price, you multiply the area of the floor(width times length) by the price per square foot of carpet. For example, the area of floor that is 12 feet long

Data Structures C++ for array generation
