My program is ruuning perfectly only problem is that i must transform it to program uses class, class student . Am very beginer in using classes, so far i do very easy programs using classes.
I developing a C++ Program to deal with huge data computation. I am using Pointers to hold the data during computation. Current program i developed without using CLASS.
I would like to ask that will the memory usage will be reduced and computational time will be shortened if I modified my program implementing the CLASS into it ?
Whether it is possible to add a new class to a program? For example: program a is my main program and I want to use program b to just add a new class to program a.
Ive been writing this code all day and these errors have been killing.
Instructions: Car Class: Write a class named Car that has the following: year. An int that holds the cars model year. make. A string object that holds the make of car. speed. An int that holds the cars current speed.
In addition, the class should have the following member functions.
Constructor. The constructor should accept the car's year and make as arguments and assign these values to a object's year and make member variables. The constructor should initialize the speed member variable to 0.
Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object's year, make, and speed member variables.
accelerate. the accelerate function should add 5 to the speed member variable each time it is called.
brake. The brake function should subtract 5 from the speed member variable each time it is called.
Demonstrate the class in a program that creates a Car object, and then calls accelerate function five times. After each call to the accelerate function, get the current speed of the car and display it. The, call the brake function five times. After each call to the brake function, get the current speed of the car and display it.

Write the definition of the class dayType that implements the day of the week in a program. The class dayType should store the day, such as Sunday for Sunday. The program should be able to perform the following operations on an object of type dayType:
a. Set the day b. Print the day c. Return the day d. Return the next day e. Return the previous day f. Calculate and return the day by adding certain days to the current day. For example, if the current day is Monday and we add 4 days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday. g. Add the appropriate constructors
Write the definitions of the functions to implement the operations for the class dayType.
Line 23 error: prototype for 'void dayType::setDay(int)' does not match any in class 'dayType' Line 11 error: candidate is: void dayType::setDay() Line 36 error: prototype for 'void dayType::getDay(int) const' does not match any in class 'dayType' Line 13 error: candidate is: void dayType::getDay()
I know this is probably a really easy mistake but I am new to Programming and I have changed this code for days to no avail.
I am writing a program for a class where the user enters their age, how much money they have, and their full name. I know that I have to use the getline method to get the user's full name, and I know that I have to use cin.ignore() before that code, but i'm not sure why I have to use cin.ignore()?
I'm new to coding, and I have to write a program to display a class schedule to the user (the classes are entered into the program in strings like this:
in the format of an excel file (the user picks the classes they want to have) that then displays the course title and professor in the correct cell corresponding to the day/time the class meets. I've been googling it, and from what I've read, I think I need to use a csv file, but I don't know how to input the data into the file. I know the general format for how data is entered, but I don't know how to write it into a specific file or if I even have to (we covered txt files very briefly in my class, but never touched csv files).
I have the following problem on my C++ Program and I am not sure why it is not working. I am creating a infix to postfix program through an inherited class which I am not sure it is working.
#include <iostream> #include <stack> using namespace std;

An instructor needs you to write a program that will compute the final average grades in her class. There are 5 students in the class. Each student must take 2 exams and 4 quizzes as part of their final grade. The weight of each toward the final grade is as follows:
You must use arrays to store each students 3 digit ID number, exam scores and quiz scores. A multi-dimensional array is mandatory. Request from the user the information needed then output all of the information as well as the final average grade for each student.
I am currently learning OOP, and I can't figure out what the problem is with my header file. The rest of the program complies fine though. I am using g++ on UNIX.
myClass.h:9:23: error: Rectangle.h: No such file or directory myClass.h: In function ‘int main()’: myClass.h:13: error: ‘Rectangle’ was not declared in this scope myClass.h:13: error: expected `;' before ‘rect’ myClass.h:14: error: ‘rect’ was not declared in this scope
Code: myClass.h /* This header file contains, The main function for my rectangle class program.*/
#include "Rectangle.h" using namespace std; int main(){ Rectangle rect; rect.displayMaxRectangles(); rect.process(); rect.summary();
I'm supposed to build a banking simulation program around the BankAcct class, which provides the following service: create new account with unique account number (maximum 5 accounts created in a single test running); deposit/withdraw; print information of all existing account. I was running a test program with only 2 services first, namely creating new account and depositing, but the program just keep on crashing and I couldn't figure out why.

I am having a issues with an assignment in my class and don't really understand why. I am getting undeclared identifier errors even though I have declared and I am also getting an error. Here is the code:
Last time I came to you all with an error it was a simple brain fart on my part but I don't think this one is like that. I would love to tell you what the program is supposed to do but I still do not really know, which might be part of the problem. I guess it outputs different sized rectangles...
I am making a very basic parent/child class based program that shows polymorphism. It does not compile due to a few syntax errors reading "function call missing argument list. Lines 76 and 77, 81 and 82, and 86 and 87.
#include<iostream> using namespace std; class people { public: virtual void height(double h) = 0; virtual void weight(double w) = 0;
I've got this sorting program that uses variables from another class but I'm not sure why its not recognizing it. I'm getting an error length and list not declared in this scope.

I am having trouble of exactly how "class" works. I dont know what the difference between set and get is. I have this code:
#include <iostream> #include <cmath> using namespace std; class Point { private: double px; double py;

How to get void Triangle::setBottomLeftX(const double x) to work.
Implement the get and set member functions for the class Triangle. Use the appropriate class attributes of the class Triangle.
a. The location of the bottom left vertex is stored in the member attribute blPoint. b. The top left vertex can be computed from blPoint and the height. c. The bottom right vertex can be computed from blPoint and the length.
I am trying to transform seconds into HH:MM:SS. I thought it would be easy using the TimeSpan functions however my hours exceed 24 hours now and then therefor it is not viable for use.
private string getFormattedTimeFromSecond(double second) { TimeSpan t = TimeSpan.FromSeconds( second ); string answer = string.Format("{0:D2}h:{1:D2}m:{2:D2}s", t.Hours, t.Minutes, t.Seconds); }
This is what I have tried, however it does not like it much when hours exceed 24.
