C/C++ :: Design / Implement And Test A Class That Represents Time In Minutes And Seconds
Nov 29, 2014
Design, implement, and test a class that represents an amount of time in minutes and seconds. The class should provide a constructor that sets the time to a specified number of minutes and seconds. The default constructor should create an object for a time of zero minutes and zero seconds. The class should provide observers that return the minutes and the seconds separately, and an observer that returns the total time in seconds (minutes x 60 + seconds). Boolean comparison observers should be provided that test whether two times are equal, one time is greater than the other, or one time is less than the other. (You may use RelationType and function ComparedTo if you choose). A function should be provided that adds one time to another, and another function that subtracts one time from another. The class should not allow negative times (subtraction of more time than is currently stored should result in a time of 0:00). This class should be immutable.
this is one of my main errors: Error1error C2653: 'Time' : is not a class or namespace namec:userskdesktop

I am looking for a function or any example that shows elapsed time in seconds and minutes. I didn't find any solution for both OS Win and Linux. I am looking for example that works for both - win and linux.

I want to convert seconds into hours, min and seconds. I was able to test it with a small equation turning seconds into hours but now it returns zeros for every entry.
Code:
#include <stdio.h>
void secCount(int *seconds, int *hours, int *min, int *sec);
int main(int argc, const char * argv[]) {
int sec=0, hours=0, min=0, seconds =0;

I have a Class called 'DataManager' which contains a list of my 'DataItem' objects (this are created by an XML file).
I have also created some custom controls which, among other things, has a property to link it to a "DataItem" object.
My question is, is it possible to create an instance of my DataManager class at design time (which runs all the code as it would at run time to create all the DataItems from the XML)?
I want to do this so that I can update my DataItem property in my custom controls to use a UITypeEditor which then allows me to link to a DataItem at design time.

I have a code to check the last time modification of a file using "gmtime". Is it possible to remove the seconds in the result?
Here is my code:
struct tm* clock;// create a time structure
struct stat attrib;// create a file attribute structure
stat("test.txt", &attrib);// get the attributes of afile.txt
clock = gmtime(&(attrib.st_mtime));// Get the last modified time and put it into the time structure

I need to get the current time, have the system sleep for a period of time, then return the difference in seconds.
#include <iostream>
#include <string>
#include <ctime>
#include <time.h>
#define _CRT_SECURE_NO_WARNINGS
using namespace::std;
// in the <ctime> library is a function time(0)
[Code] ....
I'm not receiving an errors but the return value is not correct. It's returning 1.4259 no matter how long it sleeps for.

i create a structure called time. Its three members, all type int called hours, minutes, and seconds. This is in 12:59:59 format and i finally want to print out the total number of seconds represented by this time value.
long totalsecs = t1.hours*3600 + t1.minutes*60 + t1.seconds
i am using this formula but facing errors?

I am trying to design and implement a program that consists of two classes. The Base class A is purely for supporting class B. I do not want to be able to create an object of class A. When object B is created it inherits from class A.
What is the best way to achieve this?

I have to write a program for class in which users will be inputting:
start time = startTime
number of minutes = callDuration
so first off, teacher wants us to input time as a floating point number such as 09.00
How do I validate the time so that users cant input i.e. 09.61 for every hour? In other words, so the user cant input minutes 60-99 for every hour.
then, when calculating:
endTime = startTime + callDuration
how would I make endTime display a correct time in such a situation: endTime = 09.45 + 00.30
so that it displays 10.15 not 09.75

Create a class to store a value that represents number of hours worked and number of days worked. Must ensure that the two representations are always consistent. I have to create 2 files, I'm pretty sure: a .cpp and a .h
This is what I have so far for my .h file (I know it's NOT functional...yet):
#include <iostream>
using namespace std;
class NumDays {
private:
double hours;
double days;
[Code] ...
I don't know how to start / create this .cpp file to define the variables.

when we would use add items at design time and when we would add them at run time
does it have anything to do with the page load method? if so, can i type this in source code instead?

I want to write a command line parsing library that is very flexible in terms of parsing style but I'm not able to design a mechanism that satisfies this requirements.
Generally i want to have a class that contains all the necessary information about how the command line has to be parsed.
Code:
// draft
class style {
public:
enum class type { // the basic style type
[Code] ....
Need completing the draft shown above, because for every basic style type there is an own set of extensions that applies only to this one specific style type.
Code:
// how a style object should be created
style parsing_style(style::type::posix, style::extension::gnu|style::extension::subcommand);
How to design the class. (using c++11 features like std::enable_if is fine)

smart pointer class is the one that take in charge of release allocated resource when itself destroyed.
recently,i want design a smart pointer class, it take in charge of release resource allocated by new or new[].
my problem how to design destructor, you should determine the pointer ptr is pointer an array or a single object.
the structure of this smart point class may be:
template<class T>;
class smart_pointer{
public:
smart_pointer(T* p):ptr(p){};
~smart_pointer(){

In the following code example of the State Design Pattern, in the main code at the bottom it defines an instance of class Machine, and then calls Machine::off;. Why doesn't it instead call fsm.off;?
Machine fsm;
Machine::off;
Then I tried imitating that by adding a class Abba, and then doing:
Abba a;
Abba::DoStuff();
but that didn't work. Why?
Full code example:
// StatePattern.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
using namespace std;
class Machine {
class State *current;

Assignment: Design a class to store measurements. The class should have two data items, feet and inches, both integers. The class must make sure that the number of inches never gets below zero or above 11. If inches is outside that range, adjust feet accordingly. (Yes this means feet might be a negative number.)
Create a default constructor and one which receives one integer, a number of inches.
Overload the following operators: addition, subtraction, equality, inequality, incrementation (both pre and post) (should add one to inches), and output (in the form of: F’I”)
Code:
#include <iostream>
using namespace std;
class measurements {
private:
int inches;
double feet;
[Code] ....

I need to create a GlobalConfig class. But I want to derive from it in another class.
Here's an example:
public class BaseConfig {
public string GlobalPath {get; set;}
}
public class ConfigA : BaseConfig {
public string pathA {get; set;}
}
public class ConfigB : ConfigA {
public string pathB {get; set;}
}
The idea behind is that I don't want to write the code multiple times and what's more important in class ConfigA I want to set GlobalPath and have access to it in ConfigB.
In other word I want class ConfigB to have a property GlobalPath which was set in class ConfigA.
To clarify I want to have only one object of Config in memory.
When I set BaseConf.GlobalPath to 'A', I want to access it from ConfigB.GlobalPath and also get 'A'.
I always design GlobalConfig as a static class, but static classes can't be inherited. So I tried to implement Singleton Pattern, but ConfigA can't find constructor of class BaseConfig because it's private.

I have been thinking about this all day and I am yet to come up with a good solution. So, I need to design an image class which should work with various data types (int, float, double etc.) and can also be multidimensional (2, 3, 4, 5). So, what I did was generate a template image class as follows:
Code:
template<typename T, int dimensions=3>
class Image {
private:
T * data;
};
Anyway, now I have various image formats that I want to support, so the easy thing to do is create a Factory sort of object which will call eventually generate the correct image.
So I want to create various image classes called ImageType1, ImageType2 etc. which will take the input image and generate the correct Image object. However, I do not want these objects to be templated because they need to be passed from functions and be used in a generic way.
So, at run time I will need to be able to do this…
Code:
class ImageType {
public:
ImageType() {
PolymorphicImage * image = new Image<float, 3>();
}
private:
PolymorphicImage * image;
};
So, I want my ImageType classes to contain the Image object and be able to generate it with the right template arguments at run time. Is there any way to do this without having multiple specialised definitions for ImageType?

I am struggling with how to efficiently design my class objects to support the outlining of a collection of items. The collection would be sorted but would also have the ability to indent and outdent individual items representing a Parent and Child relationship (see attached).
An item could indent up to 5 levels deep. A summary level would be considered a Parent while items below the summary level would be consider as children.

I'm playing with the idea of a singleton base class, but I'm having an issue with how to implement the GetInstance() function in the base class. Since I'm trying to make this ridiculously simple for the child, I'd like to handle that in the base.
class Singleton {
private:
static Singleton* instance;
Singleton() { Construct(); } // Private to avoid other instances
[Code] .....
It would be easy to use like so:
class Hello : public Singleton {
private:
std::string hello;
void Construct() { hello = "hello"; }
public:
std::string GetHello() const { return hello; }
};
Then the instance would be handled like so:
std::cout << Hello::GetInstance()->GetHello();

I am supposed to implement the member functions of class Person.
class Person {
public:
Person();
Person(string pname, int page);
void get_name() const;
void get_age() const;
[Code] ....
The code I wrote is below. Where I am struggling is the program does not allow me to input age. Therefore, I cannot test if my temp for age works. It automatically defaults to 0 because it hasn't taken input. Here is my code:
// Program Title: Person function
// Program Description: The program prompts the user for first and last name and age.
// It then prints the output that was provided by the user.
#include<iostream>
#include<string>
using namespace std;
class Person {

Well, basically, what I've been doing was creating a class that would implement the concept of Double Linked List, but that would behave like a queue ( the STL implementation is deque, or Double Ended Queue ).
The problem occured when I have been trying to generalize the class using templates. I mean, why use only integers ? Why not double or char or what not ?
Worked perfectly before including all the template stuff..
// Source.cpp <=> Main.cpp
#include <iostream>
#include "DList.h"
using namespace std;
int main(void) {
DList<int> *list;
list = new DList<int>();
[Code] .....
The errors returned by the compiler:

1 create a struct called complex which reprensts a complex number . both the real and imaginary compoents should be represented as doubles . ( 1 marks) .
2 write down a function called magnitude which has one parameter ( a struc complex) and a return type of double . it should return the maginude of the given parameter . ( 3marks) .
3 write a function called find_largest which has two parameter (one of type struct complex const * and the other type int) and a return type of struc complex . the two parameter represent an array of complex numbers and number of elements in that array . the function should return elements from array which has largest magnitude . this fucntion must called the magnitude function . ( 5 marks)
4 write a main function . your main fucntion . Your main fucntion should repeately prompt the user for complex number , storing them in an array. you should continuing reading in complex number until the user enters in both componets , at this point you should stop . you should not make an assumptions how many complex number the user will enter , ( i.e use realloc) after reading in complex numbers from the user you should print out real and imaginary components of the complex number with the largest magnitude.
Code:
#include<stdio.h>
struct complex {
double real;
double imag;
