C++ Sample: Class Method Overloading

Sometimes the only thing that restricts you from creating an A+ paper is the absence of a suitable sample, but don’t worry – we are here to solve this problem. We gladly present to you a C ++ sample created by our experts to serve as an example of how such assignments should be done. We wish to remind you that you are not allowed to use the text and parts of code provided here in any ways that violate the copyright laws. Moreover, there’s a better way of dealing with your academic problems – place an order to get your personal programming sample done according to your requirements.

Fill in the order form, choose an expert and wait for the assignment to be done for you. You can also chat with your expert during the writing process in case the initial requirements have changed or you have some additional questions. Once your personal C ++ sample is ready, you can check whether it corresponds to your requirements and request any amendments if needed – only after that you will be asked to pay. Check the sample below and place your order if you want a sample of similar quality written specially for you according to your demands and instructions.

Class methods can be overloaded as well as the usual functions. This is especially handy if you need to make a few constructors that will take different parameters.

For example, let’s try to create a foundation class decimal which implements long arithmetic for numbers of arbitrary precision. In such cases, the number is typically stored within a row, and mathematical operations logic is implemented by writing corresponding operators.

Let’s make a class constructor which can take both the line and the number of the type double as parameters.

// string
decimal num1("10000000.999999");
// number
decimal num2(10000.0);

In order to support the universality, we will do two different constructors for strings and numbers:

class decimal
{
public:
	// string constructor
	decimal(string number)
	{
		clog << "First constructor called\n";
	}

	// double constructor
	decimal(double number)
	{
		clog << "Second constructor called\n";
	}

private:
	string number;
};

If we will use the line it will call the first constructor, if we input the number it will use the second one.

The full text of the program:

#include <iostream>
#include <string>

using namespace std;


class decimal
{
public:

	decimal(string number)
	{
		clog << "First constructor called\n"; this->number = number;
	}


	decimal(double number)
	{

		clog << "Second constructor called\n";
	}

private:
	string number;
};

int main()
{

	decimal num1("10000000.999999");

	decimal num2(10000.0);
	cin.get();
	return 0;
}

The result of the program:
