Constructor Overloading C++, Sum of n number of odd natural numbers

By Prof. Fazal Rehman Shamil April 21, 2020 C++ 0 Comments

Let’s see the C++ program to show the Sum of n number of odd natural numbers by using the Constructor Overloading.

We are using more than one constructor of the class T4Tutorials_Sum_Constructor_Overloading with the same name, and it is called constructor overloading.

In this program, the constructor must obey one or both of the following rules.

All constructors with the same name and having a different number of parameters.
- T4Tutorials_Sum_Constructor_Overloading (int a) and another constructor as T4Tutorials_Sum_Constructor_Overloading(int two, int three).
All constructors with the same name and have the same number of parameters but of different data types.
- T4Tutorials_Sum_Constructor_Overloading (int a) and another constructor as T4Tutorials_Sum_Constructor_Overloading (double a).

Note: In this example, we are overloading the constructor with the following rule;

T4Tutorials_Sum_Constructor_Overloading(int a) and another constructor as T4Tutorials_Sum_Constructor_Overloading(int two,int three).

#include<iostream>
using namespace std;
class T4Tutorials_Sum_Constructor_Overloading
{
	private :
		int i,n,number1 ,number2;
	public	:
		T4Tutorials_Sum_Constructor_Overloading(int a)
		{
			n=a;
			int sum=0;
			for(int i=1;i<=n;i++)
			{
				cout<<"The output is:"<<endl;
				cout<<2*i-1<<" ";
				sum=sum+(2*i-1);
				cout<<endl;
			}
			cout<<"The sum of the given input  = "<<sum<<endl;
		}
		
		T4Tutorials_Sum_Constructor_Overloading(int two,int  three)
		{
			cout<<"For 1st Input Answer is Given below"<<endl;
			number1 =two;
			int sum1=0;
			for(int i=1;i<=number1 ;i++)
			{
				cout<<"The output  is:";
				cout<<2*i-1<<" ";
				sum1=sum1+(2*i-1);
				cout<<endl;
			}
			cout<<"The sum of the given input  = "<<sum1<<endl;

			int sum2=0;
			for(int i=1;i<=number2;i++)
			{
				cout<<"The output   is:";
				cout<<2*i-1<<" ";
				sum2=sum2+(2*i-1);
				cout<<endl;
			}
