Sum of the series Using Constructor Overloading in C++

Sum of the series Using Constructor Overloading in C++.

The concept of using more than one constructor with the same name 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_Constructor_Overloading(int n) and another constructor as T4Tutorials_Constructor_Overloading(int num1,int num2).
All constructors with the same name and have the same number of parameters but of different data types.
- T4Tutorials_Constructor_Overloading(int n) and another constructor as T4Tutorials_Constructor_Overloading(double n).

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

T4Tutorials_Constructor_Overloading(int n) and another constructor as T4Tutorials_Constructor_Overloading(int num1,int num2).

#include<iostream>
using namespace std;
class T4Tutorials_Constructor_Overloading
{
	protected :
		int i,k;
		int n,sum;
		int num1, sum1;
		int num2, sum2;
	public :
		T4Tutorials_Constructor_Overloading(int n)
		{
			
			i=1;k=9,sum=0;
		for(int i=1;i<=n;i++)
				{
					sum=sum+k;
					k=k*10+9;
				}
                cout<<"sum of series"<<sum;
			}
		
		T4Tutorials_Constructor_Overloading(int num1,int num2)
		{
			i=1;k=9,sum1=0;
		for(int i=1;i<=num1;i++)
				{
					sum1=sum1+k;

Output

Please Enter 1 FOR Single parameter constructor.

Please Enter 2 FOR Multiple Paramter construcor.

You Have Selected Single Parameter constructor.

Please Enter a Number to find series :
