Write a c++ program to find out the sum of an A.P. series by using the constructor overloading.
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()and another constructor asT4Tutorials_Constructor(int n1, int n2,int T4Tutorials_Difference).
- All constructors with the same name and have the same number of parameters but of different data types.
T4Tutorials_Constructor(int n1, int n2,int T4Tutorials_Difference)and another constructor as4Tutorials_Constructor(double n1, double n2, double T4Tutorials_Difference).
Note: In this example, we are overloading the constructor with the following rule;
One constructor as T4Tutorials_Constructor() and another constructor as T4Tutorials_Constructor(int n1, int n2,int T4Tutorials_Difference).
