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).
T4Tutorials_Constructor() and another constructor as T4Tutorials_Constructor(int n1, int n2,int T4Tutorials_Difference).
