Constructor Overloading in C++
Using Constructor Overloading in C++?
Explanation
Constructors Overloading are used to increase the flexibility of a class by having more number of constructor for a single class. By have more than one way of initializing objects can be done using overloading constructors.
Result :
Overclass A's x,y value:: 0 , 0
Overclass A1's x,y value:: 4 ,4
Overclass A2's x,y value:; 8 , 12
In the above example the constructor "Overclass" is overloaded thrice with different intialized values.
Example :
| #include <iostream.h> class Overclass { public: int x; int y; Overclass() { x = y = 0; } Overclass(int a) { x = y = a; } Overclass(int a, int b) { x = a; y = b; } }; int main() { Overclass A; Overclass A1(4); Overclass A2(8, 12); cout << "Overclass A's x,y value:: " << A.x << " , "<< A.y << "\n"; cout << "Overclass A1's x,y value:: "<< A1.x << " ,"<< A1.y << "\n"; cout << "Overclass A2's x,y value:; "<< A2.x << " , "<< A2.y << "\n"; return 0; } |
Result :
Overclass A's x,y value:: 0 , 0
Overclass A1's x,y value:: 4 ,4
Overclass A2's x,y value:; 8 , 12
In the above example the constructor "Overclass" is overloaded thrice with different intialized values.
