constructor overloading in c 2b 2b

1Constructor overloading in Java is a technique of having more than
2one constructor with different parameter lists. 
3They are arranged in a way that each constructor performs a different task.
4They are differentiated by the compiler by the number
5of parameters in the list and their types.

8    int id;  
9    String name;  
10    int age;
11    
12    Student5(int i,String n){  
13    	id = i;  					//creating two arg constructor
14    	name = n;  
15    }
16    
17    Student5(int i,String n,int a){  
18    	id = i;  
19    	name = n;					//creating three arg constructor    
20    	age=a;  
21    }

23    void display(){System.out.println(id+" "+name+" "+age);}  
24    	public static void main(String args[]){  
25    	Student5 s1 = new Student5(111,"Karan");  
26    	Student5 s2 = new Student5(222,"Aryan",25);  
27    	s1.display();

1Yes, the constructors can be overloaded by
2changing the number of 
3arguments accepted by the constructor
4or by changing the data type of 
5the parameters

1class Point
2{
3public:
4	Point& operator++() { ... }		// prefix
5	Point operator++(int) { ... }	// postfix
6  	friend Point& operator++(Point &p);			// friend prefix
7  	friend Point operator++(Point &p, int);		// friend postfix
8  	// in Microsoft Docs written "friend Point& operator++(Point &p, int);"
9};
