Constructors, Destructors & Inheritance by https://padlet.com/suhailclassroom2020/3eh0xd1prt1ui0kv en-us 2020-07-14 06:47:00 UTC 2025-12-08 11:41:39 UTC hello@padlet.com https://padlet.net/icons/png/1f4da.png Constructor suhailclassroom2020 https://padlet.com/suhailclassroom2020/3eh0xd1prt1ui0kv/wish/653955250 A constructor is a special member function which has the same name as the class-name.

The main use of constructor is to allocate memory for the objects 

It is declared in the public part of the class.
It does not return any values

It can have arguments
Default constructor is called when an object is created

Constructor can be called implicitly or explicitly

Default constructor will be called automatically once the object is created.

By default, C++ compiler creates a default constructor by itself even if we don’t create to reserve memory for the class.

It is used to initialize instance variables.

Parameterized constructor can be called implicitly or explicitly

For example,
                              Integer I2(I1);
Would define the object I2 and at the same time initialize it to the values of I1. Another kind of statement is 
                              Integer I2 = I1;
The process of initializing through copy constructor is known as copy initialization.

•  The main use of destructor is to de-allocate memory for the objects 
•  It is declared in the public part of the class.
•  It does not return any values
•  It cannot have arguments
•  Destructor is called when a block ends or program ends.
