Auotmatic Type Conversion and use of Explicit Keyword

1. By Constructor Conversion :
        See this situation .

Output :
Constructor B called
Hi inside Function
--------------------------------------------------------------------------------
Preventing constructor conversion.
This Behaviour of automatic calling of constructor . can be stopped if constructor is explicit.
Explicit Constructor: Constructor with explicit keyword.It prevents compliler from performing implicit (Unexpected) type conversions.


After this   func (a); will not get compiled .

Output:Compliation Fails
auotTypeConversion.cpp: In function `int main()':
auotTypeConversion.cpp:18: error: conversion from `A' to non-scalar type `B' requested

2. Operator Conversion :

OUTPUT:
inside conversion operator B--> A
inside A constructor i=10
Function call
