const_cast<type> (expr) − The const_cast operator is used to explicitly override const and/or volatile in a cast. The target type must be the same as the source type except for the alteration of its const or volatile attributes. This type of casting manipulates the const attribute of ...
This is called a downcast. The static_cast operator allows you to perform safe downcasts for non-polymorphic classes. Note that static_cast relies on static (compile-time) type information and does not perform any run-time type checking. This means that if acct does, in fact, not refer to...
Implicit conversions do not require any operator. They are automatically performed when a value is copied to a compatible type. For example: Here, the value of a has been promoted from short to int and we have not had to specify any type-casting operator. This is known as a standard conv...
Operator is used in situation where you are certain that the expression of casting is really an object of the appropriate type. Operator is used in situation where you are certain the the conversion is not going to fail. If conversion fail, it will just return, as if nothing went wrong. ...

Take control of the data in your applications, knowing when to apply the correct technique to change data types as needed. Learning objectives Use the casting operator to cast a value into a different data type. Use conversion methods to convert a value into a different data type. ...

On the other hand, the conversion in the opposite direction is known as explicit conversion. It needs a cast operator to convert higher data type into a smaller data type. This type of conversion is not type-safe and may result in loss of data. ...
