When to use type casting in type conversion?


Asked by Raya Mayer on Dec 13, 2021 FAQ



Explicit type conversion requires a type casting operator. Keep in mind the following rules for programming practice when dealing with different data type to prevent from data loss : Integers types should be converted to float. Float types should be converted to double.
Likewise,
This process is also called type casting and it is user defined. Here the user can type cast the result to make it of a particular data type. Type indicated the data type to which the final result is converted. This is done to take advantage of certain features of type hierarchies or type representations.
In respect to this, Convert a value from one data type to another data type is known as type casting. There are two types of type casting: Converting a lower data type into a higher one is called widening type casting. It is also known as implicit conversion or casting down.
Next,
Typecasting is converting one data type into another one. It is also called as data conversion or type conversion. It is one of the important concepts introduced in 'C' programming. 'C' programming provides two types of type casting operations: Implicit type casting means conversion of data types without losing its original meaning.
Consequently,
In typing casting, the destination data type may be smaller than the source data type when converting the data type to another data type, that’s why it is also called narrowing conversion. destination_datatype = (target_datatype)variable; (): is a casting operator.
