In explicit casting, the programmer needs to explicitly specify the conversion using casting operators or functions provided by the language.
Note: In languages like Python and JavaScript, which are dynamically typed, explicit type casting is achieved through conversion functions rather than traditional casting syntax.
C++
int num_int = 10;
float num_float = static_cast < float >(num_int);
|
C
float num_float = 10.5;
int num_int = ( int )num_float;
|
Java
double num_double = 10.5 ;
int num_int = ( int )num_double;
|
Python
num_float = 10.5
num_int = int (num_float)
|
C#
double num_double = 10.5;
int num_int = ( int )num_double;
|
Javascript
let num_float = 10.5;
let num_int = parseInt(num_float);

Implicit and Explicit type casting
In programming, type casting is a way to convert data from one type to another. Implicit type casting happens automatically, while explicit type casting requires manual intervention. This article explores the differences between implicit and explicit type casting, their uses, benefits, and considerations in programming.
