What is typecasting?

The typecasting is a process of converting one data type into another is known as typecasting. If we want to store the floating type value to an int type, then we will convert the data type into another data type explicitly.

Syntax

(type_name) expression;

In C, typecasting refers to the explicit conversion of a variable from one data type to another. It involves specifying the desired data type in parentheses before the variable whose type you want to change. Typecasting can be useful in situations where you need to perform operations that involve different data types, such as assigning a floating-point value to an integer variable or vice versa.

For example:

c
float x = 3.14;
int y;

y = (int)x; // Typecasting float x to an integer before assigning it to y

In this example, (int)x typecasts the float variable x to an integer before assigning it to the integer variable y. Without typecasting, the compiler may issue a warning or error because of the potential loss of data (in this case, the fractional part of the floating-point number is truncated).

It’s important to note that typecasting can lead to loss of precision or unexpected results if not used carefully.
