What are the methods of type casting in the C language?

In the C language, there are several methods for type casting.

1. Type casting operator: You can use the type casting operator to convert an expression to a specified type. Its syntax is: (type) expression. For example, you can use the type casting operator to convert an integer to a float: (float) num.
2. Library functions: The C standard library offers certain functions for performing specific type conversions. For example, you can use the atoi() function to convert a string to an integer, and the atof() function to convert a string to a floating-point number.
3. Bit manipulation: Strong type conversion can be achieved through bit manipulation. For example, it is possible to convert an integer to a character type using bit manipulation.

It is important to note that type casting may lead to data precision loss or overflow, so caution should be taken when performing type casting to ensure it is safe and reasonable.
