Q2. Explain about casting?
Ans. 
Casting is the process of converting one data type into another in programming.
• Casting is used to change the data type of a variable.

• It can be done implicitly or explicitly.

• Implicit casting is done automatically by the compiler.

• Explicit casting is done manually by the programmer.

• Casting can lead to data loss or unexpected results if not done carefully.

• Example: Casting an integer to a float, or a float to an integer.
