Type Casting

In C++, type casting refers to converting one data type to another. This can be necessary when performing operations involving different data types or when you need to ensure data fits into a specific type.

Mathematical operations and data types

When performing mathematical operations, the result’s data type is determined by the types of the operands. The rule is simple: the result’s data type is the larger of the two operands’ types. Here’s an overview of how it works:

• Adding a float and a double: The result will be a double.

• Dividing two integers: The result will be an integer.

• Multiplying an int and a double: The result will be a double.

The compiler automatically handles these conversions, ensuring that the result is stored in the appropriate type.

Implicit type casting

Implicit casting happens automatically when you assign the value of a smaller data type variable to a larger data type variable. This process ensures no data loss. Let's have a look at the following example:
