- What are the ways to understand implicit type conversion?
- Do you know several ways of implicit type conversion? In programming, type conversion is a common operation that converts one data type to another data type. Type conversion can be explicit, that is, the data type to be converted is specified through code, or it can be implicit, that is, the data type conversion is automatically performed based on the context. Implicit type conversion is a very common feature in some programming languages, which can automatically complete type conversion without explicitly specifying type conversion. Next, we will introduce several common implicit type conversion methods and give the corresponding
