- Explore potential risks posed by implicit type conversions
- Why is implicit type conversion considered a potential risk in programming? Conceptually, type conversion refers to the process of converting a value of one data type into another data type. In most programming languages, type conversion can be done explicitly or implicitly. Explicit type conversion is a conversion that is explicitly specified by the programmer and performed explicitly in the code. Implicit type conversion is performed automatically, and the compiler automatically converts one type to another type according to rules. Although implicit type conversions make code more concise and convenient in some cases
