What reasons make the use of C-style casting undesirable in modern C++ projects?

Using C-style casts (e.g., (int)variable or (MyClass*)ptr) in modern C++ projects is discouraged for several reasons:

• Lack of explicit semantics: C-style casts do not indicate which specific cast is performed (static_cast, reinterpret_cast, const_cast), making the code harder to understand.

• Safety: C-style casts can perform multiple types of casts simultaneously, including unsafe reinterpret_casts, increasing the risk of errors and undefined behavior.

• Lack of compiler control: C++ casts are more strictly checked by the compiler, helping to catch errors at compile time.

• Readability and maintainability: Explicit C++ casts make the programmer's intentions clear to other developers.

Example of correct usage:

int i = 10;
double d = static_cast<double>(i); // Explicit and safe cast

Therefore, it is recommended to use C++ casts (static_cast, dynamic_cast, const_cast, reinterpret_cast) instead of C-style casts to improve safety and code readability.
