WebJul 30, 2024 · In C like cast sometimes we can cast some type pointer to point some other type data. Like one integer pointer can also point character type data, as they are quite similar, only difference is character has 1-byte, integer has 4-bytes. In C++ the static_cast<> () is more strict than C like casting. It only converts between compatible types. Example WebMay 30, 2024 · reinterpret_cast is a type of casting operator used in C++. It is used to convert a pointer of some data type into a pointer of another data type, even if the data types before and after conversion are different. It does not check if the pointer type and data pointed by the pointer is same or not. Syntax :

WebNov 30, 2024 · A static_cast c++ operator is a unary operator that compels the conversion of one data type to another. This is the most basic cast available. The static_cast takes a long time to compile, and it can do implicit type conversions (such as int to float or pointer to void*) as well as call explicit conversion routines (or implicit ones). WebJan 26, 2024 · The static_cast (4.0) takes that value stored as a double and returns an int object still containing the same value — the number four. The value didn’t change, only the representation of that value changed. Of course, this is not always possible. If we write static_cast (4.1), the value “number 4.1” cannot be stored in an int . kursus pertukangan kayu
