integer 9,static_cast you need to properly complement the bits with a double-precision integer d. The result is 9.0. and reinterpret_ The behavior of cast is different: intn=9;Doubled=reinterpret_cast This time, the results are different. After the calculation, D contains the useless value. This is because the reinterpret_cast is simply copying n bits to D, without making the necessary analysis. Summarize: There are four

days and months, these two issues are resolved. A number of time functions have been listed in the previous article, and now the cast and convert used in this article are described in detail: Let's take a look at their grammar: CAST (expression as data_type [(length)]) CONVERT (data_type [(length)], expression [, style]) which Expression: Any valid expression. Data_type: Target data type. This include

Statement by netmd: I am not original, from the Internet, and a collection of two posts. I personally think this is more complete. ---------------------------------------------------------------------- Q: What is C style conversion? What are static_cast, dynamic_cast, and reinterpret_cast? What is the difference? Why? A: The meaning of conversion is to change the expression of a variable by changing its type to another type. To convert a simple object to another object of type conversion

Q: What is C style conversion? What are static_cast, dynamic_cast, and reinterpret_cast? What is the difference? Why? A: The meaning of conversion is to change the expression of a variable by changing its type to another type. To convert a simple object to another object of type conversion, you will use the traditional type conversion operator. For example, to convert a pointer of a floating point of the doubole type to an integer type:Code:Int I;Double D; I = (INT) D;Or: I = int (d ); I
