static_cast can be used to convert from an int to a char. However, the resulting char may not have enough bits to hold the entire int value. Again, it is left to the programmer to ensure that the results of a s
px=static_cast<int *>(&y);//syntax error, can not convert double * to int * //可以这样理解,static_cast一般用于不同类型的数据的转换,而不能用于转换指针。而reinterpret_cast正好相反,其只能负责不同类型的指针转换。 reinterpret_cast运算符 个人认为,reinterpret_cast主要用于不同类型的指针的转换。 in...
The static_cast operator is used to convert variables to different data types, including float types, in C++. It can also be used for conversions involving pointers. Each C++ method, operator, and variable can have proper syntax and formats for creating the applications. #include <iostream> usi...
Syntax static_cast<target-type >(expression ) Returns a value of typetarget-type. Explanation Only the following conversions can be done withstatic_cast, except when such conversions wouldcast away constness(or volatility). 1)Ifexpressionis an lvalue of type “cv1Base” andtarget-...
To perform a static cast, we start with thestatic_castkeyword, and then place the type to convert to inside angled brackets. Then inside parenthesis, we place the expression whose value will be converted. Note how much the syntax looks like a function call to a function namedstatic_cast<typ...

We noted that both the enforcement of static semantic rules and the generation of intermediate code can be cast in terms of annotation, or decoration, of a parse tree or syntax tree. We then presented attribute grammars as a formal framework for this decoration process. An attribute grammar ...
