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 static_cast conversion are safe. ...
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...

Static_cast c++ operator is a unary operator that compels the conversion of one data type to another. It can do implicit & explicit type conversions routines. Read more!

(or implicit ones). In many cases, explicitly statingstatic_castisn't necessary, but it's important to note that theT(something)syntax is equivalent to(T)somethingand should be avoided (more on that later). AT(something, something_else)is safe, however, and guaranteed to call the ...
Due to the likely situation where a leading hyphen will be used in custom CMake flags the syntax is slightly different than for other flags. The equals sign and double quotes must be used when specifying --cmake-flags.statick src/my_pkg --cmake-flags="-DFIRST_FLAG=x,-DSECOND_FLAG=y...
