There are no classes in C, so it's impossible to to write dynamic_cast in that language. C structures don't have methods (as a result, they don't have virtual methods), so there is nothing "dynamic" in it. Share Follow answered Feb 12, 2010 at 16:19 a1ex07 37.2k1212 gold ba...

MyClass *c = static_cast<MyClass*>(data); ... } int main() { MyClass c; start_thread(&func, &c) // func(&c) will be called .join(); } 在这个例子中,你已经知道传入的是一个MyClass 对象,没有必要进行运行时检验。 如果将一个非MyClass 对象传入func中,会如何呢,看下面code, ...
Difference between unsigned and unsigned int in C (5 answers) Closed 4 years ago. I'm new to C++, so please take this lightly. I was using resharper to convert some code from c-style casts to c++ style casts. This code here: (unsigned int)(ch - start) <= (unsigned int)(end -...
The static_cast operator in C++ serves as the operator that converts a variable from one data type to another, with a particular focus on transforming it into a float data type. The compiler performs this conversion exclusively with the static_cast, paying constant attention to const types, si...
C-style casts also ignore access control when performing astatic_cast, which means that they have the ability to perform an operation that no other cast can. This is mostly a kludge, though, and in my mind is just another reason to avoid C-style casts....
#include <iostream> int main() { int num = 65; // ASCII code for 'A' char c = static_cast<char>(num); // convert int to char std::cout << c << std::endl; // output: A return 0; } In the above example, we use static_cast<char> to convert the integer 65 to its ...
