class class1 {
//variable declaration
};
class class2 {
public:
int func(void *msg);
// others func...
};
int class2::func(void *msg)
{
class1 *pointer = (class1 *)msg;
//others declaration.
}
I would like to ask reagrding on this line of code :
class1 *pointer = (class1 *)msg;
the class declaring a pointer to be equal with "(class1 *)msg"
My question is the parenthesis is for? as the msg is already declared as pointer based on the "int func(void *msg)" so is it the parenthesis is to avoid another declare of pointer in msg? as i know there is no such pointer declare or class pointer declare where by the astrik(*) is behind the variable eg: p*
hope you guys can explain to be the line of code..
thank you in advance.
