class Car { public: int speed; }; int main() { int Car::*pSpeed = &Car::speed; return 0; } Why does C++ have this pointer to a non-static data member of a class? What is the use of this strange pointer in real code?c++...
Otherwise if the value you want to return is too big to fit into a LRESULT, a convention is to return a pointer to the value you are trying to communicate to the caller. In your example, you wanted to return a Rect. Chances are sizeof(Rect) > sizeof(LRESULT), so you would need ...

However, if you debug with a break in the expression std::cout << p << '\n'; you'll verify that the character string obtained by the compiler is given by the bytes 61 62 3F 3F 00, which is clearly a bug.But what is exactly the problem here? Is it that the compiler doesn't...
Since this is not part of the integer, it will remain in the input buffer until a new extraction occurs. The problem with getline() is that is doesn't ignore preceding whitespace in the buffer, like most operations do. When trying to read a string, it will first encounter the newline ...

Now in course.cpp implement the Course constructor. 1234 Course::Course(std::string& variableName) { //your code here } To figure out what is done in this function, look at what parameters the function accepts and what variables were originally in the struct given to us that the ...
