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++...
A pointing device, or sometimes called a pointing tool, isa hardware input devicethat allows the user to move the mouse cursor in a computer program or GUI operating system. Using a pointing device, you can point at or manipulate any object or text on the screen. What is pointing device f...

The CPU "ignores" the register content when using a memory operand such as [rcx+rsi*imm], in this example if RCX is a valid pointer and RSI is 0(implying access of the first element in an array) an access violation with address 0 occurs instead of reading [RCX]'s content. The CPU...
