Assume that pointer ptr is a pointer to a double, and has initial value of 0xfc0f. What is the value of ptr after the pointer has been decremented? (assume a 4 byte double) Group of answer choices 0xfb0e 0xfc13 0xfc0b 0xfc0e

Game of Chess in C++ The objective of this assignment is to practice concepts related to inheritance, overriding, polymorphism, and abstract classes, to program the basics of a chess playing program. About: Chess is played on an 8 X 8 board where the initial placement of pieces. The white king is on e1, and the black king is on e8. Each chess piece can move in a specific way. Follow a simplified version. Most importantly, ignore an important rule in chess: Moving any piece in a way that puts your own king in check is illegal. Since we don't know what check means, for us a move is legal if the piece we are moving has an empty square to move to or can capture (replace) an opponent's piece (including their king). The king does not move at all. Nor can it castle the queen and knight can't move either. A pawn in the initial position may move one or two squares vertically forward to an empty square but cannot leap over any piece. Subsequently it can move only one square vertically forward…
