- 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…arrow_forwardWRITE IN C++ A Date class is described by month(m), day(d), year(y). An Employee is described by a unique data structure having a name (e.g. “George”), salary(75000.25) and date_of_birth (06, 10, 1998). Calculate the number of days between his day of birth and (09, 20, 2023). Assume that the Employee object contains a Date sub-object)arrow_forwardA strongly-typed data type implementation supports strongly-typed data, whereas a loosely-typed data type implementation supports loosely-typed data.arrow_forward
