Suppose you have the following C$++$ code

$[10$ Marks$]$Perfom Unary Increment overloading $()$ on object s such that the value of qyt on s is $11$ and display this value. Also perfom Logical not $(!)$Unary Operator Overloading on object s such that the value of qyt on s becomes $-11$ and display this value. Hint, have $2$ function for unary increment overloading $()$ and logical not overloading $(!)$ in the stock class and call these operator functions in the main program and display their results.The output should look like these:value after unary increment:qty: $11$value after logial not:qty: $-11$
