When using semaphores, a process invokes the \texttt{wait()}wait() operation before accessing its critical section, followed by the \texttt{signal()}signal() operation upon completion of its critical section. Consider reversing the order of these two operations—first calling \texttt{signal()}signal(), then calling \texttt{wait()}wait(). What would be a possible outcome of this?

Idon understand these and need some ! ?

Write a full class definition for a class named player , and containing the following members: a data member name of type string .a data member score of type int .a member function called setname that accepts a parameter and assigns it to name . the function returns no value.a member function called setscore that accepts a parameter and assigns it to score . the function returns no value.a member function called getname that accepts no parameters and returns the value of name .a member function called getscore that accepts no parameters and returns the value of score .this is what i have, aparently this is wrong: class player{private: string name; int score; public: void player: : setname (string n){name =n; }void player: : setscore (int s){score = s; }string player: : getname (){return name; }int player: : getscore (){return score; }};
