R(a, b) currently contains the four tuples (0,4), (1,5), (2,4), and (3,5). s(c, d) currently contains the four tuples (2,10), (3,11), (4,12), and (5,13). as a result, certain insertions and deletions on s are illegal, as are certain updates or insertions on r. you should develop simple tests for illegal operations of these four kinds. then, show your understanding by indicating which of the following modifications will not be rejected because of a constraint violation.

a) inserting (5,0) into r.
b) inserting (1,4) into r.
c) updating (2,4) in r to be (2,2).
d) updating (3,5) in r to be (3,1).

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; }};
