What is a foreign key and how it works?

Assume that you have an array of integers named a. which of these code segments print the same results? int i = 1; while(i < a. length) { system. out. println(a[i]); i++; } int i; for (i = 0; i < a. length; i++) { system. out. println(a[i]); } for (int i : a) { system. out. println(i); } i and ii only ii and iii only i and iii only all three print the same results. all three print different results.

Convert and simplify the following sentences to conjunctive normal form (cnf): (a) (p → (q → r)) → (p → (r → q)) (b) (p ∧ q) → (¬p ↔ q) (c) ((p → q) ∧ ¬q) → ¬p

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; }};
