Consider the following code: int diff = 0;
if (Math. abs(num1 - num2) == (num1 - num2))
{
diff = num1 - num2;
}
else if (Math. abs(num2 - num1) == (num2 - num1))
{
diff = num2 - num1;
}
Which of the following will have the exact same result?

I.

int diff = Math. abs(num1) - num2;
II.

int diff = Math. abs(num1 - num2);
III.

int diff = Math. abs(num2 - num1);
II and III only
I only
I sets diff to the absolute value of num1 minus the value of num2. This could be negative, while in the code segment diff is always positive.
II only
I, II, and III
III only

What are procedures that keep a data base current

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; }};
