Answer:

A key field is used to uniquely identify each record for retrieval or manipulation.

Explanation:

In a database there are many, having similar entities. So in order to differentiate each entity from other we need to set a key field among all the field which is always unique for each entity.

Answer:

d. integrity

Explanation:

Data integrity is defined as the condition in which all of the data in the database are consistent with the real-world events and conditions.

Data integrity can be used to describe a state, a process or a function – and is often used as a proxy for “data quality”. Data with “integrity” is said to have a complete or whole structure. Data integrity is imposed within a database when it is designed and is authenticated through the ongoing use of error checking and validation routines. As a simple example, to maintain data integrity numeric columns/cells should not accept alphabetic data.

GamePoints::GamePoints() :

/* Your code goes here */

{

teamLions = 500;

teamDolphins = 500;

}

Here is the complete program:

#include  //to use input output functions

using namespace std; //to identify objects like cin cout

class GamePoints {  //class GamePoints

   public: GamePoints(); // constructor of GamePoints class

   void Start() const;  //method of GamePoints class

   private: //declare data members of GamePoints class

   int teamDolphins; // integer type private member variable of GamePoints

   int teamLions; }; // integer type private member variable of GamePoints

   GamePoints::GamePoints()  //constructor

    { teamLions = (500), teamDolphins= (500); }   //assigns 500 to the data members of teamLions  and teamDolphins of GamePoints class

   void GamePoints::Start() const    { //method Start of classs GamePoints

       cout << "Game started: Dolphins " << teamDolphins << " - " << teamLions << " Lions" << endl; }  //displays the values of teamDolphins and teamLions i.e. 500 assigned by the constructor

       int main() //start of main() function

       { GamePoints myGame;  // creates an object of GamePoints class

       myGame.Start(); //calls Start method of GamePoints class using the object

       return 0; }

The output of the program is:

Game started: Dolphins 500 - 500 Lions
