Question
1)
a) The following code was written to declare a dynamic two-dimensional array with 10 rows and 4 columns, but it is incorrect! Correct it below.
int **matrix = new int matrix[10];
int i;
for (i = 0; i < 4; i++)
matrix[i] = new int[10];
b) Write the code to free (deallocate) the two-dimensional array from part a) above.
2)
Here is a class
class movieInfo
{
private:
int numActors; //number of Actors on the list
string * actorList; //holds all the actor names
string director;
public:
void printActors() const; //prints all the actors
void readActors(); //gets actor names from cin
void setDirector(string); //sets the director name
string getDirector() const; //returns the director name
movieInfo(); //sets empty actorList
movieInfo(int); //sets numActors to int parameter
a ) Write the prototype and defintion for a member function called sharesDirector. This function returns true if two movies have the same director and returns false otherwise.
prototype:____________________________________________________________
definition:
b) Write the prototype and defintion for a member function calles sharesActors. This function returns the number of shared actors (i.e. the count of actors that are in both movies.) If there are no actors that are in both movies, then the function returns a zero.
prototype:____________________________________________________________

Explanation / Answer
1) a) int **matrix = new int matrix[10];
int i;
for (i = 0; i < 10; i++)
matrix[i] = new int[4];
b)
2)
a)
prototype: bool sharesDirector(movieInfo a, movieInfo b);
defination: bool movieInfo :: sharesDirector(movieInfo a, movieInfo b){
if(a.getDirector().compare(b.getDirector())==0)
return true;
else
return false;
}
