I need the answer to teh following questions for my c++ course:

1.

Provide the required line of code that is missing from this function.

int divide (int a, int b=2) { int r; r=a/b; //missing statement goes here } 

2. You have the following struct defined in the private area of your class called myClass:

struct database { int id_number; int age; float salary; };

Your class has a member function called setID that is implemented below. Provide the missing line of code to set the struct's id_number variable equal to the value passed to this function when it is called.

void myclass::setID(int id) { database employee; _______________________ } 

Note: Do not put spaces in your answer.
