class Foo {
const int x;
protected:
Foo(int f);
~Foo();
};
Foo f;
Referring to the sample code above, why will the class
declaration not compile?
a) The variable x is const.
b) The destructor is protected.
c) The destructor is not public.
d) The constructor is protected.
e) There is no default constructor.
class X
{
private:
int a;
protected:
X(){cout<<"X constructor was called"<<endl;}
~X(){cout<<"X destructor was called"<<endl}
};
Referring to the code above, which one of the following
statements regarding "X" is TRUE?
a) X is an abstract class.
b) Only subclasses of X may create X objects.
c) Instances of X cannot be created.
d) X objects can only be created using the default copy
constructor.
e) Only friends can create instances of X objects.
class HasStatic {
static int I;
};
Referring to the sample code above, what is the appropriate
method of defining the member variable "I", and assigning it
the value 10, outside of the class declaration?
a) HasStatic I = 10;
b) int static I = 10;
c) static I(10);
d) static I = 10;
e) int HasStatic::I = 10;
class Foo {
int x;
public:
Foo(int I);
};
If a class does not have a copy constructor explicitly
defined one will be implicitly defined for it. Referring to
the sample code above, which one of the following
declarations is the implicitly created copy constructor?
a) Foo(Foo *f);
b) Foo(Foo &f);
c) Foo(const Foo *f);
d) Foo(const Foo &f);
e) Foo(int);
class Alpha {
public:
char data[10000];
Alpha();
~Alpha();
};
class Beta {
public:
Beta() { n = 0; }
void FillData(Alpha a);
private:
int n;
};
How do you make the above sample code more efficient?
a) If possible, make the constructor for Beta private to
reduce the overhead of public constructors.
b) Change the return type in FillData to int to negate the
implicit return conversion from "int" to "void".
c) Make the destructor for Alpha virtual.
d) Make the constructor for Alpha virtual.
e) Pass a const reference to Alpha in FillData
class basex
{
int x;
public:
void setx(int y) {x=y;}
};
class derived : basex {};
What is the access level for the member function "setx" in
the class "derived" above?
a) private
b) local
c) global
d) public
e) protected
string somestring ;
Which of the following choices will convert a standard C++
string object "somestring" to a C string?
a) Copy.somestring () ;
b) somestring.c_str ()
c) &somestring [1]
d) std::cstring (somestring)
e) (char *) somestring
class professor {};
class teacher : public virtual professor {};
class researcher : public virtual professor {};
class myprofessor : public teacher, public researcher {};
Referring to the sample code above, if an object of class
"myprofessor" were created, how many instances of professor
will it contain?
a) 0
b) 1
c) 2
d) 3
e) 4
1. What does the following do:
void afunction(int *x)
{
x=new int;
*x=12;
}
int main()
{
int v=10;
afunction(&v);
cout<<v;
}
a) Outputs 12
b) Outputs 10
c) Outputs the address of v

Am studying basic c++ programming, have been given the
following assignment. Design a linear program to calculate
the maximum stress a material can withstand given a force
and a diameter of a circle. To find the required area pi
should be defined.
Have most of the program sorted out but am at a loss as to
how to show the calculations required. Can anyone help?
If P is the population on the first day of the year, B is
the birth rate, and D is the death rate, the estimated
population at the end of the year is given by the formula:
The population growth rate is given by the formula:
B – D
Write a program that prompts the user to enter the starting
population, birth and death rates, and n, the number of
years. The program should then calculate and print the
estimated population after n years. Your program must have
at least the following functions:
1. growthRate: This function takes its parameters the
birth and death rates, and it returns the population growth
rate.
2. estimatedPopulation: This function takes its
parameters the current population, population growth rate,
and n, the number of years. It returns the estimated
population after n years
Your program should not accept a negative birth rate,
negative death rate, or a population less than 2.
please answer my question ....
