Description:
I need help with the following:

1. Which could NEVER be a valid function header in C++? (function header = 1st line of member or non-member function definition.)

(a) void conic (float f = 3., float x, int i = 9)

(b) void conic (void)

(c) void Super::conic (float f = 3., int i = 9)

(d) void Super::conic (void)

(e) void conic (float f = 3., int i )

2. Which could be used to get a multiple-word string from user at the console? Assume that the variable "user" is large enough to hold whatever the user types in, and assume that the user types in less than 79 characters.

(a) fgets(user, 79, stdin);

(b) gets(user);

(c) cin >> user;

(d) cin << user;

(e) gets(user, 79, stdin);

3. If << and >> have not been overloaded by the programmer (that is, they only have their usual C++ meanings), which is/are INCORRECT?

(a) cout << x << y << z;

(b) cout >> 3.6 >> "\n";

(c) cout >> cin;

(d) cin >> x >> y;

(e) cout << x; cin >> y;

Deliverables:
4. The class Amine has a member function dopamine whose prototype is:

class Amine
{
...
double dopamine (double x);
...
};

and the definition has no default parameters. Which of the following could NOT be the definition of this member function?

(a) double Amine::dopamine (double x)
{
joe=x; return joe;
}

(b) double Amine::dopamine(double x)
{
double joe;
return (joe = x);
}

(c) double Amine::dopamine (double x)
{
return 5. ;
}

(d) double dopamine(double x)
{
double joe;
joe = x;
return joe;
}

(e) double Amine::dopamine ()
{
return 0. ;
}

5. Consider:
int ar[] = {2, 5, 3, 2, -1};
int *ar2;

Check the statements that are problematic, based on these declarations. For each statement below, assume that it follows the declarations immediately with no intervening statements.
In other words, only one of the statements below would occur in the program.

(a) ar2 = ar;

(b) ar2[3] = 7;

(c) ar[5] = 99;

(d) ar[3] = ar[4];

(e) cin >> ar[3];

6. Member function fourier() has 3 overloaded variants. The first two prototypes are shown:

class Transform
{
...
public:
int fourier();
int fourier(int n);
...
};

Which could not represent the 3rd overloaded prototype of this function name?

(a) int fourier (Transform *t);

(b) int fourier (Transform *t, int n=2);

(c) int fourier (int n, float f);

(d) int fourier (Transform *t = NULL);

(e) void fourier (int n);

I NEED THE ANSWERS TO THESE ASAP FOR MY HOMEWORK DUE TONIGHT!!!
