Question

Please help me with these short questions?

Suppose that p is an int* variable. Write several lines of code that will make p point to an array of 100 integers, place the numbers 0 through 99 into the array components, and return the array to the heap.

What happens if you call new but the heap is out of memory?

Draw a picture of memory after these statements:
    int i = 42;
    int k = 80;
    int* p1;
    int* p2;
    p1 = &i;
    p2 = &k;
Suppose that we execute the statements from the previous question, and then we execute these statements:
    *p1 = *p2;
Draw a picture of memory after this additional statement.

Draw a picture of memory after these statements:
    int i = 42;
    int k = 80;
    int* p1;
    int* p2;
    p1 = &i;
    p2 = &k;
    p1 = p2;

Here is a function prototype:
    void exam (const double data[]);
Write two or three sentences to tell me all the information that you know about the parameter.

B. When the function changes p, and you do NOT want the change to affect the actual pointer argument.
C. When the function changes *p, and you want the change to affect the the object that is pointed at.
D. When the function changes *p, and you do NOT want the change to affect the the object that is pointed at.
E. When the pointer points to a large object.

Suppose you have the following function prototype and variable declaration:
    void goop(int z[ ]);
    int x[10];

A. goop(x);
B. goop(x[ ]);
C. goop(x[10]);
D. goop(&x);
E. goop(&x[ ]);

A. Yes
B. No

Here is a function declaration:
    void goo(int* x)
    {

Explanation / Answer

According to chegg guidelines i have to solve first four bits but i solve all bits(Multiple choice questions).

1.

Consider the following statements:
    int *p;
    int i;
    int k;
    i = 42;
    k = i;
    p = &i;
After these statements, which of the following statements will change the value of i to 75

Option D correct

2.

Consider the following statements:
int i = 42;
   int j = 80;
   int *p1;
   int *p2;
   p1 = &i;
   p2 = &j;
   *p1 = *p2;
   cout << i << j << endl;

Option D correct

3.

Option C correct

6.

Which is the correct way to call the goop function with x as the argument:

Option A correct

7.

Suppose that the goop function from the previous question changes the value of z[1]. Does this change affect the value of the actual argument

Option A correct

8.

Here is a function declaration:
    void goo(int* x)
