Question

1. State true or false: (6 x 2 = 12 pts)

1. Using -- with a reverse iterator moves it from the back toward the front of a list

b) The body of a do-while loop is always executed at least once.

c) If p points to the array element a[j], then p + i points to a[i+j].

d) Any number of pointer variables may point to the same object.

5. In terms of both execution speed and memory usage usually iterative solutions are better than recursive solutions.
6. The condition (k > c) performs the same test as (-k < -c) where k and c are non-zero integers.

2. State True/False (8 pts)

struct Point

{

   int x, y;

};

        struct Line

{

   Point a, b;

};

       Line image[10];

1. image is an array

b) image[6] is an struct

   c) image[6].a is a array

      d) image[6].a.x is a struct

7. Multiple choice problems: (5 x 2 = 10 pts)

Which of the following statements correct about k used in the below statement? char ****k;

A. k is a pointer to a pointer to a pointer to a char B. k is a pointer to a pointer to a pointer to a pointer to a char C. k is a pointer to a char pointer D. k is a pointer to a pointer to a char

Which of the statements is correct about the program? #include<stdio.h> int main() {     int i=10;     int *j=&i;     return 0; }

A. j and i are pointers to an int B. i is a pointer to an int and stores address of j C. j is a pointer to an int and stores address of i D. j is a pointer to a pointer to an int and stores address of i

3. Assume a float requires 4 bytes. How many bytes does the following array require?

float scores[20];

A. 20                 B. 76               C. 80                D. 84                E. None of the above

4. Assuming int x = 2, y = 3, z = 4; what is the value of x - y * y / z ?

A. 0   B. 0.5           C. 0.25                  D. -0.25    E. None of the above

5. What is value of the variable prod after the following code segment has been executed?

            prod = 1;

            for (count = 3; count < 6; count++)

                 prod *= count;

         A. 3         B. 60    C. 120   D. 360        E. 840
