What is the output from this program? #include void do_something(int *thisp, int that) { int the_other; the_other = 5; that = 2 + the_other; *thisp = the_other * that; } int main(void) { int first, second; first = 1; second = 2; do_something(&second, first); printf("%4d%4d\n", first, second); return 0; } A) 35 2 B) 1 35 C) 35 7 D) 1 2 E) 0 3. In function apart defined below, how many of the parameters are considered input parameters? void apart(double x, int *wholep, double *fracp) { *wholep = (int)x; *fracp = x - *wholep; } A) 0 B) 1 C) 2 D) 3 E) all 4. Variables that represent neither problem inputs nor problem outputs but are needed for internal computations are called _____. A) problem constants B) prototypes C) results D) formula variables E) program variables 5. This question concerns the following program fragment: char r, x, y, z, w; scanf("%c%c%c%c", &x, &y, &z, &w); if (x < y) r=x; else r=y; if (r>z) r=z; if (r>w) r=w; printf("%c\n", r); The program's effect can best be described as: A) It displays the letter 'r' after comparing it to x, y, and z. B) Of the four input characters, it displays the one that comes first in the alphabet. C) Of the four input characters, it displays the one that comes last in the alphabet. D) Of the four input characters, it displays the one that comes second in the alphabet. E) It displays nothing since characters cannot be compared. 6. In a function that receives a value from the main function via a parameter and then displays the parameter value on the screen, that parameter is considered __________. A) an input parameter B) an output parameter C) an input/output parameter D) a local variable E) a stub 7. What is the complement of the following expression? n||a <= b && c != 100 A) !n || a > b || c == 100 B) !(n && (a > b || c == 100)) C) !n && (a > b || c == 100) D) !(n || (a > b || c == 100)) E) none of the above 8. The if statement: if (13 < 12) printf("never\n"); else printf("always\n"); A) displays never. B) displays always. C) will not compile since 13 is not less than 12.

How many lines of output will be displayed by the following program fragment? i=0; do { for (j = 0; j < 4; j = j + 1) printf("%d\n", i + j); i=i + 1; } while (i < 5); A) 0 B) 7 C) 9 D) 16 E) 20 10.
