Question

Please refer to the following code when answering questions 1 through 3:

#include <stdio.h>

int main() {

int a = 5, b = 7, c = 2;

a = 2*b + c;

printf("a = %d, b = %d, c = %d ", a, b, c);

b = 2*c + a;

printf("a = %d, b = %d, c = %d ", a, b, c);

c = 2*a + b;

printf("a = %d, b = %d, c = %d ", a, b, c);

return 0;

}

1) What is the first line of output of the program above?

a) a = 5, b = 7, c = 2 b) a = 16, b = 7, c = 2

c) a = 9, b = 7, c = 2 d) a = 12, b = 7, c = 2

2) What is the second line of output of the program above?

a) a = 16, b = 9, c = 2 b) a = 9, b = 9, c = 2

c) a = 16, b = 20, c = 2 d) a = 16, b = 9, c = 7

3) What is the third line of output of the program above?

a) a = 16, b = 9, c = 17 b) a = 16, b = 9, c = 41

c) a = 16, b = 20, c = 49 d) a = 16, b = 20, c = 56

4) What is the output produced by the code segment below?

int a = 3, b = 7;

if (2*a > b || b < 3*a)

printf("A");

if (2*a > b && b < 10*a)

printf("B");

else

printf("C");

a) A b) B c) AB d) AC

5) What is the output produced by the code segment below?

int a = 4, b = 6;

if (a > b)

if (!b)

printf("A");

else

printf("B");

printf("C");

a) A b) B c) AC d) BC

6) What is the output produced by the code segment below?

int grade = 88;

if (grade >= 60) printf("D");

if (grade >= 70) printf("C");

if (grade >= 80) printf("B");

if (grade >= 90)

printf("A");

else

printf("F");

a) DCBF b) DCB c) B d) D

7) What is the output produced by the code segment below?

int i, sum;

sum = 0;

for (i=3; i<10; i+=3)

sum += i;

printf("i = %d, sum = %d ”, i, sum);

a) i = 9, sum = 9 b) i = 9, sum = 18

c) i = 12, sum = 18 d) i = 12, sum = 30

8) What is the output produced by the code segment below?

int i, sum;

sum = 0;

for (i=3; i<10; i+=3); // Last semicolon is intentional.

sum += i;

printf("i = %d, sum = %d ”, i, sum);

a) i = 9, sum = 9 b) i = 12, sum = 12

c) i = 12, sum = 18 d) i = 12, sum = 30

Explanation / Answer

Question 1:

#include <stdio.h>

int main() {

int a = 5, b = 7, c = 2;

a = 2*b + c;

printf("a = %d, b = %d, c = %d ", a, b, c);

b = 2*c + a;

printf("a = %d, b = %d, c = %d ", a, b, c);

c = 2*a + b;

printf("a = %d, b = %d, c = %d ", a, b, c);

return 0;

}

Answer: 1) B 2) C 3) D (d) a = 16, b = 20, c = 52) Note: C= 52 here not 56, option wrong,

Question 2:

int a = 3, b = 7;

if (2*a > b || b < 3*a)

printf("A");

if (2*a > b && b < 10*a)

printf("B");

else

printf("C");

Answer: C --- AC

Question 3:

int a = 4, b = 6;

if (a > b)

if (!b)

printf("A");

else

printf("B");

printf("C");

Answer: it should print value C but i dont see this option in your option.

Question 4:

int grade = 88;

if (grade >= 60) printf("D");

if (grade >= 70) printf("C");

if (grade >= 80) printf("B");

if (grade >= 90)

printf("A");

else

printf("F");

Answer: A --- DCBF

Question 5:

int i, sum;

sum = 0;

for (i=3; i<10; i+=3)

sum += i;

printf("i = %d, sum = %d ”, i, sum);

Answer: c) i = 12, sum = 18

Question 6:

int i, sum;

sum = 0;

for (i=3; i<10; i+=3); // Last semicolon is intentional.

sum += i;

printf("i = %d, sum = %d ”, i, sum);

Output: b) i = 12, sum = 12
