1. int a = 10, b, c, d;

a. compute d = b = c = a

b. compute d = a / 3

c. compute d = a%3

2. int a = 10, b;

a. compute b = a/3

3. What is y displayed in the following code?

#include using namespace std;

int main()

{ int x = 1; int y = x = x - 1;

cout << "y is " << y;

return 0;

}

4. int a =10, b = 20; c = 10, d;

a. compute d = (++a) + b c

b. compute d = a (b--) + (++c)

5. int a = 10, b = 11, c = 167, d; (Take 8-bit binary representation)

a. compute d = a&b

b. compute d = a|(b&c)

c. compute d = (a==b)

d. compute d = (a>=b)

e. compute d = ((a&b)|c)

f. compute d = (a&(~b))

6. What will be the value of the variable d in the statement given below if x, y, and z are int variables, and x = 10, y = 15, and z = 20. You can give the results in 1 and 0 or true and false (true means 1 and false means 0).

d = (x <= z % y - 2) && (y >= z)

7. int a = 100, b = 11, c;

a. compute c = a<<2

b. compute c = b<<2

8. Suppose that x = (2B6E)_{16 ,} y = (5AE9)₁₆ and _Z = (27BC)₁₆ and Solve the expression = (x|~y&~z) and return the result in hexadecimal.

9. int a = 110, b = 10, c;

a. compute c = (a==100) ? b : a

10. int a = 100, b = 10, c = 34; d;

a. compute d = (a / b)* c + ((c *b) a) / b

b. compute d = (a % b)* c + ((c *b) a) / b

c. compute d = (a / b)* c - ((c %b) a) / b

11. int a = 100; char b; float c = 3.5; int d;

a. compute d = sizeof(a);

b. compute d = sizeof(b);

c. compute d = sizeof(c)

12. Sort the following binary operators in order of high to low precedence: +, -, *, /, %, =.

13. What is printed by the following code snippet? int x1 = 2, y1, x2 = 2, y2; y1 = ++x1; y2 = x2++;

cout << x1 << " " << x2 << ' '; cout << y1 << " " << y2 << ' ';

--x2; y1 = x2++; x1++; y2 = x1--;

cout << x1 << " " << x2 << ' '; cout << y1 << " " << y2 << ' ';

14. What is the value of variables a, b, and c in the program below after the statement 1, 2, and 3. Please fill-up the values of a, b, c in the table given below after each statement (1, 2 and 3) is executed.

int a = 5; int b = 6;

int c;

a = (b++) + 3; // Statement 1

c = 2 * a + (++b); // Statement 2

b = 2 * (++c) - (a++);// Statement 3

15. Consider the following section of C++ code:

#include stdafx.h #include using namespace std;

int main() {

int m = 3, n = 2, x , y;//Variable declarations and initializations x = m + 5; m--;

y = (m + 4)/3;

n = (n--) + 2;

m = m + n/2;

m++;

x = (--x) * 2 - 3;

y = y * 2;

n = n + y * 3;

cout << "m = " << m << endl; // Statement -1 for output printing

cout << "n = " << n << endl; // Statement -2 for output printing

cout << "x = " << x << endl; // Statement -3 for output printing

cout << "y = " << y << endl; // Statement -4 for output printing return 0;

}

What will be the value of variables m, n, x and y as printed in the statement -1, statement -2, statement -3 and statement -4?
