Question

4. Consider the following declarations ;

char c = ‘a’;

byte b = 1;

short s = 2;

int i = 3; long l = 4;

float f = 5.0f;

double d = 6.0;

Indicate the value which is assigned to the LHS of the assignment statement in each of the following.

a. i = b + 2 * s / 2 + i;

b. i = (b + 2 * s) / (2 + i);

c. i += (b + 2 * s) / 2 + i;

d. i += (b + 2 * s) / 2.0 + i;

e. c = (char)(c + 1);

f. i += b++ + ++i;

g. i = ++b * s++;

h. i = – – i + i – –;

Answer 1

a. i = b + 2 * s / 2 + i;
i = 6

b. i = (b + 2 * s) / (2 + i);
i = 0

c. i += (b + 2 * s) / 2 + i;
i = 2

d. i += (b + 2 * s) / 2.0 + i;
i = 6

e. c = (char)(c + 1);
c = b

f. i += b++ + ++i;
i = 14

g. i = ++b * s++;
i = 6

h. i = – – i + i – –;
i = 10
