Question

x, y, z, w, u and t are integer variables, what will their value be after the execution of the statements below. Give the final value of each variable

x = 7;

y = x + 1;

z = x % (y – 2) + 4;

y = (y + z ) % (x + 4) ;

w = (x * y) / (z – 3);

x = x + x;

u = w - 3;

t = z + (x + y + 2) % w;

Answer 1

1) x=7

2) y= x+1

y=7+1

y=8

3) z = x % (y – 2) + 4;

z = 7%(8-2)+4; (here () is higher precedence so first calculate the values whith in braces.)

z = 7%6+4; (Here % is higher precedence so first first we do modulo operation)

z= 1+4

z=5

4) y = (y + z ) % (x + 4) ;

y = (8 + 5) % (7 +4); (Here () is higher precedence so first calculate the values whith in braces. precedence is left to right)

y = 13%11

y = 2 (Now the value of y is updated to 2 from 8)

5)  w = (x * y) / (z – 3);

w = ( 7*2)/(5-3);

w = 14 / 2

w =7

6) x = x + x;

x= 7 + 7

x = 14 (Now the value of x is updated to 14 from 7)

7)  u = w - 3

u = 7-3

u = 4

8) t = z + (x + y + 2) % w

t = 5 + ( 14 + 2+ 2) % 7 (Here () have higher precedence than % and +)

t = 5 +18 %7 (Here % have higher precedence than +,so first we do % operation)

t = 5+4

t =9

The value of x is : 14

The value of y is : 2

The value of w is : 7

The value of z is : 5

The values of u is : 4

The value of t is : 9
