What will be the content of y and z after executing the code given below: int y=10, z=2; for (int x = 1; x <= 10; x=x+2)

Question

{ y - - ;
++z;
}

Answer 1

iteration 1:
y = 10
z = 2

x = 1 and is less than or equal to 10
so,
y--;
++z;
so y becomes 9
and z becomes 3
and x = x + 2 = 1 + 2 = 3

iteration 2:
y = 9
z = 3

x = 3 and is still less than or equal to 10
so,
y--;
++z;
so y becomes 8
and z becomes 4
and x = x + 2 = 3 + 2 = 5

iteration 3:
y = 8
z = 4

x = 5 and is less than or equal to 10
so,
y--;
++z;
so y becomes 7
and z becomes 5
and x = x + 2 = 5 + 2 = 7

iteration 4:
y = 7
z = 5

x = 7 and is less than or equal to 10
so,
y--;
++z;
so y becomes 6
and z becomes 6
and x = x + 2 = 7 + 2 = 9

iteration 5:
y = 6
z = 6

x = 9 and is less than or equal to 10
so,
y--;
++z;
so y becomes 5
and z becomes 7
and x = x + 2 = 9 + 2 = 11

iteration 6:
y = 5
z = 7
and x = 11
now the for loop block won't be executed because the for loop condition fails. (x<=10) that is 11 is not less than or equal to 10

Thank you so much
