Question Discussion & Solution

Statement: x /= 2,

It is compound assignment statement. It is basically a shorthand notation for incrementing the variable on the left by a value on the right.

So, x /= 2 is same as x = x / 2.

Similarly

X -= 2; is the same as x = x – 2 ;

 x*=2; is the same as x=x*2;

Therefore, in given question all the options are 1, 2, 4 are correct. As there are using the compound assignment operators.

But in option 3 x%=2 is not same as x = x/2 as the operators are different.

X%=2 is same as x = x%2
