In the expression 'j %= k;', given that j and k are integers, what does this operation do?

  1. Divides j by k and assigns the remainder to j

  2. Multiplies j and k and assigns the result to j

  3. Subtracts k from j and assigns the result to j

  4. Adds j and k and assigns the result to j

The correct answer is: Divides j by k and assigns the remainder to j

In this expression, the '%=' operator is known as the modulus operator. This operation returns the remainder of dividing j by k, and then assigns that value to j. Therefore, option A is the correct answer. Option B is incorrect because the multiplication operator is '*', not '%='. Option C is incorrect because the subtraction operator is '-', not '%='. Option D is incorrect because the addition operator is '+', not '%='.
