The student is not correct. Integers are whole numbers, while real numbers can be decimals or fractions. For example, 0.4 + 1.2 = 1.6 which is not a whole number, so it is not an integer.

Try to think of a counterexample to prove them wrong! Not all real numbers are integers… choose one that's not and add it to another real number.
