Question

Write the definition of a function isEven, that receives an integer parameter and returns true if the parameter's value is even, and false otherwise. So, if the parameter's value is 7 or 93 or 11 the function returns false. But if the parameter's value is 44 or 126 or 7778 the function returns true.
