Method 1: Using compare (“==”) operator. In this method, we check if a number is complex by comparing it with itself. If the result is true, then the number is not complex i.e., real. But if the result is false, then “nan” is returned, i.e. the number is complex. CPP #include #include council tax reform scotland https://sexycrushes.com
