Declare an enumerated type month_t and rewrite the following if statement, assuming that cur_month is type month_t instead of type int . Also, write the equivalent switch statement. if (cur_month == 1) printf("Happy New Year\ n"); else if (cur_month == 6) printf("Summer begins\ n"); else if (cur_month == 9) printf("Back to school\ n"); else if (cur_month == 12) printf(" Happy Holidays\ n");
