Answer:
printtodaysdate()
Step-by-step explanation:
Not sure which language it's asking about specifically, but generally you'll call a function like this: "functionName(arguments)", and since it accepts not parameters, nothing will be inside the parenthesis. sine it also has no return value, you won't assign it to some other variable (this is not really necessary, of course if you need the return value then yeah I guess). so the statement is most likely just: "printtodaysdate()"
