Question

a) void printtodaysdate();
b) string printtodaysdate();
c) int printtodaysdate();
d) printtodaysdate();

Answer 1

The correct statement to declare a prototype for the function printtodaysdate is option (a): void printtodaysdate();. This indicates that the function will not return any value and takes no parameters.

Step-by-step explanation:

The correct option for declaring a prototype for a function named printtodaysdate that has no parameters and does not return anything is option (a): void printtodaysdate();. In programming, especially in C and C++ languages, the keyword void is used to indicate that a function does not return a value. Therefore, the prefix void is used in the function declaration to denote that the function will perform an action, like printing today's date to the console, but it will not return any value back to the caller.

The syntax for declaring a function prototype includes the return type (void in this case), the function name (printtodaysdate), and a set of parentheses which would contain parameters if there were any. Since this particular function takes no parameters, the parentheses are empty.
