Prototype Declaration :

void message();

Void Data Type -
[arrowlist]

• void means empty.
• void data type means function does not return anything.
• So we dont have to assign function call to any variable.

[/arrowlist] we don’t need to do -

num = message();

instead of this simply call function like this -

message();
