1. Function Procedure - A procedure that returns a value explicitly. 2. Sub Procedure - A procedure that does not return any value explicitly. Here is simple example of defining a function procedure, invoking a procedure, and exchanging data with a procedure: ...
if you wanted to check that both a user's age is above eighteen (18) and their name is “John Doe”, then this could be written as an expression like: if (age > 18, name == “John Doe”). This type of syntax ensures that both conditions must be true in order for the program...
