Understanding Parameters in Subprograms

Why are parameters important in subprograms?

• They help in debugging the code.

• They allow functions to be more versatile and useful.

• They make the code run faster.

• They reduce the size of the code.

What must you include when calling a function?

• The function name and a colon.

• Only the function name.

• The function name and a pair of brackets.

• The function name and a semicolon.

What is the purpose of brackets when defining a function?

• To call another function.

• To start a loop.

• To include parameters.

• To indicate the end of the function.

What happens to the value passed into a function parameter?

• It is ignored.

• It is printed to the screen.

• It is stored in a global variable.

• It is used within the function as a local variable.

In the example, what does 'num to add' represent?

• A function name.

• A global variable.

• A parameter name.

• A constant value.

What is the result of calling the function 'Adder' with the parameter 7?

• The function will return 0.

• The function will return 10.

• The function will not run.

• The function will return 7.

How can you make a function behave differently?

• By calling it multiple times.

• By changing its name.

• By passing different parameters.

• By using a different programming language.

What does the 'return' statement do in a function?

• It stops the function from running.

• It passes a value back to the main program.

• It prints a value to the screen.

• It calls another function.

How do you capture the value returned by a function?

• By using the 'print' statement.

• By calling the function again.

• By assigning it to a variable.

• By using a global variable.

What will be the output if 'result' is printed after calling 'Adder' with 9?

• 3

• 9

• 7

• 0
