Programming Concepts Quiz

Why is it important to have a solid understanding of basic programming concepts before watching this video?

• To skip the video content

• To avoid learning programming

• To memorize programming languages

• To better understand modularity and parameter passing

What is the main goal of modularity in programming?

• To make programs more complex

• To make programs run faster

• To break down a program into smaller, manageable parts

• To increase the number of lines of code

How does a function differ from a procedure?

• Neither return values

• A function returns a value, while a procedure does not

• A procedure returns a value, while a function does not

• Both return values

In the C# example, what does the sqrt function do?

• Calculates the square root of a number

• Calculates the square of a number

• Adds two numbers

• Subtracts two numbers

What is the purpose of the 'by val' keyword in Visual Basic?

• To end a procedure

• To declare a variable

• To pass parameters by value

• To pass parameters by reference

What happens when a parameter is passed by value?

• The original variable is modified

• A copy of the variable is passed

• The program crashes

• The variable is deleted

How does passing by reference differ from passing by value?

• Passing by reference creates a copy of the variable

• Passing by reference uses a pointer to the original variable

• Passing by value uses a pointer to the original variable

• Both methods create a copy of the variable

What is considered bad practice in modern programming regarding parameter passing?

• Passing by value

• Passing by reference with implicit dependencies

• Using too many functions

• Not using procedures

In modern programming, what is typically stored separately on the heap?

• Variable names

• Object data

• Function names

• Primitive data types

What is the net effect of passing a reference in modern programming?

• It is always the same as passing by reference

• It has no effect on the program

• It can be the same as either passing by value or reference

• It is always the same as passing by value
