Understanding Subprograms in Programming

The video tutorial explains the importance of using subprograms in programming, particularly functions and procedures, to enhance code reliability and ease of testing. It highlights the problems associated with code duplication and demonstrates how to create a procedure in Python. The tutorial also discusses the benefits of subprograms, such as code reuse, faster development, and reduced bugs. Additionally, it covers the use of subprograms in pseudocode, emphasizing the logical organization of code for better readability and maintenance.

What is the primary difference between functions and procedures?

• Functions can return values, procedures cannot.

• Procedures are faster than functions.

• Procedures can return values, functions cannot.

• Functions are used for input, procedures for output.

Why is copying and pasting code multiple times problematic?

• It is difficult to read.

• It requires more memory.

• It increases the risk of inconsistencies and bugs.

• It makes the code run slower.

What keyword is used to define a procedure in Python?

• function

• def

• return

• procedure

What happens when you run a program with a function that hasn't been called?

• The program will display an error message.

• Nothing happens until the function is called.

• The function will execute automatically.

• The program will crash.

What is a common use of parameters in functions?

• To pass data into the function.

• To create loops.

• To print data to the console.

• To store data permanently.

How do subprograms help in reducing bugs in a program?

• By increasing the number of variables.

• By making the code longer.

• By allowing code reuse and reducing the number of lines.

• By making the code more complex.

What is one of the main advantages of using subprograms in development?

• They allow for faster development by reusing code.

• They make the code harder to read.

• They increase the number of errors.

• They slow down the development process.

Why is it beneficial to break up code logically into subprograms?

• It makes the code easier to read and maintain.

• It makes the code harder to test.

• It complicates the debugging process.

• It increases the number of lines of code.

In pseudocode, what keyword is used to define a procedure?

• def

• function

• procedure

• return

What must a function include in its code to differentiate it from a procedure?

• A loop

• A return statement

• An input statement

• A print statement
