Problem Solving and Program Design

What is the first step in the problem-solving process?

• Propose solutions

• Define the problem

• Test and validate the solution

• Develop the algorithm

Which of the following is NOT part of the divide-and-conquer approach?

• Breaking a large problem into smaller tasks

• Solving each smaller task individually

• Defining the problem in one large statement

• Managing tasks in a structured manner

What does IPO stand for in problem-solving?

• Input, Process, Output

• Input, Performance, Output

• Indicate, Process, Operate

• Input, Produce, Output

Which of the following is a valid variable name in most programming languages?

• 1stPlace

• total_Score

• #score

• break

What is a constant in programming?

• A value that can change during the program

• A value that cannot be changed once defined

• A function that runs repeatedly

• A statement that ends the program

Which of these is a valid example of a constant?

• studentName

• totalAmount

• pi = 3.14159

• score = 0

What is the purpose of testing and validating a solution?

• To add new features to the solution

• To check if the solution works as intended

• To break the solution into smaller tasks

• To update the problem definition

In which of the following situations should you use the divide-and-conquer approach?

• When you have a simple problem that can be solved in one step

• When you need to manage complex problems that involve multiple tasks

• When you are writing a short program

• When you have already defined the problem

Which data type is used to store true or false values?

• Integer

• String

• Boolean

• Character

Which of the following is a valid algorithm step?

• Create an ambiguous process

• Have an infinite number of steps

• Use imprecise instructions

• Perform a clear and finite set of steps
