8.4 App Design Review

Which of the following symbols is used to represent a decision in a flowchart?

• Oval

• Diamond

• Rectangle

• Parallelogram

What is the primary purpose of using pseudo-code in computer application design?

• To execute the program

• To provide a detailed, language-specific code

• To outline the logic of the program in plain language

• To create a visual representation of the program flow

Identify the correct sequence of steps in a flowchart for a simple "if-else" decision-making process.

• Start -> Process -> Decision -> End

• Start -> Decision -> Process -> End

• Start -> Decision -> Process -> Decision -> End

• Start -> Process -> Decision -> Process -> End

Convert the following pseudo-code into a flowchart: ``` If temperature > 30 Print "It's hot" Else Print "It's cool" ```

• Use a diamond for the decision and rectangles for the print statements.

• Use ovals for the decision and diamonds for the print statements.

• Use rectangles for both decision and print statements.

• Use parallelograms for the decision and rectangles for the print statements.

Explain why pseudo-code might be preferred over flowcharts in some scenarios.

• Pseudo-code is more visually appealing.

• Pseudo-code is easier to convert into actual code.

• Pseudo-code requires less memory to store.

• Pseudo-code is universally understood by all programmers.

Given a flowchart with a loop, how would you represent this in pseudo-code?

• Use "if" statements to represent the loop.

• Use "while" or "for" loops to represent the iteration.

• Use "switch" statements to represent the loop.

• Use "goto" statements to represent the loop.

Which of the following is a limitation of using flowcharts?

• They are difficult to understand.

• They cannot represent complex logic.

• They are not suitable for large programs.

• They are not useful for debugging.

Create a pseudo-code for a program that calculates the sum of numbers from 1 to 10.

• Initialize sum to 0; For each number from 1 to 10, add to sum; Print sum.

• Initialize sum to 0; While number is less than 10, add to sum; Print sum.

• Initialize sum to 0; For each number from 1 to 10, subtract from sum; Print sum.

• Initialize sum to 0; For each number from 1 to 10, multiply to sum; Print sum.

Compare the effectiveness of flowcharts and pseudo-code in documenting a program's logic.

• Flowcharts are more effective because they are visual.

• Pseudo-code is more effective because it is closer to actual code.

• Both are equally effective in all scenarios.

• The effectiveness depends on the complexity and size of the program.

Which flowchart symbol is used to represent input/output operations?

• Rectangle

• Diamond

• Parallelogram

• Oval
