Scenario-Based Questions

Object-Oriented Programming

Read each real-life situation carefully and apply the correct programming concept to solve it.

✅

Section 1

Application-Based Questions

Apply · Solve · Change · Relate · Complete · Use

1.Apply the steps of program execution to explain how a student should run a newly written C++ program in a computer lab.

2.Apply the use of cout and cin in a scenario where a program must take a user's age and display a personalized message.

3.Solve a situation where a student forgets to declare a variable before using cin and the program gives an error.

4.Solve a problem where a loop prints numbers infinitely because the update statement is missing.

5.Change a program that prints 1 to 100 using 100 cout statements into a loop-based solution.

6.Change a decision-making program using multiple if statements into a switch statement for a menu-driven system.

7.Relate the concept of implicit type conversion to a scenario where an int and double value are used together in a banking calculation.

8.Relate the need for comments in a team project where multiple programmers are working on the same C++ code.

9.Complete a grading system program by selecting the appropriate decision statement when marks fall into multiple ranges.

10.Use the setw manipulator to format student marks in aligned columns for a school report system.

Section 2

Analysis-Based Questions

Analyze · Contrast · Connect · Take Apart

1.Analyze how proper program structure improves debugging and future modification in a large C++ project.

2.Analyze why selecting the correct data type (int, float, char, bool) affects memory usage and accuracy in a payroll system.

3.Analyze how implicit and explicit type conversion affect the result of a mathematical calculation program.

4.Analyze the role of loops in reducing repetitive code in a program that processes 100 employee records.

5.Contrast the working of for and while loops when the number of repetitions is known versus unknown.

6.Contrast entry-controlled and exit-controlled loops in a menu-driven banking application.

7.Connect relational and logical operators in a scenario that checks if a person is eligible to vote and has a valid ID.

8.Connect library functions and header files in a program using mathematical calculations and string operations.

9.Take apart the structure of a simple C++ program and identify the purpose of header files, namespace, main function, and return statement.

10.Take apart a function into its declaration, definition, and call in a calculator program that adds two numbers.

Evaluation-Based Questions

Evaluate · Judge · Value · Grade

1.Evaluate the effectiveness of using loops instead of repeated statements in a large data-processing program.

2.Evaluate whether using switch is more suitable than if-else in a fixed menu-based system.

3.Evaluate the importance of explicit type casting in financial applications where decimal values must be controlled.

4.Evaluate the usefulness of library functions in reducing development time in a student project.

5.Judge whether a while loop is appropriate for input validation in a login system.

6.Judge the risk of infinite loops in a real-time system and how they affect program performance.

7.Value the importance of comments in maintaining readability of a complex C++ program.

8.Value the role of correct data type selection in improving program efficiency and accuracy.

9.Grade the suitability of structures in organizing student records in a college database system.

10.Grade the importance of functions in improving modularity and reusability in a large-scale C++ application.
