Lab 08 Cusing The Flowchart For Lab 08 As A Guide Write a C Prog

Using the flowchart for Lab #08 as a guide, write a C++ program that determines the student's quiz score based on their responses compared to correct answers. Your program should include two functions: void inputAnswers(char given[]) for accepting user responses, and int numRight(const char correctAnswers[], const char given[]) to calculate how many answers are correct. Remember, Raptor arrays start at 1, but C++ arrays start at 0. Test your program thoroughly before submission, and note that you need to output only the C++ code for this assignment.

This paper discusses the implementation of a quiz grading program in C++, based on a provided flowchart. The core functionality involves capturing a student’s responses to 10 multiple-choice questions, comparing them with a set of correct answers, and calculating the number of correct responses to determine an overall score expressed as a percentage. The program is designed to be modular, utilizing two main functions: inputAnswers to gather user responses, and numRight to compute the number of correct responses. The primary objectives include accurately capturing input, efficiently processing the data, and providing a clear output of performance. Additionally, the program should be easy to test, debug, and verify for accuracy before final submission.

In designing this program, attention must be paid to differences in array indexing conventions between Raptor (starting at 1) and C++ (starting at 0). As such, the array indexing in C++ must be carefully managed to avoid off-by-one errors. The inputAnswers function takes an array of characters where it stores the user’s responses, prompting them question by question. The numRight function receives arrays of correct answers and student responses and iterates through to count the number of matches, returning an integer value representing the total correct responses.

The overall approach involves initializing the array of correct answers within main or as a constant, invoking inputAnswers to collect responses, then calling numRight to compute the score. The final output displays the percentage score based on the number of correct answers out of 10. Additional features, such as identifying which questions were answered incorrectly, could be incorporated, especially for extra credit, but are optional per instructions. Testing involves entering various combinations of responses to ensure accuracy of scoring across different scenarios.

In conclusion, this programming task emphasizes understanding of array manipulation, function implementation, and comparison-based processing in C++. It reinforces concepts of modular programming and careful handling of array indices — essential skills for developing reliable, maintainable code in educational and real-world applications.
