Cosc 2425 Project 2 Part 1 Implement The Following C 157786

Cosc 2425 Project 2part 1implement The Following C Code Fragment I

Cosc 2425 Project 2 part 1 requires implementing a C++ code fragment in assembly language using the block structured .IF and .WHILE directives, assuming all variables are 32-bit integers. The code involves iterating over an array to sum elements within a specified range, counting how many elements qualify, and displaying this count along with the final sum. Additionally, the assignment includes developing an assembly program that prompts the user for an integer dollar amount between 1 and 3,000, then outputs a donation class based on the input, repeating until a sentinel value is entered. The program must validate inputs and handle invalid entries with appropriate messages.

Introduction

Assembly language programming offers low-level access to hardware and provides significant control over computer operations. In this project, we undertake the task of translating a specific C++ code fragment into assembly language utilizing structured blocks such as .IF and .WHILE, then extend this understanding to create an interactive program to classify donation amounts. These exercises demonstrate core concepts in assembly programming, including looping, conditional execution, user input validation, and output formatting, which are critical for embedded systems, operating system kernels, and performance-critical applications.

Part 1: Converting C++ Loop to Assembly

The first part involves translating a C++ code snippet into assembly, focusing on maintaining the logic and structure, specifically the use of block directives like .IF and .WHILE. The C++ code initializes an integer array with specific values and defines variables to set lower and upper bounds for inclusion. The goal is to iterate through the array, summing elements within the bounds, counting the number of qualifying elements, and displaying these metrics. The variables involved are all 32-bit integers, making them suitable for standard assembly register operations.

Implementation Details

• Variables: array, lower, upper, ArraySize, index, sum, and count
• Operations: iterate over the array while index
• Condition: if array[index] >= lower AND array[index]
• Actions: accumulate sum, increment count
• Output: total qualified count and final sum

Utilizing a simplified assembly syntax with directive support for structured control statements, the program starts by establishing data section variables, then proceeds to initialize registers for iteration. Loop constructs emulate the C++ while loop, with nested if statements for condition checks, updating counters accordingly. After the loop terminates, the program calls predefined procedures to display results.

Part 2: User Input and Classification Program

The second part centers on creating an assembly program that interacts with the user to input a dollar amount between 1 and 3000. Valid inputs are classified into donation categories based on predefined ranges: Platinum, Gold, Silver, Bronze, and Copper. The program performs input validation, providing appropriate messages for invalid entries. The loop continues until a designated sentinel value triggers termination, which can be defined as entering a specific number outside the valid range or zero.

Implementation Details

• Prompt the user for an input amount.
• Validate that the input falls within 1–3000; otherwise, display an error message.
• Check if the input matches the sentinel value, and break the loop if so.
• Classify the amount based on the table and display the class description.
• Repeat the process until the sentinel is detected.

This program exemplifies control flow mechanics, user input validation, conditional branching, and output formatting in assembly language, emphasizing robustness for user interaction scenarios.

Conclusion

This comprehensive approach demonstrates the translation of high-level control structures into assembly language and the development of user-interactive programs. Through meticulous implementation of structured directives and validation mechanisms, these exercises deepen understanding of low-level programming paradigms essential for system-level development.
