汇编大作业设计报告班级：JS001005学号：2010300128姓名：王永威一、程序题目及功能1. 题目：基于MASM集成环境的计算器2. 程序功能：本程序实现了两个无符号字节类型的十进制的加法(ADDITION)、减法(SUBTRACTION)、乘法(MULTIPLICATION)、除法(DIVISION)、乘方(POWER OF (X,N) 和阶乘运算(FACTORIAL OF N).二、程序设计要求1. 程序设计要求 1 综合使用32位指令、伪指令、宏指令、子程序等知识 2 开发程序的总代码行数不应少于300行 3 提交作业的内容： 源代码和简要设计报告；编译生成的二进制程序以及关于程序生成方法的说明。2. 作业完成度： 本程序是在 MASM for Windows（32位系统，兼容XP）集成开发环境下开发的，综合使用了32位指令、伪指令、宏指令（如程序的宏定义DISP）以及递归设计，每一个计算功能模块都采用子程序以实现。开发程序总代码为438行，源代码、编译生成的二进制程序以及程序成方法见后文，并通过多次实验验证了程序的正确性。三、程序设计流程1. 具体流程图（如图1所示）2. 程序各模块分析 1 主程序模块分析 本模块中设计了菜单选项，通过y 或n可以选择继续还是退出操作。如果继续，则会给出子菜单选项，对应了a-f 7 个运算功能，选择其中一个后，会根据子函数相应功能提示用户进行一个或两个输入数据。输入后屏幕即可显示运行结果。 在主函数中使用了宏定义：DISP MACRO M，功能是便于字符串的显示。除此之外，主函数可以调用数据输入、输出以及其他各个子函数。2 一般运算函数分析加法、减法、乘法、除法和乘方都是通过子函数的参数传递、特定函数的运算和输出打印来实现的。3 递归函数分析在功能f中，通过建立堆栈的方法实现递归调用。 菜单 转入相关函数执行N退出吗？ 选择a-fY退出图1 程序流程3. 程序正确性验证 1 程序开发环境 Masm for Windows 集成环境共享版 2 程序运行方法介绍 一步步按照下面图示的演示即可实现程序完整的功能： 附源程序：;THIS IS A COMPLIING PROGRAM;IT IS TO CALCULATE ADDITION,SUBTRACTION;MULTIPLICATION,DIVISION;POWER OF (X,N) AND FACTORIAL OF NUMBER NDATA SEGMENTSTR1 DB 0AH,0DH, * *$STR2 DB 0AH,0DH, * *$STR3 DB 0AH,0DH, * WELCOME TO OUR CALCULATOR!
