大连理工大学计算机原理实验实验报告三

1、计算机原理实验报告汇编语言编程部分精选范本，供参考!实验（3）名称：计算学生平均成绩实验一、实验目的：1、熟练掌握运算类指令以及其对各状态标志位的影响。2、掌握运算类程序的设计及调试方法。3、掌握BC画的基本知识和BC四的转换。二、实验要求：在DO新境下利用EDIT软件来编辑源文件，并使用MASMLINKT具对源文件进行编译链接，最终在实现对30个学生成绩的求和以及求平土匀数,并将平均数转换为BC明显示出来。三、程序流程图:调累加和子程序调求平均值子程序调转换子程序调显示子程序返回DOS图一求平均分流程图四、程序清单：datasegmentbufdw60,70,80,90,95,98,20,3
