C语言和汇编语言的互调.doc

实 验 报 告课程名称： C语言和汇编语言的互调 姓名学号组员实验名称C语言和汇编语言的互调实验内容：(实验原理、实验步骤、数据处理、误差分析、程序算法、系统结构等)一 实验原理C语言参数传递原则 1、函数的返回值通过AX寄存器； 2、参数通过堆栈传递：参数传递的顺序是最后一个参数先入栈，第一个参数最后入栈； 3、在子程序中不对因传递参数而改变的SP进行校正，而在主程序中进行校正。 二 实验步骤1、下载TC.RAR到D盘，解压到D:TC目录中；2、把MASM.EXE拷贝到D:TC中；3、在D:TC目录中建立两个文件DtoA.c和T3.asm，分别存放本题的C语言程序和汇编语言程序；4、执行如下命令，编译T3.asm，形成目标文件T3.obj msam T3.asm5、执行如下命令，编译DtoA.c形成DtoA.obj文件，并把DtoA.obj和T3.obj链接，形成可执行文件DtoA.exe tcc DtoA.c T3.obj6、执行T3.exe。三 流程图四 程序C语言程序#include extern int CHANGE(int,char *);main() int a5=276,13965,1024,4,32,i,j; char
