摘　　要：为了提升大学生对C语言语法原理的理解,通过对比C语言语句与汇编指令,提出了一种在程序调试时使用汇编指令去理解分析C语言语法原理的方案。首先对C语言可执行程序的运行原理进行了介绍,然后介绍了JFE and GCC软件的调试功能,再然后区分了AT&T与Intel汇编指令的不同之处,最后就一个程序调试的实例进行了汇编指令分析。实验关于赋值语句的机器指令分析,验证了C语言在编译时确定局部变量的地址空间,实验体现了汇编指令分析有效、实用。In order to improve the college students'understanding of C language grammar principle,by comparing C language state⁃ments with assembly instructions,a scheme of using assembly instructions to understand and analyze C language grammar princi⁃ple in program debugging is proposed.Firstly,the operation principle of C executable program is introduced;then,the debugging functions of JFE and GCC software are introduced,and then the differences between AT&T and Intel assembly instructions are distinguished,finally,the assembly instructions of a program debugging example are analyzed.By analyzing the machine instruc⁃tions of assignment statements,it is verified that C language determines the address space of local variables at compile time,the experiment shows that the assembly instruction analysis is effective and practical.
