Little C解释程序源代码用C语言实现了一个C语言的子集的解释程序，之所以是子集，是由于考虑到本次毕业设计的时间上并不允许将整个C语言的解释程序完成，事实上，若要将整个C语言的解释程序完成，那将不是凭一己之力加上数月可以完成的。为此，结合所学的编译原理和实现技术以及计算理论，本文之实现了C语言自己的解释程序。-C source code using C language of a C language subset of the procedures explained that the reason is the subset is due to the graduation of design time and would not allow the entire C language to explain procedures are completed, in fact, if the entire C language to explain procedures completed, it will not be through their own efforts with a few months to complete. To this end, learning by combining theory and compiler technology and computing theory, the realization of the C language interpreter.
