利用Hash技术统计C源程序中关键字的频度：扫描一个C源程序，用Hash表存储该程序中出现的关键字，并统计该程序中的关键字出现的度。用线性探测法解决Hash冲突。设Hash函数为：Hash(Key)=[(Key的首字母序号)*100+(Key的尾字母序号)] Mod 41。关键字39个。-Hash statistics using C source code in the frequency of keywords: Scanning a C source program, using Hash Table to store the keywords appear in the procedure, and statistics keywords in the program appears degrees. Linear detection method to resolve the conflict Hash. Based Hash function: Hash (Key) = [(Key the first letter of the serial number)* 100+ (Key serial number of the end of the letter)] Mod 41. Keyword 39.
