Strtok()函数详解：

  该函数包含在"string.h"头文件中 
函数原型：

1. char* strtok (char* str,constchar* delimiters );

函数功能： 
  切割字符串，将str切分成一个个子串 
函数参数： 
  str：在第一次被调用的时间str是传入需要被切割字符串的首地址；在后面调用的时间传入NULL。 
  delimiters：表示切割字符串（字符串中每个字符都会 当作分割符）。 
函数返回值： 
  当s中的字符查找到末尾时，返回NULL; 
  如果查不到delimiter所标示的字符，则返回当前strtok的字符串的指针。
