This example tokenizes a string using multiple delimiters: semicolon, space, and comma.strtok_streats any sequence of these characters as a single delimiter. The output shows all fruits separated regardless of which delimiter was used. This flexibility makesstrtok_suseful for parsing complex input....
tokenize 的能力很 trivial 这里可以看出,它是无法同时处理两个字符串的,如果一个字符串处理了一半,再使用另一个字符串作为 str 参数的话,内部存储位置的指针会被重新初始化,进而把原先字符串的处理进度丢失掉。可以使用函数 strtok_r 来解决这个问题,它接受一个指针参数,用来保存当前的字符串处理位置。 由于每调用...

词法解析里面唯一的方法 tokenize 这个方法会去读源码的字符 这个方法做分词 分词完了之后 输出它是什么类别、在类别中具体的内容 它的返回值叫token和token value 这个方法的返回值类型是void 通过全局变量来定义token和token value 通过修改全局变量来告诉parser的其他部分 ...
