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...

strcpy (str1,str);而这个是干什么呢,它将字符串str的内容存入到str1开始的地址中,这是一个不确定的地址,这么做是非常危险的,可能会让系统崩溃!!!对于问题补充部分:1.你的返回值有问题 你需要的是指针数组的首地址 所以要指向指针的指针 2.你的循环没有结束条件 char ** tokenizer (char store...
These functions are very useful, if you want to tokenize a string. C provides these handy utility functions to split our input string into tokens. 如果要标记字符串,这些功能⾮常有⽤。 C提供了这些⽅便的实⽤程序函数,可将我们的输⼊字符串拆分为标记。 Let’s take a look at using ...
