My goal is to make a C function that just walks a query string and splits on the ampersand and the equals sign. I am getting stuck on this error from Valgrind. ==5411== Invalid free() / delete / delete[] / realloc() ==5411== at 0x402AC38: free (in /usr/lib/valgrind/vg...

The strncpy() function is similar, except that at most n bytes of src are copied. Warning: If there is no null byte among the first n bytes of src, the string placed in dest will not benull-terminated. strncpy 一般用来替代strcpy的,比strcpy安全一点,即最多从src中copy n个字符到dst中,如...
就是这段代码,一直报错,初看确实看不到什么问题,为此我加了很多打印,最后确定问题就发生在 free(Matchverb);free(Matchnoun);这两句话,下面就讲一个一知识点,为什么free发生异常了呢? 我们在使用malloc分配内存后,指针变量获取到了地址。但是在程序中我们又给指针变量重新赋值了,因此地址发生了变化,此时我再次使用...

虽然，我没怎么看懂你的思路。但感觉问题应该是，你申请结点的时候，没有NULL赋值给没有孩子的结点。如果不是NULL，验证程序就会一直遍历~ 仅供参考。。
