所以才可以用delete[]而不是delete[N]。 同理,使用malloc()时也会在返回的指针之前的某个地址记录申请内存大小,这样free()就会在释放内存时找到这个记录分配大小的地址,然后知道释放多少。 C/C++不会像java一样在编译层面检查下标是否越界,所以如果不在代码里手动检查,下标越界可能会导致库函数需要用到的内存地址被...

LZ 今天在写一个 Socket 程序的时候使用 malloc(3) 在堆上动态分配了一个结构体的空间,在使用完之后用 free(3) 函数释放空间的时候报invalid next size这样的一个错误,经过了两个小时的调试,最后发现是因为粗心越界导致的。 LZ 把这个错误缩减为一个最简单的模型发布出来: 1#include <stdio.h>2#include <st...
