添加到内存地址错误 [英] Adding to a Memory Address Error

问题描述

这不会在VSC ++ 2008中编译。

  void * toSendMemory2 = toSendMemory + 4; 
  

我为什么不知道，虽然我确信这很蠢。 ：P $ <$>

$ <$> c> T * 指针将增加 sizeof（T）* N 字节。 sizeof（void）是无意义的，因此不允许对 void * 进行指针运算。

This doesn't compile in VSC++ 2008.

void* toSendMemory2 = toSendMemory + 4;

I am at a loss at why, though I am sure it's very stupid of me. :P

解决方案

When you add N to a T* the pointer will be incremented by sizeof(T) * N bytes. sizeof(void) is nonsensical, so pointer arithmetic over void* is not allowed.
