问题描述

Is there a limit of memory that can be allocated and accessed with Visual C++ 2013 -- 64 bit?

推荐答案

是.该限制因计算机而异，具体取决于可用的虚拟内存量.如果您的程序要求操作系统，操作系统将尽其所能分配一个连续的块.这就是为什么分配内存时总是 如果无法获得内存，则需要进行错误检查.

Yes. That limit will vary from machine to machine depending on how much virtual memory is available. The operating system will do what it can to allocate a contiguous block if your program is asking for it. That's why when allocating your memory you always need to have error checking in case the memory can't be obtained.
