How to allocate variable-size arrays on the Stack in C/C++ Introduction C language provides the alloca function to allocate arbitrary size array on the stack. After the function returns or the scope ends, the stack memory is automatically reclaimed back (popped back) without the developer having...

CWin32Heap::Allocate 从堆对象分配内存块。 virtual void* Allocate( size_t nBytes ) throw( ); 参数 nBytes 请求的字节数在新的内存块。 返回值 返回指向新分配的内存块。 备注 调用CWin32Heap::Free或CWin32Heap::Reallocate释放此方法分配的内存。
C++ 標準一律要求 n 必須等於作為第一個引數傳遞至 allocate 引動過程的值,其會傳回 p。 不過,在目前版本中,會檢查 n 的值。 傳遞 n 之引數和此標準要求不同的程式碼,可能會在執行階段損毀。 hash_map 和 hash_set 非標準的標頭檔 <hash_map> 和<hash_set> 在Visual Studio 2015 中已淘汰,並將於...
