如sizeof(max)若此时变量max定义为int max(),sizeof(char_v) 若此时char_v定义为char char_v [MAX]且MAX未知,sizeof(void)都不是正确形式。 三、sizeof的结果 sizeof操作符的结果类型是size_t,它在头文件中typedef为unsigned int类型。该类型保证能容纳实现所建立的最大对象的字节大小。 1、若操作数具有...
final int size = (int)Math.round( (heap2 - heap1)/(double)count ); System.out.println("heap1 = " + heap1 + "; heap2 = " + heap2); System.out.println("heap2-heap1 = " + (heap2 - heap1) + "; " + objs[0].getClass().getSimpleName() + " size = " + size); for...
I am migrating C++ 32 bit application to 64 bit. In this to convert size_t to int I am just type casting like thisint nInLen = (int) strlen( lpstrAddrIn );Is it safe or should I declare nInLen as size_t?Please suggest anyone your ideas.Thanks....
这个例子也说明了这个错误很稀少 – 为了看到 VM 达到数组大小的限制, 你需要分配一个数据刚好位于平台的限制和Integer.MAX_INT之间. 当这个例子在 64bit Mac OS X, Hotspot 7 上运行时, 只有 2 个满足要求的数组长度:Integer.MAX_INT-1andInteger.MAX_INT. 7.4 解决方案 java.lang.OutOfMemoryError: Reques...

从上面可以看到在出现两次 java.lang.OutOfMemoryError: Requested array size exceeds VM limit之前,出现了更熟悉的java.lang.OutOfMemoryError: Java heap space。这是因为您试图为2^31-1 int原语腾出空间需要8G内存,这比JVM使用的默认内存要少。 解决方案 java.lang.OutOfMemoryError: Requested array size exc...
