I encountered a small computation during the C ++ review. I still have a lot of knowledge. Let's start with your attention! Char * str1 = "absde"; char str2 [] = "absde"; char str3 [8] = {'A' ,}; char ss [] = "0123456789 "; why sizeof (str1) = 4

Brief introduction:both string and StringBuffer can store and manipulate strings, which are string data that contains multiple characters. Their difference is that the string class is a constant of strings and is immutable. While StringBuffer is a

Use VBox to simulate storage migration environments, os:rhel5.9,db:oracle 10.2.0.4 RAC ASM 2Nodes. ASM uses extern redundancy, which does not use ASM's rebalance functionality, and OCR and Votedisk are stored in raw. Migration includes Controlfile,

In this article, we discuss a question: How to calculate (or, estimate) the amount of memory that a Java object occupies?In general, we are talking about the premise that heap memory is used in a "general" context. The following two scenarios are

The use of the sizeof () function in C + +Learning C + + sometimes encounters the following scenario:Known char *str1= "ABSDE";Char str2[]= "ABSDE";Char str3[8]={' a '};Char STR4 [] = "0123456789";Why sizeof (STR1) =4sizeof (STR2) = 6;sizeof (STR3) =

The example in this article describes how to calculate (or estimate) the amount of memory a Java object occupies. Share to everyone for your reference. The specific analysis is as follows: In general, the premise of the heap memory usage we are
