First, what is memory alignment and why is memory alignment required?The memory space in modern computers is divided by Byte, in theory it seems that access to any type of variable can start from any address, but the reality is that when accessing a particular type of variable, it is often accessed at a specific memory address, which requires all types of data to be spatially arranged according to certain r

Memory space allocation and byte alignment of struct, and byte alignment of structure AllocationMemory alignmentI:1. What is memory alignment?Suppose we declare two variables at the same time:Char;Short B;Use the (take the address symbol) to observe variable,B address, we will find (taking 16-bit CPU as an example ):If the address of a is 0x0000, the address of

One, data alignment/memory alignmentWord, double word, four words do not need to be aligned in memory on natural boundaries. (What is called a word?) See part II)For the word, double word, four words, the natural boundary is even address, can be divisible by 4 address, can be divisible by 8 address.In any case, in order to improve the performance of the program, data structures (especially stacks) should be aligned as far as possible on natural bounda

About code alignment and about code alignment Click "ZTE developer community" at the top to follow us Read an original article by a front-line developer every day 1. Why code alignment? Programmers do not just write programs, but programs are just a way to implement business. However, it is not that easy to make the way to implement the business more artistic.

Structure boundary alignment and structure boundary alignment The structure boundary is a conventional topic. There are many explanations on the Internet, but most of them focus on the steps. The reasons for each step are a bit unclear, the following describes the structure Alignment Based on the online explanation and your understanding, which is not necessarily

TextView is a basic Android control. It is indispensable for text. However, in the recent project development process, I found that TextView has many limitations. The most headache is the TextView text layout problem. We all know that the text Alignment Methods in word are left, right, center, and scattered alignment, but TextView does not have the attribute setting of scattered

Memory alignment and memory alignment principles # Pragma pack (8) Struct TestStruct4 { Char; Long B; };Struct TestStruct5 { Char c; TestStruct4 d; Long e; }; # Pragma pack () Question: A), sizeof (TestStruct5) =? B) How many bytes are left behind c in TestStruct5, followed by d? In TestStruct4, member a is 1 byte, which is aligned by 1 byte by default. The alignment
