Default value 0Short: 16 bits, 2 bytes, value range-32768~32717, default value 0int: 32 bits, 4 bytes, value range-2147483648~2147483647, default value 0long: 64 bits, which is 8 bytes-2^63~2^63-1, default value 0Lfloat: floating point, 32 bits in memory, 4 bytes, for storing a number with a decimal point (the difference from a double is that the float

There is a section explaining the value types and reference types well. Excerpt from a book, as follows:Before analyzing the value types and reference types in C #, let's say two examples to make the concept of abstraction concrete.Suppose you are reading a book, and your friend wants to see the book in your hand at th

IntroductionThis article mainly introduces. NET 6 Important concepts: stacks, heaps, value types, reference types, boxing, unpacking. This article begins with a description of what happens inside the compiler when you declare a variable, and then introduces two important concepts: stack and heap, and finally introduces value types and reference

. NET Six musketeers: Stacks, heaps, value types, reference types, boxing and unpackingOne. " Heap "," stack "zoneI believe you are too familiar with these two words, even rice is what? I don't know... What is "heap" and "stack"? Oh, this one knows ...Before I also wrote a stack of articles, but not deep in writing, the analysis is not comprehensive, so today also refer to some of Daniel's information.I. Pr

1. Value type (ValueType)Value types include: numeric type, struct, bool, user-defined struct, enum, nullable type.Variables of value types store data directly and are allocated in the managed stack. Variables are automatically released when the method that created them is returned, such as declaring a char-type variable name= ' C ' in a method, and the memory that the name variable occupies on the stack is

NET Technology Foundation supplements achieves the restudying effect, finally also is in order to exercise own English reading and writing ability. Because it is the first time to translate English article (Ah, forgive me this dish than, weak explosion!) , so there will certainly be a lot of problems (some of the sentence understanding is n

Parse the local method to map the data types at the Java layer, and map the data types at the java layer.Preface The Java language defines different data types, such as basic types int and double, and all classes parent class objects. These are Java-level types, the processi

Most of the programming languages that most people learn systematically are the differences between value types and reference types, one of the first points learned in the learning process of these languages. Let's look at the differences between basic data types (Primitive Types) and reference

Java Program Design tutorial is a Chinese-American work, and there is Nicholas C. zakes's JavaScript advanced programming, also has the illustrator C #2008, which is translated into "illustration C #2008". In fact, there are not many illustrations. This is my first complete reading of the original version. First, I can still use English. I want to score more than 20 points after I take the cet6 test ,-!! Second, foreigners write books with their heart. treating their books is just like treating
