Before read a lot about Uboot analysis, which has said to the C language, ready to run the stack.
And in Uboot's START.S assembly code, for system initialization, you also see a stack pointer that initializes this action. But I've never seen anyone say system initialization to initialize the stack, that is, assign values to the stack pointer sp correctly, but never see anyone explain why the stack is initialized. So, the next thing is, after a certa
Easy Language Introduction:
Easy language is a programming language in Chinese as a program code. Known for its "easy". Founder for Wu Tao. The earlier version of the name is E language. The release of the earliest version of the language can be traced back to September 11,
Easy language is called full visual programming language, because its development interface and the DOS interface of the general programming interface, is graphical, it is the application of graphics, is the future runtime to see the program interface. The entire programming process is visual and can be called "WYSIWYG".
Below, we start the Easy language softwar
How to use C language object-oriented and C language object-oriented
We all know that C ++ is an object-oriented language, but can C use object-oriented functions?
(1) Inheritance
1 typedef struct _parent2 {3 int data_parent;4 }Parent;5 typedef struct _Child6 {7 struct _parent parent;8 int data_child;9 }Child;
When designing C
In general, the programming language can be divided into two categories: the compiled language and the interpreted language.Compiled languagesMany of the traditional programming languages, such as Fortran, Ada, Pascal, C, C + +, and Java, are compiled languages. These languages require that the source code that we have written be converted into a target tag (object codes), and this process is called "compil

[Java] I. Basic understanding
When I heard about the term "Java" for the first time, I always thought that he was so tall and unmeasurable. In this way, his impression has been kept until now ...... Because of the soft test, you have to cultivate your feelings with Java in advance! I know from a preliminary understanding that I can also grow taller.
Looking at the simplest HelloWorld example, we found that the big framework is actually fixed, and the difference is that the call between various c

Tool or Xcode, Android Studio.From the famous IDE IntelliJ idea (Android Studio based on this development) software development company JetBrains (located in Eastern Europe, Czech Republic) originated from JetBrains's team of St. Peters
One of the most important features of. NET is cross-language programming, and DLLs written in C # can be called in vb.net, for example:A class written in C #, compiled into a DLL, and then called in vb.net:Using System;Namespace Clssample{public class Clstest{Public Clstest (){}public void ABC (){Console.WriteLine ("ABC");}}}Called in vb.net:Dim C as Clssample.clstest = New clssample.clstestC.ABC ()Now add a function to the Clstest class in the DLL:pu

One, you can say that it is a compiled type. Because all Java code is to be compiled, Java is not compiled without any use.Two, you can say that it is an explanatory type. Since the Java code cannot be run directly after compiling it, it is interpreted as running on the JVM, so it is interpreted as an explanation.Third, however, the current JVM for efficiency, there are some JIT optimization. It will also compile the. Class binary code to run directly on the local code, so it is compiled again.s
1 What is a C-language implicit function declaration
In the C language, a function does not have to be declared before it is invoked. If there is no declaration, the compiler automatically generates assembly code for the C code of the calling function according to an implicitly-declared rule. Here is an example:
int main (int argc, char** argv)
{
Double x = any_name_function ();
return 0;
}

The Windows operating system is the perfect platform for programmers. There are hundreds of languages for Windows®, some of which are implemented directly through the WIN32®API or the CLR, but more often through your authoring.

1 C Language Program composition Way
1 C Language Program is composed of functions, each function can implement one or more functions.
2 A regular program can have multiple functions, but there is only one main function.
3 The function is executed only when it is called, and the main function is executed by the system call.
4 The format of the function must be written in accordance with the specification.
uniquely identifies each row in the table. Tips:Primary keys should always be defined, although primary keys are not always required, but most database designerswill ensure that each table they create has a primary key for future data manipulationand management. Any column in the table can be a primary key, as long as it meets the following criteria:1) No two rows have the same primary key value2) Each row must have a primary key value (primary key column does not allow null values)3) values i

1The memory occupied by a C-compiled program is divided into the following parts:
1. stack: automatically allocated by the compiler when the program is running, storing the function parameter values and local variable values. The operation method is similar to the stack in the data structure. The compiler Automatically releases the
When can return be omitted during recursion in C language: Interpreting the essence of return in C language functions through inline assemblyThe story goes like this. The blogger uses recursion when writing a simple business in C, and forgets to write return due to carelessness. The returned results are still correct. After 30 minutes of disassembly and debugging, I have proved my conjecture and I am sharin
