Use of LCC-Win32!
About LCC-Win32LCC-Win32 is a free open source Win32 compiler, contains a very useful IDE,It is easy to use, but the source code has recently started to pay (40 US dollars ). For more information, see the LCC-Win32 official website.Its free version can be obtained in China. You can go to the Yunfeng studio to see what you will get.Direc
One of the most important features in LCC is the ability to output different target codes. For example, the same C program, can generate MIPS, X86 and other assembly code, only need to choose a different target parameters. Only the code that generates X86 is parsed here, so the parameters of the command line are as follows: Rcc.exe-target=x86/nasm hello.i hello.asm parameter-target=x86/nasm is the X86 assembler code that lets the C compiler choose to
Tag:oat need iloefiict put using eccwgs84 Proj4 is a very useful coordinate system conversion library, its rich coordinate system type and development language, make the conversion very convenient, but when we only need the very few coordinate systems to convert each other, the coordinate volume is relatively large, it is faced with performance problems, in view of the use of work, the extraction of the LCC and WGS84 coordinate system transformation
The Do-while statement is a loop structure that implements the "until type". The general form is as follows: do { Statement 1}while (expression) The above statement is executed, EXECUTE statement 1 First, then determine the value of the expression, if the value of the expression is true, that is nonzero, return to execute statement 1, so repeatedly, until the value of the expression and so on Until 0. The difference between this expression and the previous while statement is the judgment of the
LCC uses a large chunk of memory, it is also very special allocation of memory, its source program is as follows: #001 //large memory structure. #002 struct block #003 {#004 struct block *next;//successor block pointer. #005 Char *limit; Tail position #006 char *avail; The available start position. #007 }; #008 #009 //share the largest type. #010 union align #011 {#012 long l; #013 char *p; #014 Double D; #015 Int (*f) (void); #016 }; #017 #

In SQL Server 2005, the cross apply and outer apply join statements are added. What is the role of adding these two statements?
We know that one SQL Server 2000 has a cross join used for cross join. In fact, adding cross apply and outer apply is used to cross join the table value function (the function that returns the
In SQL Server database operations, a new apply table operator has been added for more than 2005 versions. The new apply table operator applies the right-table expression to each row in the left-hand table expression. It is not possible to calculate the table expression first as join, and apply must logically evaluate the left expression first. The logical order o
The apply and call functions are the same, but the input parameter lists are in different forms. This article introduces the definitions of the apply and call methods and the differences between the apply and call methods, if you are interested in learning it together, if you haven't touched any dynamic language, it will be amazing and strange to understand javaS

First, let's look at the call explanation in MDN.
The call () method calls a function or method when a specified this value and several specified parameter values are used.
Note: The function of this method is similar to that of the apply () method. The only difference is that the call
When you encounter multiple table queries in your daily development, you will first think of INNER join or left OUTER join, and so on, but these two queries sometimes do not meet the requirements. For example, when a left table is associated with multiple records in the right table, I need to control one or more records in the right table to match the left table. It seems that the INNER join or the left OUTER join is not well done. But cross apply and
If you haven't contacted a dynamic language, it will be a magical and weird feeling to understand JavaScript in a compiled language, because the things that are often impossible in consciousness happen, and even feel unreasonable. If you're learning JavaScript in a free and changing language, this is the way you feel. , then from the beginning, please put down your "prejudice", because this is absolutely a new continent for you. Well, not to everyone chit chat when, to get to the bottom of it, l

What are the differences between the apply () and call () methods in javascript?
Call and apply all belong to Function. A prototype method is implemented internally by the JavaScript engine because it belongs to the Function. prototype, so each Functi
In SQL Server database operations, a new application table operator is added to the version above 2005. The new apply table operator applies the right table expression to each row in the left table expression. It does not compute that table expression as a join, and the apply must first compute the left expression logically. The logical order of this calculation input allows the right expression to be assoc
