of void main (). In C99, the standard requires the compiler to give at least a warning to the use of main ().(1) in C languageIn C89, main () is acceptable. The classic masterpiece of Brian W. Kernighan and Dennis M. Ritchie, the C programming Language 2e (second edition of the C programming language), is the main (). However, in the latest C99 standard, only the following two definitions are correct:int main (void)int main (int argc, char *argv[])(reference: ISO/

When you are working with Word or Excel, you cannot embed the interop type "..." in VS2010, instead, use the workaround for the applicable interfaceAsked the mother, the solution is the same: Select the DLL that was introduced in the project, right-click, select Properties, set the "Embed interop type" to false. After the problem is solved easily, there should be a lot of people who are struggling with this "embed interop type" What is the meaning of it? Let me slow down the road. (If you don't

expressed using multiple bytes to express a symbol. For example, the common encoding method in Simplified Chinese is GB2312, which uses two bytes to represent a Chinese character, so it is theoretically possible to represent a maximum of 256x256=65536 symbols.The issue of Chinese coding needs to be discussed in this article, which is not covered by this note. It is only pointed out that although a symbol is represented in multiple bytes, the Chinese character coding of the GB class is irrelevan

MPEG-4 Part 2,MPEG-4 visual(Formally ISO/IEC 14496-2[1]) is a video compression technology developed by MPEG. it belongs to the MPEG-4 ISO/IEC standards. it is a discrete cosine transform compression standard, similar to previous standards such as MPEG-1 and MPEG-2. several Popular codecs including DivX, Xvid and Nero digital implement this standard. Note that MPEG-4 Part 10 defines a different format than

applications. This is actually the most fundamental problem. In fact, in any project, the flexibility of applications and the complexity of development are the eternal opposition. To provide the most flexibility, the development complexity is not average. The biggest difficulty is the selection of the development complexity caused by the flexibility required by the application and the extended mechanism provided by the selected workflow engine.

The 39th Technical Committee (TC39) was delegated to "standardize the syntax and semantics of a generic, cross-platform, vendor-neutral scripting language" (http://www.ecma-international.org/memento/TC39.htm). The ECMA-262, made up of programmers from Netscape, Sun, Microsoft, Borland and other companies interested in scripting, defines a new scripting language called ECMAScript.Agile Microsoft, slow NetscapeAlthough Netscape d

This leads to a direct consequence: JScript becomes the de facto standard for JavaScript language.Development of standards:In the next few years, the International Organization for Standardization (ISO/IEC) also adopted ECMAScript as the standard (iso/iec-16262).
