The Tiobe programming language community released the July 2017 rankings, and the rankings were less than June, and Java, C, C + + and Python remained stable in the top 4. The go language soared this year, finally entered the top 10 this month, but only 55 in the same period in 2016, the speed is strong enough, the reason may be related to the development trend of large data ai. Last month, Google announced its full support for Android development and Kotlin,kotlin first 50 last month. This mon

Tiobe published the November 2011 programming language Rankings, the top 20 rankings have not changed much. From the chart below, you can see that the C camp is still the world. It is only two months since Tiobe released the 2011 Annual programming language, which was awarded to the highest-rated programming language of the year (delta in Figure 1). Compared to C # (ordinary youth?) +1.61% and JavaScript (literary youth?) +0.90%, seemingly 2B youth objective-c will be the best candidate for the

In Tiobe's October 2011 programming language Rankings, Java continued to gain momentum in September, declining by almost 1%, despite Oracle's latest Java 7 release in early August. It seems that the C language is returning to its first throne next month. Other notable object-c and Transact-SQL were also highly innovative, reaching 6.245% and 0.909%, respectively. Assembly returned to TOP20, squeezing into the D language of the top 20 last month, Visual Basic. NET rose from 39 to 25, while F #,

August 4, Tiobe released the latest August programming language rankings, compared with the July list, the biggest change in the number of Microsoft F #, F # for the first time into TOP20. From 1 to 10, PHP returns to 4,c# 5th, the other unchanged. The following contents are translated according to the original tiobe: Eventually, a new functional programming language went into top 20. Most people would think popular functional programming

o'clock, then it does not have to be reduced, which is the usage in our macro definition.The CONTAINER_OF macro is also a similar idea, since the current List_node member's offset is found, then minus the offset, is the outer enclosing structure of the start address.Well, so that we can achieve this list, but actually do not bother, there is a simple way, that is to let our list_node member structure, in our data storage structure of the first positi

for text processing and is widely used in many scenarios, including system management, Web development, network programming, and even GUI development. It is easy to use and supports both process-oriented and object-oriented programming. Perl is modular and easy to call third-party modules. Although designed with the goal of a complete Turing programming language, Perl has been used as a system management script since its launch in 1993. Perl supports both compilation and interpretation, so Perl
