常用的編程語言。
編程語言一：C語言
C語言是世界上最流行、使用最廣泛的高級(jí)程序設(shè)計(jì)語言之一。在操作系統(tǒng)和系統(tǒng)使用程序以及需要對(duì)硬件進(jìn)行操作的場(chǎng)合，用C語言明顯優(yōu)于其它高級(jí)語言，許多大型應(yīng)用軟件都是用C語言編寫的。
編程語言二:java
Java是一種可以撰寫跨平臺(tái)應(yīng)用軟件的面向?qū)ο蟮某绦蛟O(shè)計(jì)語言，是由Sun Microsystems公司于1995年5月推出的Java程序設(shè)計(jì)語言和Java平臺(tái)（即JavaSE, JavaEE, JavaME）的總稱。
編程語言三:c++
C++這個(gè)詞在中國大陸的程序員圈子中通常被讀做“C加加”，而西方的程序員通常讀做“C plus plus" , "CPP”。 它是一種使用非常廣泛的計(jì)算機(jī)編程語言。C++是一種靜態(tài)數(shù)據(jù)類型檢查的、支持多重編程范式的通用程序設(shè)計(jì)語言。
你好，代碼如下：
package?com.test;
public?class?Test?{
public?static?void?main(String[]?args)?{
int[]?daysArg?=?{31,28,31,30,31,30,31,31,30,31,30,31};
for(int?i=0;idaysArg.length;i++){
System.out.println((i+1)?+?"月有"?+?daysArg[i]?+?"天");
}

數(shù)據(jù)庫是按照數(shù)據(jù)結(jié)構(gòu)來組織、存儲(chǔ)和管理數(shù)據(jù)的倉庫，數(shù)據(jù)管理不再僅僅是存儲(chǔ)和管理數(shù)據(jù)，而轉(zhuǎn)變成用戶所需要的各種數(shù)據(jù)管理的方式。數(shù)據(jù)庫有很多種類型，從最簡單的存儲(chǔ)有各種數(shù)據(jù)的表格到能夠進(jìn)行海量數(shù)據(jù)存儲(chǔ)的大型數(shù)據(jù)庫系統(tǒng)都在各個(gè)方面得到了廣泛的應(yīng)用。在信息化社會(huì)，充分有效地管理和利用各類信息資源，是進(jìn)行科學(xué)研究和決策管理的前提條件。數(shù)據(jù)庫技術(shù)是管理信息系統(tǒng)、辦公自動(dòng)化系統(tǒng)、決策支持系統(tǒng)等各類信息系統(tǒng)的核心部分，是進(jìn)行科學(xué)研究和決策管理的重要技術(shù)手段。數(shù)據(jù)庫是一個(gè)單位或是一個(gè)應(yīng)用領(lǐng)域的通用數(shù)據(jù)處理系統(tǒng)，它存儲(chǔ)的是屬于企業(yè)和事業(yè)部門、團(tuán)體和個(gè)人的有關(guān)數(shù)據(jù)的集合。數(shù)據(jù)庫中的數(shù)據(jù)是從全局觀點(diǎn)出發(fā)建立的，按一定的數(shù)據(jù)模型進(jìn)行組織、描述和存儲(chǔ)。其結(jié)構(gòu)基于數(shù)據(jù)間的自然聯(lián)系，從而可提供一切必要的存取路徑，且數(shù)據(jù)不再針對(duì)某一應(yīng)用，而是面向全組織，具有整體的結(jié)構(gòu)化特征。數(shù)據(jù)庫中的數(shù)據(jù)是為眾多用戶所共享其信息而建立的，已經(jīng)擺脫了具體程序的限制和制約。不同的用戶可以按各自的用法使用數(shù)據(jù)庫中的數(shù)據(jù);多個(gè)用戶可以同時(shí)共享數(shù)據(jù)庫中的數(shù)據(jù)資源，即不同的用戶可以同時(shí)存取數(shù)據(jù)庫中的同一個(gè)數(shù)據(jù)。數(shù)據(jù)共享性不僅滿足了各用戶對(duì)信息內(nèi)容的要求，同時(shí)也滿足了各用戶之間信息通信的要求。
