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。
