连通分量是什么意思
无向图G的极大连通子图称为G的连通分量( Connected Component)。任何连通图的连通分量只有一个，即是其自身，非连通的无向图有多个连通分量。
作为遍历图的应用举例，下面我们来讨论如何求图的连通分量。无向图中的极大连通子图称为连通分量。求图的连通分量的目的，是为了确定从图中的一个顶点是否能到达图中的另一个顶点，也就是说，图中任意两个顶点之间是否有路径可达。这个问题从图上可以直观地看出答案，然而，一旦把图存入计算机中，答案就不大清楚了。
无向图的连通分量
无向图的G的极大连通子图称为G的连通分量（Connected）。任何连通图的连通分量都只有一个，即使是其本身，非连通的无向图有多个连通分量。
使用广度优先搜索或深度优先搜索来计算线性时间内图的连通分量（以图的顶点和边的数量表示）是很直接的。无论哪种情况，从某个特定顶点v开始的搜索将在返回之前找到包含v（并且不再有）的整个连接组件。
要查找图的所有连通分量，循环遍历其顶点，每当循环到达一个尚未包含在先前找到的连通分量中的顶点时，开始新的宽度第一次或深度第一次搜索。

“源代码”是什么意思
源代码是指原始代码，可以是任何语言代码。源码就是指编写的最原始程序的代码。运行的软件是要经过编写的，程序员编写程序的过程中需要他们的“语言”。
计算机里面运行的所有东西都是用程序编出来的(包括操作系统,如Windows,还有Word等,网络游戏也一样),而编写程序要用到计算机语言,用计算机语言直接编出来的程序就叫源码,比如VisualBasic编写的源码文件一般为.bas文件，而用C++编写的一般为.cpp文件，源代码不能直接运行，必须编译后才能运行。源码经过编译处理后就可以直接在操作系统下运行了。-是什么意思
2.很多的站长都喜欢使用建网站的程序源码，因为可以很方便的修改，对于任何一个seo人员来说，都是非常好的一个切入点。
3.从字面意义上来讲,源文件是指一个文件,指源代码的集合.源代码则是一组具有特定意义的可以实现特定功能的字符(程序开发代码)。
4.“源代码”在大多数时候等于“源文件”。
