dijkstra算法源代码，实现了dijkstra算法，并附有一个简单路网文件-dijkstra algorithm source code, to achieve the dijkstra algorithm, together with a simple network file

简单的实现Dijkstra算法求最短路径，能输几个节点及各个节点的距离，然后算出中心节点与其他节点的最短路径。-Simple implementation Dijkstra algorithm seek shortest path, can lose several node and various node distance then calculated center node with other node shortest path.
