用C语言实现数据结构中的图的建立和输出，可实现输出有向图和无向图，由用户自己选择建立有向图还是无向图的邻接矩阵。用户输入图的定点和边的信息，存储到相应的存储结构中去，而后输出图的邻接矩阵。-Data structure using C language implementation of the map creation and output, enabling the output have to map and undirected graph, chosen by the user to establish a directed graph or undirected graph of adjacency matrix. The user to enter the fixed-point and edge map information stored in the corresponding storage structure go, then the output graph adjacency matrix.
