键盘 转换 哈哈 很好用的 但是可能会有些小问题但是问题不大 可以用(Conversion ha ha very good keyboard but may be used for small problems but can not be a big problem)

编写C程序，随机给出n*n的邻接矩阵，并打印输出邻接矩阵，以及有向图的边的个数，每个顶点的度，并判断该图中是否存在Euler回路： （1）如果为n阶，则随机产生一个n*n的邻接矩阵； （2）输出邻接矩阵，边的个数，每个顶点的度以及图中是否存在Euler回路。 这个题目涉及到了两个主要的知识点，一个是数据结构中的有向图的邻接矩阵的创建，还有就是离散数学中的Euler回路的判定定理。(The preparation of C procedures, were randomly given n* n s adjacency matrix and adjacency matrix printouts, as well as to map the number of edges, each vertex degrees, and determine the existence of the map Euler circuit: (1) If for n-order, then randomly generated a n* n adjacency matrix (2) output adjacency matrix, the number of edges, each vertex of degree as well as map the existence of Euler circuit. This topic relates to two main points of knowledge, a data structure of digraph adjacency matrix of creation, there is discrete mathematics in the loop to determine Euler theorem.)

这是简单的最优潮流程序，经过IEEE4、IEEE14、IEEE30、IEEE118、IEEE1047系统测试的。(It is a simple optimal power flow program, after IEEE4, IEEE14, IEEE30, IEEE118, IEEE1047 system testing.)
