c语言实现最小生成树算法.pdfVIP

最小生成树算法 C语言代码如下： #includestdio.h #includewindows.h #define TURE 999 typedef struct ArcNode { char vexs[10]; int edgs[10][10]; int n,e; }MGraph; struct edg{ int v1; int v2; int cost; }A[10],B[10]; //创建图 void GreateMGraph(MGraph *G) { int i,j,k,weight,m,n; int ch1,ch2; char a,b; printf(请输入顶点数和边数(格式如4):); scanf(%d %d,(G-n),(G-e)); //输入顶点数,边数 for(i 0;iG-n;i++) { getchar(); printf(请输入第%d个顶点:,i+1); scanf(%c,(G-vexs[i])); //输入¨顶点 } for(i 0;iG-n;i++) for(j 0;jG-n;j++) G-edgs[i][j] 0; for(k 0;kG-e;k++) { printf(请输入第%d条边的顶点权值(格式如¨i j):,k+1); getchar(); scanf(%c %c %d,a,b,weight); m 0;n 0; for(m 0;G-vexs[m]! a;m++); for(n 0;G-vexs[n]!b;n++); ch1 m;ch2 n; G-edgs[ch1][ch2] weight;G-edgs[ch2][ch1] weight; } } void prim(MGraph *G, int v) { int i,j,k,min; struct { int adjvex; int lowcost; } closedge[10]; for (i 0;iG-n;i++) { closedge[i].lowcost G-edgs[v][i]; closedge[i].adjvex v; } closedge[v].lowcost TURE; for (i 1;iG-n;i++) { min 100; for(j 0;jG-n;j++) if (closedge[j].lowcost!
