求大神解决

AdjMGraph g;
char a[] = {'A','B','C','D','E','F','G','H'};
RowColWeight rcw[] = {{0,2,5},{0,3,30},{1,0,2},{1,4,8},{2,1,15},{2,5,7},{4,3,4},{5,7,8},{4,7,9},{5,8,9}};
int i,n = 8,e=10;
int distance[6],path[8];
CreatGraph(&g,a,n,rcw,e);


SeqStack myStack;
StackInitiate(&myStack);
char Orig,model;
int idex,idex1;
int j;
printf("\n请输入出发点和终点(A--H):");
scanf("%c %c",&Orig,&model);
for(i=0;i<8;i++)
{
if(a[i]==Orig)
{
idex=i;
break;
}
}
Dijkstra(g,idex,distance,path);
printf("%c点到%c的路径为:\n",Orig,model);
for(i=0;i<8;i++)
{
if(a[i]==model)
{
idex1=i;
break;
}
}

for(j = 0;j<8;j++)
{
for(i=0;i<8;i++)
{
if(path[idex1]==i)
{
StackPush(&myStack,g.Vertices.list[path[idex1]]);
idex1=i;
continue;
}
}
}

printf("%c",Orig);
char x;
while(StackNotEmpty(myStack) != 0)
{
StackPop(&myStack,&x);
printf(">>%c",a[x]);
if(StackNotEmpty(myStack)==0)
break;
为什么进了栈以后不能显示出栈的内容？

为什么这句 printf("%c点到%c的路径为:\n",Orig,model);不能执行出来
