目前想要用BFS將tree以階層方式印出 //定義AVL tree的Node typedef struct Node { struct Node *lchild,*rchild; int bf; int data; }BiTNode,*BiTree; ....中間略 //印出階層tree的function void traverse(BiTree *t) { queue<BiTree*> qe; qe.push(t); while(!qe.empty()) { BiTree* pe = qe.front(); qe.pop(); cout<< pe->data; --------------------------->(1) if(pe->lchild) qe.push(pe->lchild);----------->(2) if(pe->rchild) qe.push(pe->rchild);----------->(3) } } compile一直出現(1)(2)(3)錯誤 error: request for member 'data' in '* pe', which is of non-class type 'Node*' error: request for member 'lchild' in '* pe',which is of non-class type 'Node*'| error: request for member 'lchild' in '* pe', which is of non-class type 'Node*' 想了老半天也google了還是不知道錯在哪麻煩各位前輩幫小弟看看>.< -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.37.162.221
