好長時間沒碰數據結構了 寫的挺亂的 看來要多練啊
有個輸入報數不能從1報到1的bug

運行效果

請輸入總節點個數:100
從1開始報到幾？3
3 6 9 12 15 18 21 24 27 30 33 36 39 42 45 48 51 54 57 60 63 66 69 72 75 78 81 84 87 90 93 96 99 2 7 11 16 20 25 29 34 38 43 47 52 56 61 65 70 74 79 83 88 92 97 1 8 14 22 28 35 41 49 55 62 68 76 82 89 95 4 13 23 32 44 53 64 73 85 94 5 19 37 50 67 80 98 17 40 59 86 10 46 77 26 71 31 100 58
剩余的數字：91
請按任意鍵繼續. . .

代碼

#include<iostream> using namespace std;typedef struct LinkList {int num;LinkList* pnext; }List, *plist;void add(plist *pphead, plist *pptail, int num) {plist pnew = (plist)malloc(sizeof(List));pnew->num = num;//插入if (*pphead == NULL){*pphead = pnew;*pptail = pnew;pnew->pnext = *pphead;}else{(*pptail)->pnext = pnew;*pptail = pnew;pnew->pnext = *pphead;//成環}}int main() {plist phead = NULL;plist ptail = NULL;cout << "請輸入總節點個數:";int total;cin >> total;int left = total;int i;for (i = 0; i < total; i++){add(&phead, &ptail, i + 1);}int end;cout << "從1開始報到幾？";cin >> end;int chu = end;int j, k;plist pcur = phead;plist pbefore = pcur;for (i = 0; i < total; i++){pbefore = pcur;if (left == 1){cout << endl;cout << "剩余的數字：" << pcur->num << endl;break;}//到這個刪除for (j = 0; j < end - 1; j++){pbefore = pcur;pcur = pcur->pnext;}//刪除pbeforecout << pcur->num << ' ';pbefore->pnext = pcur->pnext;free(pcur);pcur = pbefore->pnext;left--;}system("pause"); }
