十一级指针实现百万qq号的增删查改以及排序写入

發布時間：2024/8/26 编程问答 35 豆豆

生活随笔收集整理的這篇文章主要介紹了十一级指针实现百万qq号的增删查改以及排序写入小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

運行結果:

內存使用情況:

寫入文件排序好的數據:

創建文件地址以及創建十一級指針 1 char *path = "QQ.txt"; 2 char *sortpath = "QQchiguowei2018.txt"; 3 //創建十一級指針 4 char *********** allP = NULL;
初始化十一級指針

1 //初始化2 void init()3 {4 5 FILE *pf = fopen(path, "r");6 if (pf==NULL)7 {8 9 printf("文件打開失敗"); 10 return; 11 } 12 else 13 { 14 //讀取每一行加載到allP中 15 for (int i = 0; i < allN; i++) 16 { 17 char str[50] = { 0 }; 18 fgets(str, 50, pf);//讀取 19 char *tmpstr = convertQQ(str);//獲取QQ號 20 21 if (isallnum(tmpstr)) 22 { 23 assignmem(&allP, 11, tmpstr);//分配內存 24 25 strcpy(allP[getnum(tmpstr[0])][getnum(tmpstr[1])][getnum(tmpstr[2])][getnum(tmpstr[3])][getnum(tmpstr[4])][getnum(tmpstr[5])][getnum(tmpstr[6])][getnum(tmpstr[7])][getnum(tmpstr[8])][getnum(tmpstr[9])], str); 26 27 } 28 } 29 } 30 fclose(pf); 31 }
字符串轉提取qq號的函數

1 //字符串提取qq號2 char *convertQQ(char *str)3 {4 int length = strlen(str);//獲取長度5 char *tmp = malloc(length + 1);6 strcpy(tmp, str);//拷貝，避免數據自動回收7 //獲取第一個'-'的位置8 char *p = strchr(tmp, '-');9 if (p!=NULL) 10 { 11 *p = '\0'; 12 13 } 14 int count = strlen(tmp);//獲取QQ長度 15 //如果長度小于10,則在前面置零,轉換成十位,最后一位/0也寫入,所以要從下標10開始,一共11位 16 if (count< 10) 17 { 18 for (int i = 10; i >= 0; i--, count--) 19 { 20 if (count>=0)//移動 21 { 22 tmp[i] = tmp[count]; 23 } 24 else 25 { 26 //填充0 27 tmp[i] = '0'; 28 } 29 } 30 } 31 return tmp; 32 }
判斷是不是全是數字

1 //判斷是不是全是數字2 int isallnum(char *str)//判斷是否有非法字符3 {4 while (*str)5 {6 if (*str<'0' || *str>'9')7 {8 return 0;9 } 10 11 str++; 12 } 13 return 1; 14 15 }
獲取對應數字 1 //獲取對應的數字 2 int getnum(char ch) 3 { 4 return ch - '0';//0 1 5 }
分配內存 ?深度表示前面還有幾顆星如果還有一顆星則進行內存分配,剛開始前面有十一顆星

1 //分配內存深度表示前面還有幾顆星如果還有一顆星則進行內存分配,剛開始前面有十一顆星2 void assignmem(char **pp,int deep,char *str)3 {4 //如果前面有一顆星5 if (deep==1)6 {7 //分配內存獲取qq號最后一位的數字8 pp[ getnum(*(str + 10 - deep))] = malloc(sizeof(char) * 50);9 //內存清零 10 memset(pp[getnum(*(str + 10 - deep))], 0, sizeof(char) * 50); 11 return; 12 } 13 14 //如果前邊有十一顆星 15 if (deep==11) 16 { 17 if (allP) 18 { 19 assignmem(*pp, deep - 1, str);//遞歸調用 20 return; 21 } 22 else 23 { 24 //allP指向十個十級指針 25 allP = malloc(sizeof(char**********) * 10);//分配指針數組 26 memset(allP, '\0', sizeof(char*) * 10);//清零 27 assignmem(*pp, deep - 1, str);//遞歸調用 28 return; 29 } 30 } 31 32 //如果已經分配內存 33 if (pp[getnum(*(str + 10 - deep))]) 34 { 35 //遞歸調用 36 assignmem(pp[getnum(*(str + 10 - deep))], deep - 1, str); 37 } 38 //否則分配內存 39 else 40 { 41 pp[getnum(*(str + 10 - deep))] = malloc(sizeof(char*) * 10); 42 memset(pp[getnum(*(str + 10 - deep))], 0, sizeof(char*) * 10); 43 assignmem(pp[getnum(*(str + 10 - deep))], deep - 1, str);//遞歸調用 44 } 45 }
查詢

1 //查詢2 void search(char *str)3 {4 //判斷是不是數字5 if (isallnum(str)==0)6 {7 return;8 }9 //如果查詢的長度大于10 10 if (strlen(str)>10) 11 { 12 return; 13 } 14 15 //格式化成10位 16 char *tmp = malloc(11); 17 int count = strlen(str); 18 if (count<=10) 19 { 20 for (int i = 10; i>=0; i--,count--) 21 { 22 if (count>=0) 23 { 24 tmp[i] = str[count]; 25 } 26 else 27 { 28 tmp[i] = '0'; 29 } 30 } 31 } 32 else 33 { 34 printf("NO NO"); 35 return; 36 } 37 38 //依次判斷內存是否存在 39 if (allP[getnum(tmp[0])]) 40 { 41 42 if (allP[getnum(tmp[0])][getnum(tmp[1])]) 43 { 44 45 if (allP[getnum(tmp[0])][getnum(tmp[1])][getnum(tmp[2])]) 46 { 47 48 if (allP[getnum(tmp[0])][getnum(tmp[1])][getnum(tmp[2])][getnum(tmp[3])]) 49 { 50 51 if (allP[getnum(tmp[0])][getnum(tmp[1])][getnum(tmp[2])][getnum(tmp[3])][getnum(tmp[4])]) 52 { 53 54 55 if (allP[getnum(tmp[0])][getnum(tmp[1])][getnum(tmp[2])][getnum(tmp[3])][getnum(tmp[4])][getnum(tmp[5])]) 56 { 57 if (allP[getnum(tmp[0])][getnum(tmp[1])][getnum(tmp[2])][getnum(tmp[3])][getnum(tmp[4])][getnum(tmp[5])][getnum(tmp[6])]) 58 { 59 if (allP[getnum(tmp[0])][getnum(tmp[1])][getnum(tmp[2])][getnum(tmp[3])][getnum(tmp[4])][getnum(tmp[5])][getnum(tmp[6])][getnum(tmp[7])]) 60 { 61 62 if (allP[getnum(tmp[0])][getnum(tmp[1])][getnum(tmp[2])][getnum(tmp[3])][getnum(tmp[4])][getnum(tmp[5])][getnum(tmp[6])][getnum(tmp[7])][getnum(tmp[8])]) 63 { 64 if (allP[getnum(tmp[0])][getnum(tmp[1])][getnum(tmp[2])][getnum(tmp[3])][getnum(tmp[4])][getnum(tmp[5])][getnum(tmp[6])][getnum(tmp[7])][getnum(tmp[8])][getnum(tmp[9])]) 65 { 66 67 printf("%s\n", allP[getnum(tmp[0])][getnum(tmp[1])][getnum(tmp[2])][getnum(tmp[3])][getnum(tmp[4])][getnum(tmp[5])][getnum(tmp[6])][getnum(tmp[7])][getnum(tmp[8])][getnum(tmp[9])]); 68 return; 69 70 } 71 72 73 } 74 75 } 76 77 78 79 } 80 81 82 } 83 84 } 85 86 } 87 88 } 89 90 } 91 92 } 93 94 printf("沒有找到"); 95 96 }
