C语言制作通讯录怎么将联系人的名字按26个字母的顺序排序

Posted 2023-04-20

用 strcmp(name1,name2) 作比较，name1 > name2 做交换。
当然 要把名字（字符串）全化成大写或全小写再比较。
假定都是小写：
#include<stdio.h>
struct TXL

char name[20]; char phone[20]; char address[50]; // 你还可以添别的项，不一定是 char 型
;

#define N 4 // 例子里用 4 个人
int main()

struct TXL txl[N]= "zhang","12345","abcd",
"wang","12345","efg",
"li","12345","hijk",
"zhao","12345","xyz"; // 声明结构数组，并初始化，当然你可以改用输入语句输入
struct TXL t; // t 用来 排队比较交换时，用作 工作单元
int i,j;
for (i=0;i<N-1;i++)
for (j=i;j<N;j++)
if (strcmp(txl[i].name,txl[j].name) > 0) // 比较
t=txl[i]; txl[i]=txl[j];txl[j]=t; // 交换


for (i=0;i<N;i++)
printf("%s %s %s\n",txl[i].name,txl[i].phone,txl[i].address); //输出结果
参考技术A 按26个字母的顺序排序

实现以下功能

• 获取手机通讯录数据
• 数据分组显示(中文英文正确分组)
• 点击索引进行跳转
• 滚动到特殊位置进行特别处理
• 联系人查询
