Question

设计一个通讯录，里面有名字，微信号和电话号码，下面是我的程序
#include <stdio.h>
#include <string.h>
#define N 3

struct people
{
char name[10];
char weixin[15];
char phone[15];
}p[N];
int main()
{
void input(struct people p[]);
void input(struct people p[]);
struct people *find(struct peope p[],char str[]);
struct people *a;
char str[8];
input (p);
output (p);
printf("input finding name: ");
scanf("%s",str);
a=find(p,str);
if(a==NULL)
printf("not find\n");
else
printf("%-10s%-15d%-15c",a->name,a->weixin,a->phone);
return 0;
}
void input (struct people p[])
{
int i;
for(i=0;i<N;i++)
{
printf("input data of people %d:\n",i+1);
printf("name: ");
scanf("%s",p[i].name);
printf("wexin: ");
scanf("%d",p[i].wexin);
printf("phone: ");
scanf("%c",p[i].phone);
printf("\n");
}
}
void output (struct people p[])
{
int i;
printf("\n name weixin phone\n");
for(i=0;i<N;i++)
{
printf("%-10s%-15d%-15c",p[i].name,p[i].weixin,p[i].phone);
printf("\n");
}
}
struct people * find(struct people p[],char str[])
{
int i;
for(i=0;i<N;i++)
{
if(strcmp(str,p[i].name)==0)
return &p[i];
}
return NULL
}

修改好了，

#include <stdio.h>
#include <string.h>
#define N 3

struct people
{
    char name[10];
    char weixin[15];
    char phone[15];
}p[N];
int main()
{
    void input(struct people p[]);
    void output(struct people p[]);
    struct people* find(struct peope p[], char str[]);
    struct people* a;
    char str[8];
    input(p);
    output(p);
    printf("input finding name: ");
    scanf("%s", str);
    a = find(p, str);
    if (a == NULL)
        printf("not find\n");
    else
        printf("%s %s %s\n", a->name, a->weixin, a->phone);
    return 0;
}
void input(struct people p[])
{
    int i;
    for (i = 0; i < N; i++)
    {
        printf("input data of people %d:\n", i + 1);
        printf("name: ");
        gets(p[i].name,10);
        printf("wexin: ");
        gets(p[i].weixin);
        printf("phone: ");
        gets(p[i].phone);
        printf("\n");
    }
}
void output(struct people p[])
{
    int i;
    printf("\n name weixin phone\n");
    for (i = 0; i < N; i++)
    {
        printf("%s %s %s", p[i].name, p[i].weixin, p[i].phone);
        /*puts(p[i].name);
        puts(p[i].weixin);
        puts(p[i].phone); */
        printf("\n");
    }
}
struct people* find(struct people p[], char str[])
{
    int i;
    for (i = 0; i < N; i++)
    {
        if (strcmp(str, p[i].name) == 0)
            return &p[i];
    }
    return NULL;
