[Error] cannot convert 'int*' to 'char*' for argument '1' to 'char* s_gets(char*, int)'

初学c语言 想了好久 不知道是那里出了问题

[棉猴]

问题出在 s_gets(list[count].phone  , PHONE); 中list[count].phone的定义是int的指针，而s_gets函数的第一个参数需要的是char的指针，所以会报错

[幻夢之葉]

phone是int类型，你s_gets的第一个参数要求的是char*类型 解决方式： 1：把phone修改为char[]类型 2：定义一个临时字符数组，读取char*的数据，然后再转化为你的phone

[你我的约定]

phone是int类型，s_gets的参数要求的是char*类型

[自信男孩]

phone的类型是什么，要根据你的需求。如果这个phone是代表手机名（厂商），建议定成char phone[PHONE]类型；

#include <stdio.h>
#include <string.h>


#define MAXTITL 40
#define PHONE   20
#define NUM     50

struct people {
    char name[MAXTITL];
    char phone[PHONE];

int main()

    struct people list[NUM];
    int count = 0;
    int index;

    printf("please enter the name:");
    while (count < MAXTITL && s_gets(list[count].name , MAXTITL) != NULL && list[count].name[0] != '\0')
    {
            printf("now please enter the phone number:");
            s_gets(list[count].phone  , PHONE);
            while (getchar() != '\n')
                continue;
            if (count < NUM)
                printf("enter the next title.\n");
