c - 如何将值传递给结构变量然后将结构写入文件？

Question

如何将值传递给结构变量 我试图从用户那里获取员工信息，然后将它们写入文件，但在输入员工姓名后出现了段错误。这是我的代码。

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

struct record_em{
    int id;
    char name[20];
    int salary;
    int age;
};

int main( void )
{
    struct record_em employee;
    FILE *fp;
    int id, salary, age;
    char name[20];
    int n=1;

    fp = fopen("empRecord.dat","a");
    while(n==1){
        printf("\nEnter Employee ID\n");
        scanf("%d",&id);
        employee.id=id;
        printf("\nEnter Employee Name\n");
        scanf("%s",name);
        employee.name=name;
        printf("\nEnter Employee Salary\n");
        scanf("%d",&salary);
        employee.salary=salary;
        printf("\nEnter Employee Age\n");
        scanf("%d",&age);
        employee.age=age;
        fwrite(&employee,sizeof(employee),1,fp);
        printf("Enter 1 to add new record \n");
        scanf("%d",&n);
    }

    fclose(fp);

    return 0;
    }

输出(取自评论):

Answer 1

改变

scanf("%s",name);
employee.name=name;

到

scanf("%s",name);
strcpy(employee.name, name);

更好的是，正如 Dukeling 和 hmjd 所建议的那样

scanf("%19s", employee.name);
