获取工人的详细信息并将其写入文件

问题描述

我还在学习C.我正在尝试编写一个程序，该程序询问工作人员数量并使用malloc函数分配内存。我创建了一个存储工人详细信息的结构。当我从用户那里获取详细信息时，一切正常，直到程序询问工人手机号码，程序停止工作。

＃包括< stdio.h> 
 #include< stdlib.h> 
 
 typedef struct 
 {
 int eid; 
 char name [50]; 
 unsigned int mobilenumber; 
}工人; 
 
 int main（）
 {
 int worker; 
 
 printf（输入工人数量：）; 
 scanf（％d，& worker）; 
 
工人* ptr; 
 ptr =（工人*）malloc（工人* sizeof（工人））; 
 
 printf（输入工人的移动数字：）; 
 scanf（％u，ptr-> mobilenumber）; 
 printf（输入工人的ID：）; 
 scanf（％d，ptr-> eid）; 
 printf（输入工人姓名：）; 
 scanf（％[^ \ n]，ptr-> name）; 
 
 printf（％d，ptr-> eid）; 
 
 free（ptr）; 
返回0; 
} 

我的尝试：



我认为问题是因为s​​canf函数而存在，但我无法找到错误。

解决方案

I am still learning C. I am trying to write a program which asks for number of workers and assigns memory using malloc function. I created a structure which stores the details of the workers. When I am taking the details from the user everything works fine until the program asks for the workers mobile number the program stops to work.

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

typedef struct
{
	int eid;
	char name[50];
	unsigned int mobilenumber;
} workers;

int main()
{
	int worker;

	printf("Enter the number of workers: ");
	scanf("%d", &worker);

	workers *ptr;
	ptr = (workers *)malloc( worker * sizeof(workers));

	printf("Enter the mobilenumber of the worker: ");
	scanf("%u", ptr->mobilenumber);
	printf("Enter the ID of the worker: ");
	scanf("%d", ptr->eid);
	printf("Enter the name of the worker: ");
	scanf(" %[^\n]", ptr->name);

	printf("%d", ptr->eid);

	free(ptr);
	return 0;
}

What I have tried:

I think the problem exists because of the scanf function but I am not able to find the fault.
