7.2Record结构中的程序存在编译器错误

编程问答 2022-06-07

问题描述

我想编写以下程序，但出现错误。我该怎么办？该程序的内容。

  1. 记录输入（无效）：从标准输入（键盘）到 结构
  2. void output（Record）：将结构内容输出到标准 输出（显示在显示屏上）
  3. int main（）：定义结构变量数据。呼叫输入和 分别输出一次。
  4. 对上述程序进行了进一步的修改（主要功能的修改） 并添加函数int getage（Record））以对应数据 两个人。
  5. 将结构变量数据更改为带有 元素数量2，并使用prog02a.c函数输入和输出 在上一个问题中创建以从标准输入中输入数据 并输出到两个人的标准输出中（未更改 输入或输出功能）。
  6. 此外，使用结构元素作为参数，创建一个 int getage（Record）函数可在返回时返回完整年龄 参考日期，请从main调用此函数，以便 每个人也会显示。但是，记录日期为十月 2020年1月1日，并将由宏给出。

prog02b.c源代码。

#include <stdio.h>
#include "prog01.h"
#define YEAR 2019
#define MANTH 10
#define DAY 1

Record input (void);

void output (Record);

int getage (Record);

int main () {
  
  int i;
  
  Record data [2];

  printf ("-------- data entry -------- \ n");

  for (i = 0; i <2; i ++) {
    
    printf ("% dth",i + 1);
    
    data [i] = input ();
  }

  printf ("\ n -------- data output -------- \ nage base date:% d year% d month% d day \ n",YEAR,MANTH,DAY);
  
  for (i = 0; i <2; i ++) {
    printf ("% dth data: \ n",i + 1);
    
    output (data [i]);

    printf ("First name (last name):% s \ n First name (first name):% s \ n Date of birth:% d year% d month% d day \ n Age:% d \ n",data.familyname,data. firstname,data.birthday [0],data.birth>
  }
    
  return 0;
}

Record input (void) {
  Record data;
  
  printf ("Enter data \ n");
  
  printf ("first name (surname)->");
  scanf ("% s",data.familyname);

  printf ("name (first name)->");
  scanf ("% s",data.firstname);
  
  
  printf ("Year of birth (AD)->");
  scanf ("% d",& data.birthday [0]);
  
  printf ("month of birth->");
  scanf ("% d",& data.birthday [1]);
  
  printf ("date of birth->");
  scanf ("% d",& data.birthday [2]);

  printf ("Gender (0: Male,1: Female)->");
  scanf ("% d",& data.gender);

  return data;
}

void output (Record data) {
  printf ("First name (last name):% s \ n First name (first name):% s \ n Date of birth:% d year% d month% d day",data.firstname,data.birthday [1],data.>
  
  if (data.gender == 0)
    {printf ("(male) \ n");
  
    } else {printf ("(female) \ n");
  }
}

int getage (Record data) {
  if (data.birthday [1]> = MANTH) return YEAR-data.birthday [0] -1;
  else return YEAR-data.birthday [0];
}

prog01.h 

typedef struct
    char familyname[20]; // first name (last name)
    char firstname[20];  // name (first name)
    int birthday[3];     //Birthday (Element 0: A.D. Element 1: Month Element 2: Day)
    int gender;        //Gender (0:Male,1:Female)
Record.

“ | ^”每个错误点都是data.familyname，data.firstname，data.birthday [0]，data.birthday [1]，data.birthday [2]。

解决方法

有很多问题。我已对它们进行了更正，因此您的程序可以正确编译，而不会出现错误或警告。

但是我不知道它是否确实应该做。

#include <stdio.h>

typedef struct
{
  char familyname[20]; // first name (last name)
  char firstname[20];  // name (first name)
  int birthday[3];     //Birthday (Element 0: A.D. Element 1: Month Element 2: Day)
  int gender;        //Gender (0:Male,1:Female)
}
Record;

#define YEAR 2019
#define MANTH 10
#define DAY 1

Record input(void);
void output(Record);
int getage(Record);

int main()
{
  int i;
  Record data[2];

  printf("-------- data entry --------\n");

  for (i = 0; i < 2; i++) {
    printf("%dth",i + 1);
    data[i] = input();
  }

  printf("\n -------- data output -------- \nage base date:%d year%d month%d day\n",YEAR,MANTH,DAY);

  for (i = 0; i < 2; i++)
  {
    printf("%dth data:\n",i);
    output(data[i]);

    printf("First name (last name): %s\n First name (first name): %s\n Date of birth: %d year %d month %d day\n age: %d\n",data[i].familyname,data[i].firstname,data[i].birthday[0],data[i].birthday[1],data[i].birthday[2],getage(data[i]));
  }

  return 0;
}

Record input(void) {
  Record data;

  printf("Enter data \n");

  printf("first name (surname)->");
  scanf("%s",data.familyname);

  printf("name (first name)->");
  scanf("%s",data.firstname);


  printf("Year of birth (AD)->");
  scanf("%d",&data.birthday[0]);

  printf("month of birth->");
  scanf("%d",&data.birthday[1]);

  printf("date of birth->");
  scanf("%d",&data.birthday[2]);

  printf("Gender (0: Male,1: Female)->");
  scanf("%d",&data.gender);

  return data;
}

void output(Record data) {
  printf("First name (last name):%s \n First name (first name):%s \n Date of birth:%d year %d month %d day",data.familyname,data.firstname,data.birthday[0],data.birthday[1],data.birthday[2]);

    if (data.gender == 0)
    {
      printf("(male) \n");
    }
    else 
    {
      printf("(female) \n");
    }
}

int getage(Record data) {
  if (data.birthday[1] >= MANTH) return YEAR - data.birthday[0] - 1;
  else return YEAR - data.birthday[0];
}
