Error: request for member 'Name' in something not a structure or union

Question

我正在尝试编写一个程序，将文本文件（data2.txt）中的数据读取到动态数组中。然后将该数据打印到屏幕上。当我运行我的程序出现如下错误时：

Error: request for member 'Name' in something not a structure or union.

我不明白为什么会出现此错误，因为我在我的程序中包含了一个包含结构的头文件。数组 P 的大小是文件中的第一个整数。任何 help\guidance 将不胜感激。

这里是文本文件的内容data2.txt:

5
Martin Smith     22 2.2
Austin Clinton   18 3.1
Johnson          19 2.9
Maggie Jones     23 2.3
Tyler W Brown    16 3.4

这里是头文件的内容：

typedef struct RECORD
{
char Name[15];
int Age;
float Gpa;

};

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

int main()
{

int n;
int number = 0;
int i=0;


FILE * fpointer;
    fpointer = fopen("data2.txt", "r");

    fscanf(fpointer,"%d",&number);
    n = number;

    printf("Size value is: %d \n", n);

   int *P = malloc(n*sizeof(int));

[错误显示在下一行]

  fscanf(fpointer,"%s %d %f", P[i].Name , &P[i].Age, &P[i].Gpa);

   while(! feof(fpointer))
   {
    printf("%s %d %.1f\n",P[i].Name , P[i].Age, P[i].Gpa);
     fscanf(fpointer, "%s %d %f",P[i].Name , &P[i].Age, &P[i].Gpa);

     i++;
   }



free(P);


fclose(fpointer);

printf("\n\n");
system("PAUSE");
return 0;
}

Answer 1

int *P = malloc(n*sizeof(int));

这里P是一个int类型的指针，你需要的是

struct RECORD *p = malloc(n * sizeof(struct RECORD));

p 应该是 struct RECORD

类型的指针

c

pointers
