使用C的结构问题

Question

我试图将字符串存储到动态分配的内存中。我能够将字符串分解并将它们存储在结构的成员中并在函数readFile内完美打印，但是当它在main中打印时，它只能打印最后一次扫描，其他一切都是null。我想，也许我没有正确分配结构数组。这是我的计划。

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#ifdef _MSC_VER
#include <crtdbg.h>  // needed to check for memory leaks (Windows only!)
#endif

#define MEM_ERROR printf("Not enough memory\n")
#define FLUSH while( getchar() != '\n' )

typedef struct

char id[5];
char *name;
int *sales;
int total;
int low;
int high;
}PERSON;
