Read the binary file saved as a structure block and read it into the body array

See more:

C++

struct TDBDefine_Tick *data=new TDBDefine_Tick[N]; //new structure array will go wrong
TDBDefine_Tick：This is the structure block that is saved in the binary file

struct TDBDefine_Tick *data=(TDBDefine_Tick *)malloc(sizeof(struct TDBDefine_Tick )*N);
When using another new memory space, the following read will go wrong

What I have tried:

int ReadFile()
{
	 
	FILE *fp;
	if ((fp = fopen("C:\ding.bs", " rb")) == NULL)
	{
		return -1;
	}
	else
	{
		fseek(fp,0,SEEK_END);
		long size=ftell(fp);
		long N=size/sizeof(TDBDefine_Tick);
		struct TDBDefine_Tick *data=new  TDBDefine_Tick[N];
	
	for (int i=0; i<N; i++)
	{
		fseek(fp, i * sizeof(struct TDBDefine_Tick), 0); 
		fread(&data[i], sizeof(struct TDBDefine_Tick), 1, fp);
		 
		 
	}
	}
return 0;
}
