Binary file-question!!!

[mathmari]

Hi!!!I need some help!!!
I have written the following code:

#include <stdio.h>

struct info
{
	float mo;
	int age;
}m;

int main()
{
	int il;
	FILE *fp;
	fp=fopen("sx.txt","rb");
	if (fp==NULL){
		printf("Problem!!!\n");
		exit(0);
	}
	fseek(fp,4,0);
	fread(&m,sizeof(struct info),1,fp);
	printf("Age:%d\n",m.age);
	rewind(fp);
	fread(&m,sizeof(struct info),1,fp);
	printf("Age:%d\n",m.age);
	return 0;
}

and put at the file the following numbers:
5 18
8.5 21
10 20
3 18
6 19
The first printf("Age:%d\n",m.age); does not give me the right result(19)..Why????
