Bạn muốn hiểu con tro và cấu trúc vào đây nào!!!!!!!!!!!!!!!

Bài 1:
#include
#include
int main()
{
int a;
a=3;
int *p;
p=&a;
printf("Khong dung con tro de in ket qua a=%d ",a);
printf("\n");
printf("Dung con tro de in ket qua a= %d",*p);
printf("\n");
return 0;
}
Bài 2:
#include
#include
int main()
{
int a[6]={1,2,3,4,5,6};
int *p;
p=&a[0];
printf("Dung con tro trong mang de xuat ra cac phan tu\n");
printf("Xuat ra phan tu a[1]=%d\n",*(p+1));
printf("Xuat ra phan tu a[0]=%d\n",*p);
p++;
printf("Xuat ra phan tu a[1]=%d\n",*p);
getch();
return 0;
}
/*
X: vi tri phan tu trong mang
p -/+ X :chi du lieu thu X
p--/--p or p++/++p:di chuyen con tro den du lieu truoc hoac sau
p+=X or p-=X :di chuyen con tro den du lieu thu X truoc hoac sau
*/
