code
1 #include <stdio.h> 2 int main(void) 3 { 4 int a[3][4]={ 5, 10, 15, 20, 5 25, 30, 35, 40, 6 45, 50, 55, 60}; 7 8 printf(" a=%08x\n", a); 9 printf(" a+1=%08x\n\n", a+1); 10 11 printf(" *a=%08x\n", *a); 12 printf(" *a+1=%08x\n\n", *a+1); 13 14 printf(" **a=%08x\n",**a); 15 printf(" **a+1=%08x\n\n", **a+1); 16 17 printf(" &a=%08x\n", &a); 18 printf(" &a+1=%08x\n\n\n\n\n\n", &a+1); 19 20 printf(" %08x ",&a[0][0]); 21 printf("%08x ",&a[0][1]); 22 printf("%08x ",&a[0][2]); 23 printf("%08x\n\n",&a[0][3]); 24 25 printf(" %08x ",&a[1][0]); 26 printf("%08x ",&a[1][1]); 27 printf("%08x ",&a[1][2]); 28 printf("%08x\n\n",&a[1][3]); 29 30 printf(" %08x ",&a[2][0]); 31 printf("%08x ",&a[2][1]); 32 printf("%08x ",&a[2][2]); 33 printf("%08x\n\n",&a[2][3]); 34 35 getchar(); 36 return 0; 37 }
