Extra number?

When I run this program, the first number that is printed is some odd number like 134508085, why does it print that first instead of the number I input first?

Code:

---

#include <stdio.h>

int main( int argc, char *argv[] ){

  int a[10];
  int i;

  printf("Enter ten numbers: \n");

  for(i = 0; i < 10; i++){
    printf("%d> ", i+1);
    scanf("%d", &a[i]);
  }

  for(;i >=0; i--) 
    printf("%d \n", a[i]); 

  return 0;
}

When you hit the second for loop, i == 10, which is outside of the bounds of your array.
