What do you think will be the output of this code? If you're not sure, try it.
Code:
for (i=5;i<10;i++)
{
printf("%d \n",acc[i].account_number);
printf("%s \n",&acc[i].account_type);
printf("%d \n",acc[i].balance);
}
Also you might want to try this code so that you can see why I said i=5:

Code:
int i;
for (i=0; i<5; i++)
{
printf("Inside loop, i=%d\n",i);
}
printf("After loop, i=%d\n",i);
