Thread: Printf... behaving Strange...

Look at this code...

void main()
{
int arr[4]={10,20,30,40};
printf("\n%d %d %d %d\n"arr);
}


I understand that C prints all its arguements from right to left and when I say arr i refer to a[0] (first element) But the result i found was...
-18 10 20 30 40

Now, what is that -18 doing up there. If I remove a %d from the formatting list, then the last element 40 would be truncated and the result would be
-18 10 20 30

Can ny one explain this phenominan.

Course you could do something like this

Code:

void main(){
  int arr[4] = {10,20,30,40};
  for(int i=0;i<sizeof(arr);i++){
    printf("%d\n",arr[i]);
  }
}

Well,
I am aware of that method of printing out an array but my question was, "why was printf behaving so strangly". I wanted an explanation for the output of that particular code. Anyway thanks for ur time.
