Question

Here is a recursive code using side effects in function argument.In K&R, i found a statement
saying C standard specifies that all side effects on arguments take effect before a function is called(page no.54 K&R second edition).But output to above code was contradictory.Could anyone help me out.

void reverse(int* array,int i,int j)
{
  `int temp;
  if(i>j)

    return ;
  else{
    temp=array[i];
    array[i]=array[j];
    array[j]=temp;
    //i++;
    //j--;
    reverse(array,i++,j--);
  }
} '

PS:Output is segmentation fault

Answer 1

all side effects are completed, so the value of i and j is changed before function call.

but the value of express i++ and j-- are still the value of i and j previously.
