Okay so here's the thing...I came across a code of my classmate that i'm not familiar with...the only thing i know is the printf is the same as cout...right??can someone explain this in iosteam.h form??

#include <stdio.h>

void bubble_sort(long [], long);

int main()
{
  long array[100], n, c;

  printf("Enter number of elements\n");
  scanf("%ld", &n);

  printf("Enter %ld elements:\n", n);

  for (c = 0; c < n; c++)
     scanf("%ld", &array[c]);

  bubble_sort(array, n);

  printf("Sorted list in ascending order:\n");

  for ( c = 0 ; c < n ; c++ )
      printf("%ld\n", array[c]);

  return 0;
}

void bubble_sort(long list[], long n)
{
  long c, d, t;

  for (c = 0 ; c < ( n - 1 ); c++)
  {
     for (d = 0 ; d < n - c - 1; d++)
     {
        if (list[d] > list[d+1])
        {

          t         = list[d];
          list[d]   = list[d+1];
          list[d+1] = t;
        }
     }
  }
}

I was effin surprised that this code worked in my Turbo c++ 4.5 compiler...i'm really not used to this kind of coding...Note: I understand the loop but the printf, scanf,%d...etc....please explain further..:)

wait i think the only thing to explain is....scanf("%ld", &n);....i dont get it...

%ld is used because the datatype is long.

in c++ u can directly use cin>>n;

This is basically a C code. cout = printf() , cin = scanf().
Other things are basically same, but some are different for example in C we use malloc(), calloc() to dynamically allocate memory, in C++ we use 'new'. To use these properly you need to learn C language.
