permute or next_permutation

[littlecompiler]

I have a program that I am to use permute to get all permuation of the numbers {0-9}. I have can do this with next_perumation but that starts on the right and moves to the left. I would like to start on the left and move to the right because I need just the firts 7 numbers ( to check a math problem). I was given the code

void permute (int v[], int curr )
{
   if ( curr >= MAX )
     checkit(v);
   else
  for ( i = curr; i < MAX; i++ )
 { 
  swap (v[i],v[curr]) // interchange the thing at  location i with the value at curr
  permute(v,curr + 1);
swap (v[curr], v[i]) 
} 
} // permute

but when I run if I add a cout I do not get the permutations. Will this work or is there a way to use next_permutatio n that will start on the left side?

next_permutatio n needs the begin and end of the range. You supplu this using bidirectional iterators. You need the range 0-7 so supply iterators that point to 0 and 8.

That should give you what you want.
