Help please

[caroundw5h]

I"m trying to have the output as discribed in my code however i seem to have the logic messed up

forget the fact that i haven't put it to uppercase yet, i'll do that later. The code seems to have the desired results in terms of the structure, but the characters are all wrong. Is there a math problem here?
#include <stdio.h>
int main(void){
/* output   A
            BA
            CBA
            DCBA
            EDCBA  */

 /* output is structure i want but not letters */
 int r,c;

 for(r = 0; r <= 5; r++){
    for (c = 'a'; c<=('a' + r); c++){
       printf("%c", r - c);  /* this is correct algorithm for the structure */
    }
     printf("\n");

  }
  getchar();
  return 0;
  }

P.s. if the color bothers you guys, i was just testing out the vb code, won't do it again

[Prelude]

Close:

#include <stdio.h>

int main ( void )
{
  int r, c;

  for ( r = 0; r < 5; r++ ) {
    for ( c = 'A' + r; c >= 'A'; c-- )
      printf ( "%c", c );
    printf ( "\n" );
  }

  return 0;
}

Thanks alot prelude. I hope your not as beautiful as your inteligent that would be a real lethal combination.

Now to go see what i did wrong.
