This can easily be done using nested loops (as I assume you'd also like 'ba bb bc' ;-)

#include <stdio.h>

void main ( void)
{
char c1, c2;

for ( c1 = 'a'; c1 <= 'z'; c1++)
{
 printf ( "%c", c1);
}

printf ( "\n");

for ( c1 = 'a'; c1 <= 'z'; c1++)
{
  for ( c2 = 'a'; c2 <= 'z'; c2++)
  {
   printf ( "%c%c", c1, c2);
  }
}
}

A little correction to 'beautify'  the output:

#include <stdio.h>

void main ( void)
{
char c1, c2;

for ( c1 = 'a'; c1 <= 'z'; c1++)
{
 printf ( "%c", c1);
}

printf ( "\n");

for ( c1 = 'a'; c1 <= 'z'; c1++)
{
  for ( c2 = 'a'; c2 <= 'z'; c2++)
  {
   printf ( "%c%c ", c1, c2);  /* note the space */
  }
 printf ( "\n");  /* a line feed when we start with a new 1st letter */
}
}

It's hard to elaborate that, as I think it's self-explaining, but please ask if you encounter problems or need more information...

Hmm, capital letter is quite easy, just use

for ( c1 = 'A'; c1 <= 'Z'; c1++)
{
  for ( c2 = 'A'; c2 <= 'Z'; c2++)
  {
   printf ( "%c%c ", c1, c2);  /* note the space */
  }
 printf ( "\n");  /* a line feed when we start with a new 1st letter */
}

instead... how would you like to use the numbers?
