(In reply to re: Poor AWK people... by Erik O.)

#include <cmath>
main {
for (int a=0; a!=10; a++)
  for (int b=0; b!=10; b++)
    for (int c=0; c!=10; c++)
      for (int d=0; d!=10; d++)
        if (  ( (int)pow(a,b) * (int)pow(c,d) ) == (a*1000 + b*100 + c*10 + d) )
          return (a*1000 + b*100 + c*10 + d);
return (-1);}

And I included the return statements and declared all the variables!
