解题源代码：#include <stdio.h>
#include <conio.h>
unsigned long int MaxDec
     (unsigned long int a,unsigned long int b)
{
     unsigned long int c=1;
     while(c!=0)
     {
         c=a%b;a=b;b=c;
     }
     return a;
}
unsigned long int MinDec
     (unsigned long int a,unsigned long int b)
{
     unsigned long int c=MaxDec(a,b);
     return c*(a/c)*(b/c);
}
void main(void)
{
     unsigned long int y=0;
     for(unsigned long int x=1;x<2008;x++)
     {
         y=2008-x;
         if(MinDec(x,y)+MaxDec(x,y)==2008)
         {
             printf("%ld\t%ld\r\n",x,y);
         }
     }
     printf("Over\r\n");
     getch();
}
