this is a very simple programe,but the last line "printf" is very clever.
do you think so?Code:main()
{
int a,b,c,count=0;
printf("There are different methods for XM to distribute books to 3 readers:\n");
for(a=1;a<=5;a++)
for(b=1;b<=5;b++)
for(c=1;a!=b&&c<=5;c++)
if(c!=a&&c!=b)
printf(count%4?"%2d:%d,%d,%d " : "%2d:%d,%d,%d\n",++count,a,b,c);}
