Excuse me for offtopic!
Some fellow at my work gave us such a problem:
******************************
Please fix the program below with only one symbol change:
you may add one character
or
you may delete one character
or
you may replace one character
// the program must print 20 stars
main()
{
int i, N = 20;
for(i = 0 ; i < N ; i--)
printf("*");
}
There are three known solutions.
************************
I've managed to find only one
Can you help me?
