The condition i  j 1 will not be true for i  2  This can be fixed by a couple of changes to the inner loop    include  lt stdio h gt  int main void     for  int i 2  i lt 100  i         for  int j 2  j lt  i  j         Changed upper bound         if  i    j      Changed condition and reversed order of if s       printf   d n  i       else if  i j    0        break
