{
ans = n*i;

I used to think that in C99, even if the side-effects of functions f and g interfered, and although the expression f() + g() does not contain a sequence point, f and g would contain some, so the behavior would be unspecified: either f() would be called before g(), or g() before f().
I am no longer so sure. What if the compiler inlines t...

The two strings may overlap; the copy is always done in a non-destructive
manner.
From the C99 standard:
