Disabling bounds checking for c++ vectors

Question

With stl::vector:

vector v(1);
v[0]=1; // No bounds checking
v.at(0)=1; // Bounds checking

Is there a way to disable bounds checking

Answer 1

Based on your comment that you would like to turn on/off bounds checking, you could use a wrapper template function:

template 
inline typename T::reference deref(T &cont, typename T::size_type idx)
{
#if BOUNDS_CHECK
    return cont.at(idx);
#else
    return cont[idx];
#endif
}

template 
inline typename T::const_reference deref(const T &cont, typename T::size_type idx)
{
#if BOUNDS_CHECK
    return cont.at(idx);
#else
    return cont[idx];
#endif
}

You would have to modify your code to enable this, but once you had it in place you could turn bound checking on or off as you wish.

I do admit that it looks a bit ugly to use:

deref(vec, 10) = ...;
