Re: when to use C and when to use C++

Keith Thompson:

And we'd probably end up with something like C++...

C++ has the same array/pointer conversion rules as C (though it also
has STL vectors and so forth).

<OT>

Yes, but we can have references to arrays, and we can pass an array by
reference.

void Func(int (&arr)[5]) {}

Or more exotically:

#include <cstddef>

void Func(int *p,std::size_t len) {}

template<std::size_t len>
void Func(int (&arr)[len]) { Func(arr,len); }

int main()
{
int arr[5];

Func(arr);
}

</OT>
