C++ Extension functions?

Question

Are there extensions for C++ like there are in C#?

For example in C# you can do:

public static uint SwapEndian(this uint value)
{
    var tmp = BitConverter.GetBytes(value);
    Array.Reverse(tmp);
    return BitConverter.ToUInt32(tmp, 0);
}

someuint.SwapEndian();

Is there anything like that in C++?

Answer 1

There are no extension functions in C++. You can just define them as free functions.

uint SwapEndian(uint value){ ... }
