How do I name my member variable so it does not conflict with my local variable while following UE4 coding standard?

Say in my class I have a member variable Bar, parameter named Bar and a local variable Bar…

 class Foo{
       int Bar;
       Foo(int Bar)
       {
           int Bar;
           Bar = 1;
       }
    }

Following the coding standard from Epic how would I name them so it won’t be ambiguous?
Are we allowed to just prefix the member variable (i.e. m_Bar) and not break the standard?

Coding standard don’t mention anything about local variables naming

So use whatever you think fits. Or just rename it to whatever LocalBar

I prefix locals with “L_”.
