last should be also a template function like the code below, but it doesn't work.

I alsoe get missing return type with ctor: SercureString( const char* s );.

Nice to see that your problem got solved.

your class name was SecureString, not SercureString,

#pragma once
class SecureString

public:

    SecureString();

SecureString::SecureString( const char* s )
