Hi,

I'm using a default argument in a function which compiles in project 1, but not in project 2.  I'm using Borland c++ 6.

StringTools.h:
-------------------
String removeLeadingZeros(String stInput, bool removeLastZero=true);

StringTools.cpp
-------------------
String removeLeadingZeros(String stInput, bool removeLastZero)
{
        if(stInput.Length()<1) return "";
        bool removedAZero = false;
        while(stInput.Length()>0)
        {
                if(stInput.c_str()[0]=='0')
                {
                        stInput.Delete(1,1);
                        removedAZero = true;
                }
                else break;
        }
        if(removedAZero==true && removeLastZero==false && stInput=="") stInput = "0";//if we removed the last zero, then empty string must be "0"
        return stInput;
}


While compiling this is the error I get:
[C++ Error] StringTools.h(11): E2149 Default argument value redeclared

Is this a compiler/project setting, 'cause in the other project it works fine.
Thanks for any help.

I would guess that you have the function declared in multiple places and with diffrent default values.

It looks as if you have included StringTools.h twice. The second include might give you this error.

Try to make your header safe by using

#ifndef STRINGTOOLS_H           // this protects your header beeing included twice
#define STRINGTOOLS_H          

// here you should put the contents of your header


#endif   // that is last statement of your header


Hope, that helps
