Specifying default parameters C++

I have written the following class

class worker
{
   int action;
   int doJob(int type,int time = 0);
   public:
   int call();
}

And the function doJob is like

int worker::doJob(int type,int time = 0)
{
          ....code here
}

When i compile ,i am getting the following error

 error: the default argument for parameter 1 of 'int worker::doJob(int, int)' has not yet been parsed

Surely it is a problem with default parameter specification..So what is the problem with th e prototype?

int worker::doJob(int type,int time = 0) is giving you an error, you should only declare your default argument once.

Put the default in the declaration (ie inside class worker in your example), but not in the definition, e.g. code simply:

 int worker::doJob(int type,int time)
 {  /* your code here */ }

You don't need to redefine the default value

int worker::doJob(int type,int time = 0)

can just be

int worker::doJob(int type,int time)

As you do not need to define the argument more than once.
