You can only use functions that exist.

This function

ucgen(int c)
{
  cout<<"hello"<<endl;
}

tries to use the default constructor of sekil to create its sekil base object. It tries to use the default constructor because you didn't specify what constructor to use.

The default constructor of sekil is sekil() , which does not exist.

You cannot use functions that don't exist.

Can you see your code? Are you satisfied with how it looks? Maybe try using code tags:

your code goes between the tags
