But line by line is more fun:

  void p_string(int n, int v[])

Throw out return type, argument type and give the method  a rubyesque name:

  def chunky_chunky_bacon(chunky, bacon)

  {
lose the burly bracket.

  int i;
get rid of the local declaration.

  cout<<"\nThe string is : ";

cout is called STDOUT, you don't need semicolons, and the string
you're printing isn't ruby enough;

  STDOUT << "\nWelcome to the madhouse :"

  for(i=0;i<n;i++)

for loop is different

  for ding_dong in 0..chunky-1


   cout<<v[i]<<"  ";
turns into
   STDOUT << bacon[dingdong] << " " # this should look familiar by now
   end

end the closely curly brace
   }
becomes:
   end

Putting it all together:

void p_string(int n, int v[])
{
int i;
cout<<"\nThe string is : ";
for(i=0;i<n;i++)
   cout<<v[i]<<"  ";
}

becomes:

def chunky_chunky_bacon(chunky, bacon)
  STDOUT << "\nWelcome to the madhouse :"
  for ding_dong in 0..chunky-1
    STDOUT << bacon[ding_dong] << " "
  end
end
