[Discuss-gnuradio] c++ application

[ramanagouda odugoudar]

Hello,
 
I want to get familiar with C++ applications, for example, here input some 
integers and print the square of them( I have modified
howto_square_ff).

Now I want to input say -len=10 integers to "howto_square_vf" block and print the
same number of squared results with "ACS_outputdata_vf"

My problem is , when i run the code ... i see endless result on the screen.
Please suggest me way to achieve my above task.

//...director.cc

#include <director.h>
#include <gr_io_signature.h>
#include <howto_square_vf.h>
#include <ACS_inputdata_vf.h>
#include <ACS_outputdata_vf.h>

// Shared pointer constructor
director_sptr make_director()
{
    return director_sptr(new

 director());
}

// Hierarchical block constructor, with no inputs or outputs
director::director() : 
    gr_top_block("director")
{
   
    _len=10;
    
    ACS_inputdata_vf_sptr src= "">   
    howto_square_vf_sptr sqr = howto_make_square_vf(_len);
    
    ACS_outputdata_vf_sptr dst = ACS_make_outputdata_vf(_len);
   
    
    connect(src,0, sqr,0);
    connect(sqr,0, dst,0);
  
    
}

//....main.cc....

#include <director.h>

int main()
{
    director_sptr top_block = make_director();
    
    top_block->run(); 
     
    return 0;
}


Thanks in advance
