Hey All,  
This question might be a little stupid but what shell command would  
one  
have to use to edit an existing c++ block , just modify it a tad bit(  
not  
add functionality to it) but print statements in general to see the  
outputs  
of the block.

Thanks and regards,  
Anay.

[directed at nobody in particular, nothing personal]  
But I’ll point out that this isn’t the right forum for learning  
very-basic software/computer skills like editing a simple text file. We  
must  
necessarily assume that you have those basic skills. This is,  
after-all, _software_ defined radio, rather than, for example,  
social-psychology-defined radio, or  
comparative-mid-17th-century-literature-defined radio, or  
watching-football-defined radio.  
So, it shouldn’t perhaps come as a big surprise that basic _software_  
development skills are rather a requirement.
