c - Floating point formatting in printf() -

-

I have an array of float where the data is stored with decimal points, so some 123.40000 < / Code> 123.45000 , 123.45600 ... now if I want to print these values ​​without typing 0 in the printf () They are finally without <0>, 123.4 , 123.45 , 123.456 . Is this possible? if so, how?

Use% g formatatter: 

  Printf (" G ", 123.4000); 123.4  
 123.4  
 123.4  
 Trail zero is removed, but unfortunately, decimal is the decimal point, if partial part is zero. I do not know if there is any way of actually doing whatever you want to use printf () - I think that something like this is probably your best bet:  
  #include & Lt; Stdio.h & gt; # Include & lt; Math.h> Zero print (FILE * f, double d) {if (d - floor (d) == 0.0) {fprintf (f, "% g.", D); } And {fprintf (f, "% g", d); }} Int main () {Print (stdout, 12.0); Print (standout, 12.300); }

SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

I do not understand why this script does not work. It has something to do within AJAX PostScript / Function. Right now, when I submit my form, it runs php code on the same page.
