In C, the size of memory allocated for integer variables varies in different compiling environments. The ansi c standard does not specify the length of the identifier, but each c compilation system has its own rules.
Integer Variables in C: Short,
Ntohs = net to host short int 16-bit
Htons = host to net short int 16-bit
Ntohs = net to host long int 32-bit
Htonl = host to net long int 32-bit
Brief description:Converts an unsigned short integer from the network byte sequence to the host byte
Communication between programs is actually sending and receiving data streams. We generally regard bytes as the smallest unit of data. Of course, a byte also contains 8 bits ). In a 32-bit processor, the "font length" is 32 bits, that is, 4 bytes.
I introduced the first part of wf4's new event-driven workflow design. We can summarize several key points.
1. The event mechanism of wf4 is revolutionary and different from that of WF3. WF3 is based on the externaldataexchange service. Wf4 is based

1.1 Introduction
G is common in the Open Source world. It represents GNU ("GNU's not UNIX "). For example, GTK +, glib, gobject, and gnome, and some other software packages, such as ghostscript and GCC, are full of G.

1. Using printf should be said to be type insecure. Therefore, the stream input and output of C ++ is introduced.
For example:
# Include "stdint. H"
# Include "iostream"
Using namespace STD;
Int main ()
{
Int64_t A = 1;
Int B = 2;
