The following is a detailed analysis of the use of the SSCANF function in C language, the need for friends under the reference Name: sscanf ()-Reads data from a string that matches the specified format. Copy Code code as follows: function

Transferred from: http://blog.csdn.net/eroswang/article/details/5160220 Summary: 1, 80x86 uses the small end method (that is, the local byte order), the network byte order uses the big-endian method. 2, binary network programming, the transfer of

(0) Background: The traffic on the network is a byte stream, and for a multi-byte value, the bytes are passed in the network transmission. That is, when the receiving end receives the first byte, does it handle the byte as a high or low? (1)

Linear queueThe queue is FIFO, and the stack is reversed.The non-circular queue is a waste of space, if the tail to the maximum, even if the front of the team, there are empty positions, can no longer queue.Seqqueue.h #ifndef __seqqueue__ #define _

Here's an example: rounding to keep the two digits after the decimal point The code is as follows Copy Code $num 1 = 21;Echo sprintf ("%0.2f", $num 1). " "; Output 21.00$num 2 = 16.3287;Echo sprintf ("%0.2f", $num 2). "

Let's take a look at how the C standard I/O library functions are implemented using system calls. fopen (3) Calling open (2) Opens the specified file, returns a file descriptor (that is, an int type number), assigns the file structure, which
