The file content 111 111 222 222 333 333 444 444

CodePudding user response:

See you first read length whether there are so many data, then the sread reset after initialization, read it again

CodePudding user response:

What is QQzm. TXT in the content? Determine the text characters?

CodePudding user response:

Recommended WinHex software to check the hard disk or file or original bytes of memory content,

Computer memory or file content or transport it is just a one-dimensional binary byte array and its corresponding binary address;
The human brain to a computer memory or file contents or transfer the content of the one-dimensional binary byte array and its corresponding binary address some parts as an integer, number of signed/unsigned number, floating point Numbers, complex Numbers, letters, digits, Chinese/Korean/French... Character/string, assembly instructions, functions, function parameters, heap, stack, arrays, Pointers, array pointer and pointer array, the array of arrays, pointer to pointer, two-dimensional arrays, character lattice, the coordinates of character strokes, black and white binary images and grayscale images, color images, audio, video, fingerprint information, id information...

With ue to view the following read text files, is there something else behind
Array before using memset 0 x0
Step through see monitoring numerical change

CodePudding user response:

FileQ. Read Read (sread, n) to see if the return value is n, the other in binary view software view under the end of the file what extra bytes,

Ps: pop-up box function parameters for character set, MessageBoxW MessageBox see instead,

CodePudding user response:

Should be the problem of file size
