the correct way is: int myreadfile(void) { FILE *fp; int i, n; unsigned char a[50]; if (!(fp=fopen(“x.exe”,”rb”))) return(0); while(n=fread(a,1,sizeof(a), fp)) { for (i=0; i<n; i++) printf(“%02x “,a[i]); printf(“\n”); } fclose(fp); return 1; } Note that the buffer is of type unsigned char. That is because a) you don’t know if the file is a complete … Read more

Your 2nd fgetpos is probably a typo for fsetpos. That would explain the behaviour you comment on: pos2 is replaced now with a new value let us say 18. update after your edit: now both calls are fsetpos???. You need to get the position somewhere, and then go back to it with set later. 7 … Read more
BufferedWriter bw = new BufferedWriter( new OutputStreamWriter( new FileOutputStream(new File(“path of the output file”)), “UTF-8”)); Or in java 7 use Files.copy. 4 solved read special characters from a file and write in another file using java [duplicate]
The solution I came up with is as follows: public void AppendFile(string filePath, long firstWord, long lastWord) { using (StreamWriter sw = File.AppendText(filePath)) { for (long i = firstWord; i < lastWord; i++) { sw.WriteLine(GetWord(i)); } } } public void AppendFile(string filePath, long lastWord) { AppendFile(filePath, 0, lastWord); } public void AppendFile(string filePath) { AppendFile(filePath, … Read more
Case In-Sensitive Windows file system is case insensitive by default. solved C# file extensions
If you are trying to delete this lines from the file, try this: import os def removeUrl(url): url_file = “url.txt” fileIn = open(url_file, ‘r’) fileOut = open(“temp.txt”, ‘w’) for line in fileIn: if url not in line: fileOut.write(line) fileIn.close() fileOut.close() os.remove(url_file) os.rename(“temp.txt”, url_file) removeUrl(“www.youtube.com”) solved python – history file
EDIT: Since according to the OP, the code is in a function, and score is defined, this is more than likely a case of the computer being a jerk. Restart should theoretically solve the problem. The code’s logic is correct as it stands. Syntactically, there are two major problems: it must be in a function, … Read more
Your glob isn’t correct. You should add a /* to the end of your path to select all files (or directories) in your path, and then check if they are files with os.path.isfile. Something like: from os.path import isfile files=filter(isfile,glob.glob(‘%s/*’%path)) You also have an issue with the actual opening. When your with statement ends, the … Read more
I thought about the question some more. There are filesystem-specific ways to create the possibility of truly hidden files, of course, but I’m not at all interested in exploring those. However, there is a different approach, a variant, that might suit your needs. You could achieve a similar effect by intercepting only the open syscall … Read more
You are printing the last value only. So you are getting the result only 13.You have to write the value in the for loop. b = open(‘new’, ‘w’) for n in [4, 7, 8, 10, 6, 3, 5, 13]: if n > 5: print(n) b.write(n) 1 solved Writing integers into a new file
The .h usually has the class definition (code) #ifndef CLASS_T_H #define CLASS_T_H class class_t { public: class_t(); class_t(const class_t& o); ~class_t(); class_t& operator=(const class_t& o); private: }; #endif And the .cpp usually has the class implementation (code) #include “class_t.h” class_t::class_t() { } class_t::class_t(const class_t& o) { } class_t::~class_t() { } class_t& class_t::operator=(const class_t& o) { … Read more
Is XSLT the right choice to interpret CDATA in a certain way and write to a file? Yes, CDATA is just a (part of a) text node and is processed as any other text node. Yes, the XSLT 2.0 xsl:result-document instruction is used to write to (possibly many different) file(s). .2. Use some sort of … Read more
The problem is that you are declaring your string array inside the loop and never populating it with anything. Move that string array outside the loop instead. Also, I don’t think you want to write the file every time through the loop, so move file write outside the loop too. static void Main(string[] args) { … Read more
