1) You check feof() first, then do a fscanf(), and then don’t check its return value (or re-check feof() at the very least. (You might have been right at the end of the file prior to the fscanf() call, or the configuration file might be malformed, but you wouldn’t detect this with your code.) 2) … Read more
The video may be going over your maximum upload size. To increase your maximum upload size, add the following lines to your .htaccess file: php_value upload_max_filesize “200M” php_value post_max_size “200M” (Replace “200M” with whatever you want the maximum to be – “200M” means “200 megabytes”.) Some hosts may not allow you to change those settings, … Read more
The readLine function does look a bit error prone: char * readLine(FILE * fin){ char buffer[BMAX]; int i,j; char ch; char * l; i = 0; ch = getc(fin); if (ch == EOF) return NULL; while (ch!=’\n’ && i < (BMAX – 1)){ buffer[i] = ch; i++; ch = getc(fin); } // The test on … Read more
Perhaps you could read the file one character at a time. Test each character that you read to see if it is a newline character (‘\n’). If it is not a newline character, print the character that was read. If it is a newline character, print “\n”. Good Luck!

The stated problem, that no file is created, is impossible to answer with the information given. It is most likely due to an invalid file path. However, the OP states in a comment that the path in his example is not the real code. EDIT: the hex string example that I cited originally was wrong, … Read more
As others have commented you probably have an iterator, not a list; You can use itertools.tee to get two independent iterators from same iterable: >>> from itertools import tee >>> a = [1, 2, 3] >>> fst, snd = tee(iter(a)) # two copies of same iterator >>> >>> list(fst) # exhaust the first iterator [1, … Read more

FileOutputStream fos = FileOutputStream(“path/to/the/file/to/write/in”); fos.write(theByteArray); fos.close(); Will write the byte array in byte form. FileOutputStream fos = FileOutputStream(“path/to/the/file/to/write/in”); for (byte b : bytes) { fos.write(String.format(“%02X “, b).getBytes()); } fos.write(theByteArray); fos.close(); Will write byte array in human readable form.

printf() prints to stdout. You need to fopen() that file and then use fprintf() with the returned from fopen() FILE* pointer as the first argument. /* Open the file for writing */ FILE* fp = fopen(“filename.txt”, “w”); /* Check for errors */ if (fp == NULL) { /* Notify the user of the respective error … Read more
