You can write a state machine that should handle most cases. As you scan the file, you’ll be in one of the following states: TEXT – regular (non-commented) text; this is the state you’ll start in. Any newline seen in this state will cause the total-lines counter to be incremented. SAW_SLASH – You’ve seen a … Read more
Good one, but it is a more clear to use listFiles(FileFilter filter) public class MyFileFilter implements FileFilter { public boolean accept(File pathname) { if (pathname.isDirectory()) return false; else { String temp[] = pathname.getName().split(“.”); if (temp[1].equals(“a”)) return true; } } } solved Searching in folder
The first issue is that the temp, temp2, and temp3 are int, but you are assigning double values to them, and then re-assigning these values back to double variables. You should make these double. You might want to consider using qsort() to sort these objects. #include <stdlib.h> // for qsort int compare_products(const void *p1, const … Read more
I am unsure what problems you are having exactly but I can see the following errors in the code: In the initialise_list() function the for loop will be iterating too many times and going beyond the bounds the of array: for(int i = 0; i < sizeof(list); i++) { as sizeof(list) will return the number … Read more

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

Keep track of the number of bytes you’re writing, and when it reaches a specified point, close the existing file and continue in a new one. There’s no need to analyze the size of the file, since you know exactly what’s going into it. Something like this: long fileSizeByteLimit = 5000000; long bytesOutput = 0; … Read more
Because DLLs are compiled. You’re looking at binary data (machine code instructions, plus various bits of data) with a text editor. While some programs are distributed as source code (bash scripts, JavaScript/HTML/CSS Windows Universal Apps, several others), many others (probably “most” on Windows) are distributed as compiled machine code. solved Why the weird language?

You can get directory for the exe file using the System.Environment.CurrentDirectory, then use the System.IO.File.Copy method to copy that file to any destination. Also for getting the current directory you may want to see this solved how to copy a file from current folder to another folder in C#
You can use File.AppendAllText() as an exact drop-in (but you’ll need to append Environment.NewLine to your text). Make sure that you delete the file if it exists before your foreach loop, possibly prompting the user for confirmation depending on your requirements. solved I want to read from and write to a file in C#
It means that IE send the png with another MIME type than “image/png” which is what you are expecting. Try to add to your array of accepted values: image/x-png Also see this What is the difference between “image/png” and “image/x-png”?. solved File upload not working in IE [closed]
I assume you have read in the lines and stored them in an array lines Then, set(lines) gives you a set that contains all unique lines. If every line is unique the length of lines and set(lines) will be the same. Ergo: if len(lines) == len(set(lines)): print ‘all lines are unique’ else: print ‘not all … Read more
