readfile

问题 Hello I'm on a project who require me to find a string interval multiples times (from display_url to display_resources ) in a .txt file. For now I have my code like this but when I'm running it, it never break . The goal of this code is to : Search the strings from the le1 / le2 index as starting point. Update the new found index from the dat / det variables to le1 / le2 [to go to the next string interval in the .txt file (in my test they are four of them)] Add the le1 & le2 variables to the

问题 I am reading a file into a SCALAR by using: open FILE, "<", $filename or error_out("Error opening $filename"); read FILE, my $buffer, -s $filename; close FILE; I am not sure how to think of the "new" $buffer / SCALAR type. Is it a string? An array? How to go through it line-by-line? 回答1: First, I recommend you use the following to read the file: my $buffer = do { open(my $fh, '<', $filename) or error_out("Error opening $filename: $!"); local $/; <$fh> }; Note the removal of the useless and

问题 I'm currently using the following code to download files from my Amazon S3 account. if(isset($_POST['file_name'])) { $bucket = $_POST['bucket']; $fname = $_POST['file_name']; $accessKey = 'AKIAIEHFBME6F5Q62FTQ'; $secretKey = '<REMOVED>'; $file_type = pathinfo($fname, PATHINFO_EXTENSION); $mp3_url = el_s3_getTemporaryMP3Link($accessKey, $secretKey, $bucket, $fname); $zip_url = el_s3_getTemporaryZipLink($accessKey, $secretKey, $bucket, $fname); if ($file_type === "mp3") { header('Content-type:

问题 I am trying to develop a GUI-based program to read the entries of a matrix from a text file. The first number is the number of rows; the second number is the number of columns. The remaining numbers are integers between 1 and 9 in row by row order. Scan the matrix, highlight (display the entries in different color) all cells that form a group of five cells with the same value horizontally, vertically or diagonally. My program below is NOT reading the file correctly I don't think because every

问题 ( Edit: I didn't exclude any code except the headers and the main() function's brackets. Nothing is written between lines of code listed here.) . I used the ReadFile function to read this COM3 port (which returned no INVALID_HANDLE_VALUE or ERROR_FILE_NOT_FOUND): LPCTSTR portName = "COM3" ; HANDLE hSerial; hSerial = CreateFile(portName, GENERIC_READ | GENERIC_WRITE, 0, // exclusive access NULL, // default security attributes OPEN_EXISTING, FILE_FLAG_OVERLAPPED, NULL); And the ReadFile

问题 I will enhance an old algorithm which use java language and i want it to read the text from file to encrypt it SO I will make a method that reads the text line by line from file then store them in array. I made this method and it works BUT the variable "line2" reads the first line correctly but once the next line come it will erase the first line and put the second line so what can i do please?? // The CODES Private byte[] line2; public byte[] readFromFile (){ try (BufferedReader br = new

问题 When I run the program, the numbers I'm getting are completely ridiculous such as -39389014 when the number in the text file is 20. Here is what my text file looks like: 20 20 40 30 80 40 90 20 60 10 18.0 And the Code: #include <stdio.h> #define SIZE 5 int main(void){ FILE *in = fopen("pfile1.txt", "r"); int x[5], y[5], i; double h; for (i=0;i<SIZE;++i){ fscanf(in, "%d %d", &x[i], &y[i]); } for (i=0;i<SIZE;++i){ printf("%4d %10d\n", x[i], y[i]); } fscanf(in, "%lf", &h); printf("%lf\n", h);

问题 I am trying to write a program in C++ that emulates a college enrollment system, where the student enters their ID, and the program searches a text file for their information, and loads a struct based on the text file. I have gotten to a point where I am having trouble getting their enrolled courses into the struct's array. Using the getline function, using the ',' as the delim will also carry over the next line until the next comma. What would be the correct algorithm for this? This is the
