问题 I am attempting to write an array of the first N primes to a txt file in rows of 5 entries each, with 10 spaces between each entry. The relevant code is as follows: #include<stdio.h> #include<math.h> #define N 1000 ... void writePrimesToFile(int p[N], char filename[80]) { int i; FILE *fp = fopen(filename, "w"); for(i = 0; i<=N-1; i++) { for(i = 0; i<5; i++) { fprintf(filename, "%10%i", p[i]); } printf("/n"); fclose(fp); } printf("Writing array of primes to file.\n"); } The compiler throws the

问题 Is there a way to search the entire computer and get the full file path of specified file, given a filename to match against? If you enter for example "file.dat" in textbox it show you full file path if it exist? 回答1: Look into the Directory class in System.IO .

(In your case the entire C drive) As per the MSDN documentation: Enumerable collections provide

问题 I am making a new post regarding this case because I was misunderstood in the first one... I have a code that reads the serial data from the Arduino and when some specific digits are pressed on the keyboard it writes these digits to the Arduino. This exact code works perfectly when I run it , it reads the serial data and I am able to write data to the Arduino. I use threading and PySerial library to achieve this. from pynput import keyboard import threading import serial import sys ser = None
