I want to read a txt file line by line. I am getting the error"the device is not ready". I can't understand what the problem is? The code is as follows: #include<stdio.h> #include<stdlib.h> int main(int argc, char **argv) { char command[100]; char line[10]; FILE* fp = fopen("input.txt","r"); while (fgets(line, sizeof line, fp) ...
Hi. I am trying to make a simple program that handles files and directories, but I have two major problems: how can I check whether a file or directory exists or not, and how do I know if it is a file, directory, symbolic link, device, named pipe etc.? Mainly file and directories matter for now, but I'd like to know the others too. ...
Most of the requirements for a game programming job I've looked at required good C/C++ skills. I agree, most game engines are written in C/C++. But aren't the engines USED in a scripting languages? Don't the companies need scripting programmers to actually code the game from the game engine? Why haven't I ever seen a company that requir...
I need to write a standalone (not under XULRunner) c/c++ application (Windows OS) that uses XUL as its backend GUI library. If it is possible, can you give me a link to an example application ? I saw something about libXul, is it needed ? where can i find it ? TNX, Vertilka ...
I'm parsing HTML with libxml2, using XPath to find elements. Once I found the element I'm looking for, how can I get the HTML as a string from that element (keeping in mind that this element will have many child elements). Given a document: <html> <header> <title>Some document</title> </header <body> <p id="...
Hello, I am planning to use an Arduino programmable board. Those have quite limited flash memories ranging between 16 and 128 kB to store compiled C or C++ code. Are there ways to estimate how much (standard) code it will represent ? I suppose this is very vague, but I'm only looking for an order of magnitude. ...
I have a program which creates some combinations of strings like if i entered input abc it gives me output as bcs cab abc #include<stdio.h> #include<string.h> int main() { char str[15]; int i,j,n; printf("Enter a string"); scanf("%s",str); n=strlen(str); for(i=0;i<n;i++) { str[n]=str[0]; fo...
I need access to the uint64_t typedef from stdint.h in some wrapper code that I'm writing and I can't figure out how to get it done. The problem is that from what I can tell from the docs, my ctypedef will have to take the form: ctypedef unsigned long uint64_t or ctypedef unsigned long long uint64_t depending on if WORDSIZE from bi...
When generating VS2010 targets with CMake, I would like the /LTCG flag turned on (only for release + releasewithdebinfo if possible, but its okay if its on for debug builds). How do I modify the linker flags? add_definitions() doesn't work because that only modifies compiler flags. And yes, I have wrapped it in if(MSVC). How do I modify...
I'm using a naive approach to this problem, I'm putting the words in a linked list and just making a linear search into it. But it's taking too much time in large files. I was thinking in use a Binary Search Tree but I don't know if it works good with strings. Also heard of Skip Lists, didn't really learn it yet. And also I have to use...
I'm testing a 2D OpenGL ES based iPhone game on both the iPhone 3G and the iPhone 4. It runs great on the iPhone 4... and pretty well on the 3G. The game state is updated at 60 Hz... and the rendering is done at 60 fps. Would the following conversion from Objective-C to c improve the performance at all? // current Objective-C functio...
I'm passing a simple user-defined type (UDT) from Visual Basic 6 to a C DLL. It works fine, except for the double data type, which shows up as 0. C DLL: #define WIN32_LEAN_AND_MEAN #include <windows.h> #include <stdio.h> typedef struct _UserDefinedType { signed int Integer; unsigned char Byte; float Float...

I'd like to interpret a command string, recieved by a microcontroller (PIC16f877A if that makes any difference) via serial. The strings have a pretty simple and straight-foward formatting: $AABBCCDDEE (5 "blocks" of 2 chracters+'$' for 11 characters in total) where: $AA= the actual name of the command (could be letters, numbers, both; m...
since last four years i had been coding in c/c++, but those lenthy programs made me sick of them. then i got to know about python, and i have learned the basics. python seams to be more flexible and powerful than c++... But i want to know is python realy better than c++? if yes/no in what ways , please explain. since i am a student ,...
Hi, I was using some gnome applications like empathy and gwibber, and was wondering how to create a "conversation" effect in my own gtk application. E.g. http://www.ubuntu.com.cn/files/1004features/01.jpg (off google, not my site) Thanks ...
I'm working on Windows with the Quicktime-API and I wonder, how to get the start timecode (SMPTE) of a movie file? Can someone post a link or an example how to do that? ...
For example, I have this string: SMUL 9 A B? How can I get 9 (int type) A (char) and B (char). Possible string may be SMUL 12 A C, so it means their positions in the string is not constant. Further explanation: this is a string inputted by a user for my matrix calculator program. Inputting SMUL "scalar" "matrix-1" "matrix-2" means that ...
