C :: Locations In The RAM Addressed Per Word Or Per Byte?
Sep 20, 2014Are locations in the RAM addressed per word or per byte? I am using a 32 bit machine, so I think that it means that on my PC a word would be 4 bytes.

Jan 29, 2014I have a complex program, around 25.000 code lines. It is quite stable, but I have a bug which only happens from time to time, and when in online-mode, so it is quite difficult for me to reproduce it. I have put lot of efforts to see where the problem is, and I have seen where the code crash, but that line is not the culprit, it only refers to read a memory location where it is supposed to be good data, and it is not. The real bug has happens before in execution. That data is read-only, I mean, I only compute it at program start-up, and then never write into it again, but my bug write to it doring code run, maybe because bad pointers address in any place, and look ramdom (different snapshots execution write at different memory locations).
My question is, is there a way to know when my code 'write' into that 'to me protected memory'? I thinking if there is a method to make a hash of all variables and arrays in that memory section, or any way to 'assert' when that big memory section is written, taking into accound that when I refer to that memory section it could be any of the lots of variables and arrays I precompute at start-up.
C++ :: Hangman Definition Game - Extract Word Randomly Form File And User Guess The Word
Jun 25, 2014Basically I have a text file called words. I'm supposed to extract a word randomly form the file and have the user guess the word. If they guess the word correctly in x number of tries they will receive the definition.
I'm having trouble receiving that random word and I'm getting the definitions from the file.
Here's my code:
#include <iostream>
#include <fstream>
#include <string>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
using namespace std;
[Code] ....
This is what is in the words.txt file
apple#the usually round, red or yellow, edible fruit of a small tree
boat#a vessel for transport by water
horse#a solid-hoofed plant-eating domesticated mammal with a flowing mane and tail, used for riding
television#a system for transmitting visual images and sound that are reproduced on screens
soup#a liquid dish, typically made by boiling meat, fish, or vegetables, etc.
bottle#a container, typically made of glass or plastic and with a narrow neck

C++ :: How To Read A Bit From A Byte
Mar 30, 2013What is the most efficient way to read a bit at a particular position in a byte?
View 13 Replies View RelatedC++ :: String To Int To Byte?
Aug 16, 2014Right now im creating a program that use xbox inputs and then send out keyboard functions using sendInput();
It works fine, but now im creating a system wich lets the user of the program change the settings in a textfile. Wich will then change what the controllers bindings are.
example, if settings.txt says: Y=button(0xIE)
i want the program to know that when xbox button Y is pressed, execute a sendInput function to the Key: A (0xIE).
The problem is that the virtual keycode (0xIE) i take from the settings.txt is stored as a string (lets say it is stored in string Y_event)and input.ki.wScan has to be of type BYTE. i made a function wich changes string into int. (because input.ki.wScan seems to be fine getting a int?)
int stringToInt(string insert) {
char back[20];
for(unsigned int e=0;e < insert.length();e++) {
back[e]=insert[e];
} return atoi(back);
}
but when i run the code nothing happend...
In the code i have a function wich executes the keypress: void pressbutton(int key, int time)
when i send in the converted string it doesn't work but when i send in: (0xIE) it works.
pressButton(stringToInt(Y_Event),50) // doesn't work
pressButton(0xIE,50) // works
focus on the last part that i wrote.

C :: Byte Ordering In Binary Buffer
Apr 13, 2014Basically it has to do with the byte ordering in a binary buffer vs the typing of a variable used to hold it.
To give you an example, if I have a buffer (say of indefinite length), and a ptr "ptr" pointing to a byte in the buffer (say, C0), such that if I open the buffer in a binary viewer it reads like this: Code: C0 DD FE 1F Such that this is true:
Code:
/*ptr is uint8_t*/
*ptr == 0xC0
Then I do this:
Code:
uint16_t var;
var = *(ptr+1);
I would expect the result to be:
Code: DD FE /*56830*/
Though if I print that out with:
Code:
printf("%u
", var);
It'll print:
Code: 65245 /*(FE DD)*/
Now obviously it's byte swapped, but what is causing that? I'm assuming if I just stream that out to a file byte by byte it'll be fine, so it's something with the 16 bit data type (also have seen this issue with a 32 bit data type, where all 4 are in reverse order). Is there any way to 'fix' it except bit shifts & masks?
C# :: Reading A File Into A Byte Array?
Jun 25, 2014I basically want to create a save editor application that will enable people to alter various values in the save by clicking on releveant buttons and then also for the editor to auto update the checksum when changes are done.
The save file is in hex so from what I can gather I would need to create a button to open the file using 'open file dialogue' and then read the file into a byte array so that the values can be called at any time when a particular butto is pressed and the application will then seek to the point in the file to make the required changes.
C# :: Get Posted File From Byte Array
Oct 7, 2014I have an application that has its own embedded web server. I am trying to add jQuery/Ajax file upload capabilities to the application however, I am running into issues getting the posted file. The jQuery/Ajax portion is similar to this method here. Due to the way the webserver was written (its in a dll and I do not have access to the source), the posted file comes in as a byte[]. If I try to save the byte array directly to file using:
File.WriteAllBytes("path", ByteArray)
I end up with a corrupt file that I cannot open. I believe this is because the byte array also contains the posted file header info (Content-Disposition, name, filename, etc.). If I view the contents of the byte array using:
System.Text.Encoding.Default.GetString(ByteArray)
the header info can be viewed as:
------WebKitFormBoundaryQfPjgEVpjoWgA5JL
Content-Disposition: form-data; name="0"; filename="someimage.png"
Content-Type: image/png
‰PNG
Based on the selected file size and the size of the byte array, the entire file is in the byte array. How can I go about extracting and saving the posted file from the byte array?

C++ :: Binary IO - Read 4 Byte Int From A File
Feb 26, 2012Trying to write very simple code to read a 4 byte int from a file.

fread(&tester,sizeof(int),1,fp);
printf("tested 1 byte read should be 1: %i",tester);
I have tried editing the binary file....it outputs similar large numbers
00000000000000000000000000000001 outputs 808464432
0x00000001 outputs 808482864
0x10000000 outputs 808548400
10000000000000000000000000000000 outputs 808464433
x01 x00 x00 x00 outputs 813183068
x00 x00 x00 x01 outputs 813183068 same....
etc.etc. It just keeps returning the same large integers. I thought they were memory addresses but its consistent output/input so I guess not.

View 7 Replies View RelatedC++ :: Byte Array To Double Conversion?
Dec 5, 2014I'm trying to understand why a conversion from a byte array (unsigned char) to a double works when done one way and not antoher.
In the example code I test by hard coding an unsigned char array of the same bytes that the double consists of.
When I copy the bytes to a long long and cast to double the result is not the original double but if I use a struct the bytes can be set and the conversion happens.
Seems to me that both ways should work. I'd just like to know what is going on with the "struct way" that makes the conversion correct. I see in debugger that the bytes in memory are the same for piAsLong and u.bytes.
My compiler is VS 2012 and a long long and double are both 8 bytes (tested with sizeof). This is learning activity only.
Code:
#include "stdafx.h"
#include <iostream>
#include <iomanip>
using namespace std;
union {
double d;
