C++ :: Read Byte Of Char Data And Convert It Into Text String Of Binary Data That Represents Hex Value

Dec 26, 2013

I am writing a program where I need to read a byte of char data and convert it into a text string of binary data that represents the hex value...

i.e. The char byte is 0x42 so I need a string that has 01000010 in it. I've written the following subroutine....

------------- My Subroutine ----------------------------------------------------------------------
void charbytetostring(char input, char *output){
int i, remainder;
char BASE=0x2;
int DIGITS=8;
char digitsArray[3] = "01";

[Code] ....

When I submitted the byte 0x42 to the subroutine, the subroutine returned to the output variable 01000010... Life is good.

The next byte that came in was 0x91. When I submit this to the subroutine I get garbage out.

I am using a debugger and stepped through the subroutine a line at a time. When I feed it 0x42 I get what I expect for all variables at all points in the execution.

When I submit 0x91 When the line remainder = input % BASE; gets executed the remainder variable gets set to 0xFFFF (I expected 1). Also, when the next line gets executed..

input = input / BASE; I get C9 where I expected to get 48.

My question is, are there data limits on what can be used with the mod (%) operator? Or am I doing something more fundamentally incorrect?

C++ :: How To Convert Bytes To ASCII

Feb 7, 2014

How can I convert bytes to ASCII?, I read wikipedia about UTF-8 and I understood a little bit about add or split bytes to change the value.

Now I have those bytes

0xC7 0xE6 0xC2 0x91 0x93 0x7B 0xCE 0x01

And I found a program (DCode) that convert to 64 bits little-endian, supposedly those bytes in ASCII is this.

C :: Program To Convert Bits To Bytes

May 13, 2013

I made this program to convert bits to bytes, because I'm so sick of seeing ISP's advertise speeds in megabits, which I consider an intentional attempt to decieve :P And I think I've finally understood how the return value of scanf works since the last time I posted here, so my program can check to see if an integer was entered before processing the input, but I'm stuck on how to make the whole program start over if an integer is not entered. I have a hunch it would involve a loop, but I can't figure out how to make the program start over at "How many mb do you need converted?" if an integer is not entered into scanf..Here is the code I have so far:

Code:

#include <stdio.h>
int main () {
int b, mb, kb, Byte, kB, mB, gB;
char term;
}

[code]....

and my program makes the assumption for now at least, that mb will be inputted because that's the unit of measurement that i usually see advertised, and i didn't bother making an if statement to print a conversion in terms of gigabytes because i've never heard of a connection that fast :P

Visual C++ :: Convert 8 Bytes Into Double And Back?

Sep 5, 2013

I receive a byte stream. The first 8 bytes contain an Identification number. I receive at first the lowest byte and at the end the highest byte of the number. How can I transform this into a double value and later back into the bytestream? In the past I hard only 2 Byte values and there I could use things like MAKEWORD and HIBYTE and LOWBYTE to convert the values

C++ :: How To Convert String To Double Without Changing Actual Data

Jun 3, 2013

I have to convert string to double. i'm using "atof" function to achieve same.

I have string as "0.0409434228722337" and i'm converting with "atof" But i'm getting double value as "0.040943422872233702". Why it adds 02 additionally at the end?

More example :

"0.0409434228722337" converts to "0.040943422872233702"
"0.067187778121134" converts to "0.067187778121133995"

Is there any other possibility to convert string to double without changing data ?

C++ :: Convert String Variable For The Year To Integer Data Type

My intent was to convert the string variable for the year to an integer data type. The code compiles but now cannot run on my system. I'm not sure what's going as to what the program is displaying.

Objective: Prompt the user for two years. Print all Comedy movies that were released between those two years.

#include <iostream>
#include <cstdlib>
#include <string>
#include <fstream>

C/C++ :: Read Bytes From A Data File

Dec 5, 2014

I am a member of a group still developing the Microprose European Air War game. We have the source code and permission to do this. As the code dates back to 1998 I use Visual Studio 2006.

I have written many programs in Visual basic, and have the following one to read the airbase value in the "targets.dat" file. The file has a four byte header containing the number of tatgets, and a 32 byte data block containing the data for each target.

Private Sub Command1_Click()
List1.Clear
Dim nt As Long
Dim a4() As Long  
Open App.Path & " argets.dat" For Binary Access Read As 1
'read and display the number of targets  

[Code] ....

Despite many attempts I cannot write the C equivalent of this code into the eaw.exe source. All I really need to know is how to open the 'targets.dat' file and how to get the value of a byte (or integer, or long) at a given position as in the "Get #1, k, a4(n)" line.

Visual C++ :: Array Of Bytes To String

Feb 22, 2013

Using a table with the 256 bytes as strings, said table is used as a reference in the 2 functions of this code. Functions who make the conversion such as the title establishes, and in the inverse way too.

The main advantage is that you don't need any knowledge about managing bytes with c++..

Code:

#include <windows.h>
#include <stdlib.h>
#include <stdio.h>
char* hextabla[] = { //256 BYTES
"00","01","02","03","04","05","06","07","08","09",
"0A","0B","0C","0D","0E","0F","10","11","12","13",

[Code] ....

I leave the project in MSVCPP 6, see attachment...

It's ready to compile in 'Release' mode.

C++ :: Why Address Of Object Is 6 Bytes And Not 8 Bytes On 64 Bit Linux

Mar 24, 2013

Code:
int i12 = 1001;
cout << i12 << " " << &i12 << endl;

gives the result: 0x7fff0d065098

It's 6 bytes, but I'd expect the address to be 8 bytes on my 64 bit machine. I am using Ubuntu 12.04, GNU compiler.

So, why the address is 6 bytes and not 8 bytes?

I am using Visual Studio 2008. I just wonder if there are any library function in Windows SDK or MFC, or from third-parties, that can convert a UTF-8 string into Windows Unicode string(used in CString object).

Can MultiByteToWideChar or ATL String conversion macro like A2W to the conversion?

C++ :: Convert A Value Into A String?

May 21, 2013

I would like to convert a value into a string, and extract a value from a string. And then call these functions in the main.

Are above functions correct? And how should I call in main?

int main() {
const int SIZE=10;
toString<int> intValue(SIZE); //seems not right
toString<double> doubleValue(SIZE); // seems not right
