C/C++ :: Convert TXT File To Bin And Vise Versa
Feb 15, 2014
I am having a problem with converting a .txt file into a .bin file. It wokrs but only creating a new file and not being able to actually convert it, i have to do this using the fstream functions. I have already created the files in the project file e.g if i type file . file.txt is in the folder.
Here is my Binconvert function -
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
fstream fMyFile;
char Name[256];
char Words[256];
char txtextension[] = ".txt";
char binextension[] = ".bin";
[Code] ....

The problem is that I want to write a C++ program that converts an ordinary text file into binary and then reads that binary file and converts it to text file so that this text file equals to first text file. I have wrote this code for it.
int main() {
string name1 = "first", name2 = "sec", name3 = "third";
int j = 0, k = 0;
ifstream ifs(name1.c_str()); // Here I want to read from the ordinary text file (name1).
[Code] .....
Now what the ofs.write(as_bytes(j), sizeof(int)); or ifs.read(as_bytes(k), sizeof(int)); exactly mean?
In practice, the file name1 contains digit 5 and its size is 1 byte. The name2 contains some character/sign like [] and its size is 4 bytes and name3 contains digit 0 and its size is 1 byte, why? I before have created the name1 file in ordinary text file mode.
My machine is Windows 7 32-bit. My compiler is MVS 2012.

I was looking for a C++ library for use as stated in the title. I was considering using Voce; however, for the project, I wanted to be able to use a custom voice. For example, in most TTS programs you can pick voices. I wanted to record a custom one. However, I don't really know how these libraries work internally, and since the text to speech is referred to as synthesis, it seems they are created through algorithms rather than recordings. Is there any library which I could use a custom recorded voice with?

It is working:
#include <iostream>
#include <string>
#include <vector>
#include <map>
const int ENUM_NOT_FOUND = -1; const std::string NEW = " ";
enum Day {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday};
[code]....
Ouput with GCC 4.8.1:
Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
Name a day: Friday
day = Friday
But the problem is that whenever I define a new enum, I have to define the << and >> overloads for the new enum again. Isn't there a way to template that as well, so that the << and >> overload needs to be defined just once? My atttempt:
template<typename Enum>
std::ostream& operator << (std::ostream& os, Enum en) {
return os << EnumConversions<Enum>::toString (en);
[Code] .....
fails to compile. I guess the problem is Enum is not known at compile time, even though it should be deducible during run time? Error mentions ambiguous overload for operator>>.

I'm working on a Fraction Class assignment where I'm supposed to provide conversion operators to allow Fraction objects to be used in expressions containing float data values. The way I have it now, I'm getting an error that says operator float(const Fraction &) must contain 'void', which makes no sense to me. Lines 155 - 173.

I have almost a hundred names in a text file that I want to convert to email addresses and save to another file. I seem to have it working, but it doesn't print the full names in the email prefix. The output I'm looking for is Doe_John@livebrandm, but I'm only getting D_J@livebrandm. I'm not sure what I should specifically be reading up on that applies to this directly.
Code:
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
FILE *fpin=fopen("namesIN.txt", "r");
FILE *fpout=fopen("emailOUT.txt", "a");
char first[20],last[20],inbuff[1500];

I just wrote a program for Huffman Encoding, where I take a text file, encode it in the form of 0's and 1's, and save that as another text file. However, this does not solve my purpose as it is taking even more space.
So I want to know how do I convert a text file containing these 0'S & 1's to a binary format.
Here is my program:
#include <stdio.h>
#include <string.h>
#include<fstream>
#include<string>
#include<iostream>
using namespace std;
typedef struct node_t {
struct node_t *left, *right;
int freq;
char c;

I am developing a program that convert PDF files to TIFF files. I use imagemagick++ and can accomplish the concersion successfully. But the resolution of the multi-page TIFF files is too low. My code follows:
vector<Image> imageList;
for(int i = 0; i < imageList.size(); i++) {
imageList[i].resolutionUnits(PixelsPerInchResolution);
imageList[i].density("300");
}
readImages( &imageList, "E:/gk11.pdf" );
writeImages( imageList.begin(), imageList.end(), "D:/gk11.tif" );
Although I change the density in the code, but it seems don't work.

I am trying to rewrite a matlab code into c++. It reads a file and do the deresolution on it and convert it to 8 bit.
but the VC++ code does not work for all ranges of max_den and min_den. Specially when the there is a small difference between them. (I tried that range on Matlab, it works)
MATLAB Code:
fid = fopen(ORIGINAL_FILENAME,'r');
A = fread(fid,X*Y*Z,'int32=>int32')
D = uint8(255/double(Maximum_Density-Minimum_Density)*(A-Minimum_Density));
A = reshape(D,X,Y,Z);
fid=fopen(OUTPUT_FILENAME,'w');
[code].....
For example when actual range of data is [-3023,3072] and the max_den=-3000, min_den=1000, it works well. but when you choose max_den=-1000, min den=1000, it doesn't work properly.The raw file includes 3D data associated with a mhd file. When the range is not wide enough, the converted file becomes messy.

there is a way to convert a file's name into a string.
Sample:
filename = testcode.txt
it will convert the file's name into a string:
char convert[100];
covert = name of file
Is this possible?

I defined
enum boundaryType_t {inside, inlet, outlet, wall, periodic};
now I have file written like this:
inside outlet
I want my program read the file and when encounter any enum type, instead of treating it as a string, I want the program store it in memory as a enum value.
How can I do that?
string s;
ifs>>s;

I am working on a program which turns a 256 color bmp image to a txt file of a array of 0-255. I wrote this:
#include<iostream>
#include<fstream>
// if 1 , see bmp file header info
#if 1
#define SEE_INFO
#endif
using namespace std;
[Code] ....
Something weird happened. When I use it on simple.bmp (Attachment), it works fine. But when I use it on flower.bmp , it just give me zeros.
Attached File(s)
simple.bmp (3.39K)
simple.txt (8.47K)
flower.bmp (76.05K)

I'm looking to convert audio, images, video to base64 in c++, and through many searches on the web I've only seem to come up with string > base64.
When I view a .mp3 file for example, there are many characters there that are not available to be used in my string to encode.
[URL] ....
I have this code set up in my project, and all I want is to be able to give the location of any file and have it encode (could just encode to a string, I can handle writing it to a file), and then give a location to put the decoded file as well.
I'm not sure exactly where to even start.
