C++ :: How To Convert Text File Into Binary And Vice Versa

Dec 25, 2013

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.

C++ :: Text To Speech And Vice Versa

Nov 13, 2013

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?

C++ :: Converting Enum To String And Vice Versa?

Feb 25, 2014

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>>.

C/C++ :: Converting Fractions To Decimals And Vice Versa

C/C++ :: Convert TXT File To Bin And Vise Versa

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 Words[256];
char txtextension[] = ".txt";

C++ :: Convert Text File Containing 0 And 1 To Binary File

Apr 15, 2014

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;

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 :: Convert List Of Names From One Text File To Email Format In New File

Jan 19, 2014

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];

C++ :: Convert List Of Binary Numbers From A File Into Decimal And Print To Screen

Sep 23, 2014

I am trying to make a program that will convert a list of binary numbers from a file into decimal and print the decimal to the screen. I have no problem doing the conversion, the problem comes up when our teacher wants the input file in a format as such:

3
10110101
11111111
10101010

The first number is supposed to tell the program how many different 8bit strings it is going to have to convert, and then the following lines are those binary numbers.

I am not very experienced with file inputs, and I know how to open files and read lines in.. The problem is, how to say "ok the first line says 3, so now I have to convert the next 3 lines" . I am assuming it is just a simple loop that I am missing....

C++ :: Text File To Binary File

Sep 14, 2013

I want to convert a text file into binary file. I should create the text file by myself. I also use a structure for the components:

struct Data
{
int num;
char name[30];
};

I write information in the text file like this:

Data d;
cin >> d.num >> d.name;
fstream file("Name.txt");
file << d.num << d.name << '
';

If I have entered:
3 Steve
is easy to get this data. I just make another variables and get the data in them:

int num2;
char name2[30];
file >> num2 >> name2;

And everything is done. But what if I have this:

cin >> d.num;
cin.getline(d.name, 100);
file << d.num << d.name;

and the input is:
5 Steve Brown

I can get the number easy like before but how can I get the whole name? If I use:

int num2;
file >> num2;
char a[30];
file >> a;

I get only the first name "Steve". Can I get somehow and the second name in the same variable?

C++ :: Convert From Decimal To Binary With Base 2

Dec 7, 2014

I had an exercise to convert from decimal to binary with base 2, it was simple simple i did the following:

Code:
#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
void Conversion (int n);

[Code] .....

I then had an follow up exercise which was to replicate but for any base up to 10, i thought i would just have to replace 2 with a variable obtained from the user, however this did not work as i got an error saying too few arguments function but i cannot see why i am getting this.

Code:
#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
float Conversion (int n, int b);
