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

Aug 1, 2014

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.

// Fractions CLASS

C++ :: Convert String Of Hex To Char

Jul 5, 2013

I have this code working:

tmp_wku[2]=0x62;
char tmp_com[11];

This sends the buffer to a LIN modem. My question is: can this be done better. If I have a astring of hex numbers like "09 98 88 55 42 FF 00 00 FF BD 89". How could I send this without manually makng a char with hex numbers?

C/C++ :: Convert Char Variables To String?

Apr 17, 2013

I need to find some sort of method to convert a series of char variables to a string, to be shown in a label. I've searched for two days and experimented myself just as long, and the closest I've gotten simply puts ASCII values into the string with the following command:

label1 -> Text = System::Convert::ToString(fdp8), System::Convert::ToString(fdp7), 
System::Convert::ToString(fdp6), System::Convert::ToString(fdp5), 
System::Convert::ToString(fdp4), System::Convert::ToString(fdp3), 
System::Convert::ToString(fdp2), System::Convert::ToString(fdp1);

fdp1-fdp8 are all char variables.

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 Char To Const Char

Jun 3, 2013

I have a file which contains a year and the name of an associated file to be read. I need to extract the data in the txt file and perform some calculations.

( year data file)
2004 2004data.txt
2005 2005data.txt
2006 2006data.txt

Here is what I do. I first declare "char yeardata" and then pass "2004data.txt" to it. Then I call yeardata in ifstream to extract the data inside the file "2004data.txt". The problem is that char yeardata is not constant so I cannot pass the file to it. It doesn't work if I change "char yeardata" to "const char yeardata".

Code:
int oldnewcomp_temp(char* lcfile) {
using namespace std;

int year;
char yeardata;

[Code] ....

C++ :: How To Convert Char Into Numeric Value

Jan 1, 2015

when I was looking for a way how to convert char into numeric value for std::cout I found some old discussion with this statement: Operations on unsigned int are typically faster than on unsigned char, because your processor cannot fetch single bytes but has to get at least a multiple of 4 and mask out the other 3 bytes. Is this true? By using smaller (in bytes) variable I actually slow down my program? I always thought that it is a good practice if I use the smallest variable which will do the work. Is it also dependent on a compiler and OS?
