wofstream automatically narrows wide characters - c++

Question

#include "stdafx.h"
#include <cstdlib>
#include <ctime>
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
using namespace std;
int main(int argc, char * argv[]) {
srand(time(NULL));
if (argc < 1) {
cout << "Too few arguments inserted.\nUSAGE: RKRIPT [InFile] [OutFile]" << endl;
return EXIT_FAILURE;
}
string InFile, OutFile;
InFile = argv[1];
OutFile = argv[2];
if (InFile.size() > FILENAME_MAX || OutFile.size() > FILENAME_MAX) {
cout << "Invalid filename lenght.\nFILENAME_MAX = " << FILENAME_MAX;
return EXIT_FAILURE;
}
wstring * Cont = new wstring;
if (Cont == nullptr) {
cout << "Memory allocation failed." << endl;
return EXIT_FAILURE;
}
wifstream i_f;
wchar_t temp;
i_f.open(InFile);
while (i_f.get(temp)) {
*Cont += temp;
}
i_f.close();
wofstream o_f;
o_f.open(OutFile);
long long int OutSize = 0;
for (long long int i = 0; i < Cont->size(); i++) {
do {
temp = wchar_t(rand() % WCHAR_MAX); //Keeps getting another value for temp until its sum with the current character doesn't exceed WCHAR_MAX.
} while (((long long int)temp + (long long int)Cont->at(i)) > WCHAR_MAX);
o_f << temp + Cont->at(i) << temp;
OutSize += 2;
}
o_f.close();
cout << "Done. Input file was " << InFile << "(" << Cont->size() << " Bytes)" << ". Output file is " << OutFile << "(" << OutSize << " Bytes)";
delete Cont;
return EXIT_SUCCESS;
}
This code is a simple "encrypter" that plays with altcodes to conceal characters. Though, when the application is done, the output file will be empty. The file output file I specified isn't anywhere at all. This application is meant to be run from shell. So, say I want to encrypt dummy.txt, I'll have to use this:RKRIPT dummy.txt out.txt.
At first I thought that I was using the stream incorrectly, leading to characters not to be printed out. But after changing
for (long long int i = 0; i < Cont->size(); i++) {
do {
temp = wchar_t(rand() % WCHAR_MAX); //Keeps getting another value for temp until its sum with the current character doesn't exceed WCHAR_MAX.
} while (((long long int)temp + (long long int)Cont->at(i)) > WCHAR_MAX);
o_f << temp + Cont->at(i) << temp;
OutSize += 2;
}
to this(notice the changes from WCHAR_MAX to CHAR_MAX)...
for (long long int i = 0; i < Cont->size(); i++) {
do {
temp = wchar_t(rand() % WCHAR_MAX); //Keeps getting another value for temp until its sum with the current character doesn't exceed CHAR_MAX.
} while (((long long int)temp + (long long int)Cont->at(i)) > CHAR_MAX);
o_f << temp + Cont->at(i) << temp;
OutSize += 2;
}
My output was just fine, because there were only narrow characters(ASCII) to write on my file. Though, I don't know how to fix this, how do I get my WIDE characters to be written onto a file using a WIDE stream? Thanks for any reply.
