I've created a list of strings and load a text file in it. once list is created, the program have to read it, do something and write results in a new text file. [CODE] ofstream f; f.open("filename.txt"); string key; list<string> text; static char ALPH[21] = {'A','B','C','D','E','F','G','H','I','L','M','N','O','P','Q','R','S','T','U','V','Z'}; int* index_t = new …

I wrote a program that creates a text file with some letters using ofstream. Now I would like to format the text so that the letters are written in groups of 5 and the rows are all the same length( i.e. DANIWEBFORUM becomes DANIW EBFOR UM). To do this the …

I have to write an application in which a text file is read and stored in a vector of strings [CODE]vector<string> text;[/CODE] After that I have to compare each character of text loaded from a file with an array of char with default content [CODE]char ARRAY[21] = {... ... ...}[/CODE] …

the program must read a text file, encrypt the content and then rewrite everything to a text file. compile ok, it crashes while running and still produces an empty output. how can I fix this? vigenere.h [CODE] #include <string> using namespace std; class Vigenere{ private: string key; string text; static …

I have to write an application which uses the Vigenere cipher with the Italian alphabet (only 21 characters, excluded J,K,W,X,Y). After a day of trying this is the code that I wrote [CODE] #include "vigenere.h" #include <string> using namespace std; Vigenere::Vigenere(string str){ key = str; key = StringToUpper(key); for(int cnt …

can someone tell me how this program works? I'm trying to learning C++ by reading some examples, and this one is one of them. [CODE]#include <iostream> #include <string> using namespace std; class Vigenere { public: string key; Vigenere(string key) { for(int i = 0; i < key.size(); ++i) { if(key[i] …
