so i need to encrypt a txt document using Caesar encryption. however i don't know how to open a txt and shift the keys into a new txt. the program has to ask the user for the number it should shift. Using arrays, if else. i also need to make a menu so i am using switch.
View 4 Replies View RelatedMy program attempts to encrypt a file using XOR operator. However, when I attempt to encrypt a file, it says "Error in reading file", (a printf function I set up if the program could not read the file, obviously). The problem is that I don't know what's causing this. Instead of encrypting the file, it just deletes all the characters in it, so I put in a fprintf to put place some text into the file. Here is the code:
Code:
#include<stdio.h>
#include<string.h>
int encryptd(FILE *);
int main(void)
{
FILE *fileptr;
int recode;
char fname[25];

I am writing a program in which the computer will read a txt file and encypt it. The encryption works fine, but the computer cannot read the file perfectly. If there's a newline, the scanning process stops. For example I have the following text in the txt file.
One two three four five
(newline) Six seven eight
The computer will stop reading after 'five'. I assume that is because I use fgets.
I'm having some trouble with my binary tree for school. It is a data structures class so we are working on learning how to make our own binary trees and encrypt messages. Everything so far is working, except for my delete node function. I'm trying to do it recursively. Parts of my code.

I am trying to encrypt a char Array with binary data.
I think I understand the basic of Encryption / Decryption but I fail to see how to implement something.
I am trying to have a "key" that needs entered so the data can become readable executable. The program I am encrypting is a small console window with a message with the text "A secret message from your friend" (Not that it matters).
I have the binary data witch I can copy and what not. But how go about Encryption and then decrypt it and not destroying the data.
I need to create a function using rot to encrypt certain strings the function begins like this
#include "encrypt.h"
std::string encrypt (std::string text, int rot) {

return NULL;

dont need to write the string encrypted and dont need to crate a decrypt function.
I'd wrote a program to encrypt a message within a bmp file using my own structs and all for everything (yes, call me a ........head) The program works but for some weird ........ing reason I was forced to subtract 2 bytes from the header size to get the correct value. I've narrowed down the issue to my BmpFileHeader struct.
Here's a short program that demonstrates the issue:
Code:
#include <stdio.h>
#include <stdlib.h>
#define BYTE unsigned char
#define WORD unsigned short
#define DWORD unsigned long
#define LONG signed int
[Code] .....
Tried with both gcc and TinyCC and got the same result so it doesent seem to be a compiler bug. Microsoft's structures though are giving the correct size, even though they have the exact same definition.
Microsoft's defines:
Code:
// windef.h
typedef unsigned long DWORD;
typedef unsigned char BYTE;
typedef unsigned short WORD;

I have got to create a program that will gather input from the user and then encrypt & decrypt those characters.
I'm not very confident at coding so I'm sure many parts of my code are written poorly and not following the best practice so I have written a simple version of an algorithm where the program simply adds/subtracts a value of 2 to/from the ASCII values but I have discovered the use of the rand() and srand functions but I'm unsure how to go about using them within both my encrypt and decrypt function as a single value (static variable?).
Here is my code in its entirety at the moment.
#include <iostream >
#include <iomanip>
#include <cstdlib>
#include <ctime>
#include <string>
#include <cstring>
#include <fstream>
using namespace std;
char getMenuSelection (char m);
void encrypt (char key[]);
void decrypt (char code[]);
[code]....
This code currently doesn't execute due to ' undefined reference to 'encrypt(char*) '
Question
I am asking how to generate the random number and incorporate this into my encrypt and decrypt functions.
1. Would the use of a static or global variable make this work as is?
2. Would I need to create separate class files for both functions?

I have been here for almost 3 months looking for answers in my C++ problems.here's some type of code for this.
cout << "Enter value of x: " << endl; //Let's say 5.
cin >> x;
cout << "Enter equation: "; //Let's say x+1
cin >> equation;
Then the program analyzes that this character "x" has an initial value of 5.I already have the parser for the equation functions (+,-,*,/)This is the only thing lacking. Is there some type of function that i missed?
Program works perfectly fine. I input in the length, width and height. But i want it to display those values for every individual prism when i output... along with the area and volume which i already have. Since i made a vector i won't let me cout it normally.

I need to allow the user to input an integer of any length and print out the word of each number in the integer. So the user would enter "324562" and then the output would be "three two four five six two". I'm struggling to understand the best way to do it in C. I know I need a loop that goes through the int but I don't know how to do it

I've been working on this program and I have it all pretty much down, but I just need one thing that I can't, for the life of me, think of! I need to find the reciprocal of a number that the user inputted (ex: if user input was 2 output would be 0.5 or if input was .6, out put would be 1.6 repeating). If theres a simple way, I can't think of it.

I've written a program which takes a character string and then prints each character vertically so that for instance the string 123 can be written as
1
2
3
no what i need is for all the numbers from zero to the inputted number to print the numbers digits vertically but each number to be printed horizontally so that for instance an input of 11 prints
1 2 3 4 5 6 7 8 9 1 1
0 1
i've made it so that i can print all numbers up to the inputted number vertically; however, i am stuck with a method for making each number print horizontally as described above.

The program is supposed to have a method called Hitscore that adds a score between 0 and 1000 inputted by the user to the total score and increases level by one and print the score to the screen and which level they last completed after each entry . Have the user continue inputting scores to the program until the gamer has finished all 10 levels. After 10 levels, use a method you create called PassScore to have the program compare the score to avgscore (5000). If the score is less than avgscore, have the code respond "You are not angry at all. " if it is above avgscore, then have it respond "You seem quite angry, calm down. " and if it is exactly 5000, have it respond "Average, just average. "
