I've always found it simpler to allocate a one-dimensional array, and then calculating the row and column manually, it's an easy approach, and it works.

First thanks to add code tags to your post.
Second, (and I know this may sound harsh): your code is the ideal example of how one shouldn't program it, but no fear, we're here to help you and give...

Ouch, my eyes!!

Please use BB Code and Inlinecode tags (http://www.daniweb.com/forums/announcement8-3.html)
What's the deal with void main()?...

Since cake is a character array, the following instruction will allow an array overflow (in case there are more than 80 characters entered):
cin >> cake;,
you can prevent this by for example using...

Post down your code please.

This won't fix your problem, but it will fix a memory leak:
if you write this in your code: char *cool=new char[20];//the name pointer then at some point in future your program doesn't need the...

Could you provide us with the file you tried to encrypt/decrypt using your program?

Oh yes, and how do you explain the several minutes difference between all those posts then?
The post above this one (if not already removed by a moderator) is just the evidence that it hasn't...

Okay, I really have enough of your double postings in your thread:

a) you won't get help faster by doing this
b) you just make your own thread unreadable
c) you waste your time, use that time to...

if(currentChar<(char)'0' || currentChar>(char)'9'){
cout << "Invalid Pin" << endl;
}
Explicitly casting to a char isn't even needed here, the following code is equivalent:
if(currentChar<'0'...

I guess you mean all characters other than 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 when you say: any non-numeric character.

Why not just get your number like this:

int num;
cout << "Enter a number: ";
...

How I would go trough the process of designing such a program:
Create a simple menu, which will allow the user to choose whether he wants to encrypt or decrypt. (you've done this)

Create two...

Is that the only reason you want to undertake all the work to write an encryption program?
Even if TrueCrypt is available for Linux as well ?

As far as I know I only used cout, which you also did (you even mixed C with C++ I/O (which is also OOP), so I don't see where the problem is :)

Do you want to rewrite the whole program in C or...

First of all I want you to NOT PM me with your questions to do it for you, it won't work, I'm a free person and I'm free to do what I want, and not to do what I don't want (let that be clear).
What...

Well, you know the text editor? I meant: the program where you write your code in, launch that program, open the file containing the code of your program, copy that code, and paste it in a new post...

To the OP:
No offense, but I can't trust the code you posted down.
Wait, let me explain, I came across a line which looked quite strange to me, and which will never let me compile this program:...

Could you maybe explain us first what the goal of the program you posted is? (I mean: what output do you expect, etc.)

To answer the question in your signature:
Start a new thread about the bug...

Your encryption algorithm should work fine, I tested it using the following code:
#include <iostream>
#include <climits>

int main()
{
int encrypt;
int decrypt;

for(int...

I tested the program you posted, encrypting and decrypting is working fine, only one major remark I have is that the program hangs at the end of the encryption/decryption progress.

This:
...

Can you show us the program with the changes you've made?

I guess that it would be the best to just use Google to find yourself some examples, remember: Google is your friend!
I'm convinced there are plenty of examples on bitwise operators floating around...

How do you mean: the bit cannot be toggled? By my means you can always toggle a bit: in case the bit is one, you toggle it, and it becomes a zero; in case the bit is zero, you toggle it, and it...

Yep, if you use bitwise AND, then only if the two corresponding bits are one, then the bit in the outcome is also one, otherwise it is always zero (you can derive this rule from that truth table).
...

>are they trying to turn off the last bit?
Did you maybe skip the truth table for AND-operations at the bottom of one of my previous posts?
Should I repost it again, or just give you a link...

I don't quite get what you mean by this (even your example doesn't seem to help me understand what you mean).

Nope, most likely some decimal value will be displayed on your screen.

Could you...

Yup! To understand how it works, you have to 'think binary' :)
Yes, as long as you choose a correct mask.
Well, say you want to turn off bit 3 of a certain value, then you first need to choose a...

Let me explain this to you:

if ( b & 0x10 )
cout << "Bit four is set" << endl;
else
cout << "Bit four is clear" << endl;
To start off: 0x10 is the hexadecimal number for 16 (in...

Not always necessary, but in this case it seems most appropriate.
Just take the way which is easiest for you, and in most cases, it's directly inputting the value.
(If the value is in another base...

Quick fix for anyone who's reading this thread: when you read one of my previous posts, replace every 16 you encounter with a 15 :)

I guess you misunderstood my previous post, wait let me explain it again:
As you know, C++ is a programming language, to make it a bit more complicated: C++ offers support for variables.
When you...

Nope, a value in an integer variable is technically stored as a binary value.
For example: whether you assign 16 (in decimal), or 0xF (in hexadecimal) to an integer variable, the integer variable...

0xF7 is a hexadecimal number, it is the same as 247 in decimal.

But in C/C++ you don't have to convert it or something, you just set your mask to 0xF7.

You'll probably say: How do I do that?...

Short answer: take a value where all bits (except the third) are 1 (the third needs to be 0), this is your mask.
Then you (bitwise) AND it together with the value where you want to set the third bit...

Having a hard time using Google?
My first advice before starting a new thread is: STFW first!

Well, hard-coding the whole alphabet in your program is possible, but there's another way, without needing to hard-code the whole alphabet in your program, let me describe it:
The above sample run...

I'm sure you can, when you do some effort:
http://www.daniweb.com/forums/announcement8-2.html

Sure, don't take this wrong but I would like to see first that you've at least tried to solve it.

Remove this line from your code (if you don't make use of the Allegro library):
#include <allegro.h>

Or if you're using Allegro:
If I'm not wrong each Allegro program looks like:

#include...

Well, try this one:

wordRecord test; // (1)
sc.printDict(test);

(1): You can put struct at the beginning of this line, but this isn't obligated in C++.

An addition for the OP:
Also ensure that the variable newSize is of type size_t.
Strings don't have negative lengths, so using int isn't the best option here (because it's signed, this means that...
