How to access variable from class array object in function? - c++

Question

I am creating a Meet In The Middle cryptanalysis way to find the keys for a double caesar cipher.
I created a class Table where it holds each 26 possibilites of the cipher text along with the associated key used to get the cipher text.
Next I have a function findKeyPair that takes the second encrypted plain text and decrypts testing each key and searches the class table array object I made for matching cipher text. If there is a match the findKeyPair function sets a 2 element array keySolutions with the first element being the first key and the second element being the second key.
Then it should display the 2 keys used in the double caesar cipher.
The problem I am having is in the findKeyPair function. Whenever I use my getText() and getKey() function in findKeyPair the data returned seems blank. I have tried passing the point and by reference, but it is already an array so I don't understand where the problem is coming from.
This is my project so far, so if you want to run it you can:
`
#include <iostream>
#include <string>
#include <bits/stdc++.h>
using namespace std;
class Table {
private:
string cipherText;
int key_l;
public:
Table() : cipherText(""), key_l(0) {}
void putEntry(string plainText, int key);
string getText();
int getKey();
void printEntry();
};
string caesarCipher(string plainText, int key);
void findKeyPair(Table table[], string cipherText, int keySolutions[]);
int main()
{
Table table[26];
int keySolutions[2] = {0,0};
string knownPlainText = "Hello World";
int key1 = 4; int key2 = 13;
string cipherText = caesarCipher(knownPlainText, key1);
cipherText = caesarCipher(cipherText, key2);
findKeyPair(table, cipherText, keySolutions);
cout << "Key 1 = " << keySolutions[0] << "\nKey 2 = " << keySolutions[1] << endl;
return 0;
}
string caesarCipher(string plainText, int key)
{
string result = "";
for (int i = 0; i < plainText.length(); i++) {
if (plainText[i] == 32)
result += char(plainText[i]);
else if (isupper(plainText[i]))
result += char(int(plainText[i] + key - 65) % 26 + 65);
else
result += char(int(plainText[i] + key - 97) % 26 + 97);
}
return result;
}
void findKeyPair(Table table[], string cipherText, int keySolutions[])
{
string middleText = "";
string temp = "";
int key = 0;
for (int i = 0; i < 26; i++)
{
key = 26 - i;
middleText = caesarCipher(cipherText, key);
for (int j = 0; j < 26; j++)
{
temp = table[j].getText();
if (middleText.compare(temp) == 0)
{
keySolutions[0] = table[j].getKey();
keySolutions[1] = key;
}
}
}
}
void Table::putEntry(string plainText, int key)
{
cipherText = caesarCipher(plainText, key);
key_l = key;
}
string Table::getText()
{
return cipherText;
}
int Table::getKey()
{
return key_l;
}
void Table::printEntry()
{
cout << cipherText << endl;
}
`
I have tryed passing the Table table object array to the findKeyPair function by reference and the pointer. But no matter what the findKeyPair function can't access cipherText from the class Table when I use getText() function.
