    copied!<p>I'm in stuck with one issue. Here's my code. I have <code>class Card</code> and <code>class deckOfCards</code>. My problem is in functions <code>straight</code> and <code>sortFunc</code>. I want to sort my vector that I created in <code>main</code> called <code>fiveHand</code>. I saw a lot of examples but in my case I can't understand how to do this correctly. </p> <p>I have errors like <code>i</code> and <code>j</code> were not declared:</p> <pre><code>#include &lt;iostream&gt; using namespace std; class Card { private: int m_suit; int m_face; public: Card(int face, int suit); static string suits[]; static string faces[]; static string toString(string s_face, string s_suit); int getFace(); void setFace(int face); int getSuit(); void setSuit(int suit); }; Card::Card(int face, int suit) { m_face = face; m_suit = suit; } string Card::faces[] = {"Ace", "Deuce", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"}; string Card::suits[] = {"hearts", "diamonds", "clubs", "spades"}; int Card::getFace(){return m_face;} void Card::setFace(int face){m_face = face;} int Card::getSuit(){return m_suit;} void Card::setSuit(int suit){m_suit = suit;} string Card::toString(string s_face, string s_suit) { string card = s_face + "\tof\t " + s_suit; return card; } #include &lt;iostream&gt; // cout #include &lt;algorithm&gt; // random_shuffle #include &lt;vector&gt; // vector #include &lt;ctime&gt; // time #include &lt;cstdlib&gt; #include "Card.h" using namespace std; class deckOfCards { private: vector&lt;Card&gt; deck; public: deckOfCards(); static int count; static int next; vector&lt;Card&gt;&amp; getDeck() {return deck;} void shuffle(vector&lt;Card&gt;&amp; deck); Card dealCard(); bool moreCards(); void pairs(vector&lt;Card&gt;&amp; fiveHand); void threeOfKind(vector&lt;Card&gt;&amp; fiveHand); void fourOfKind(vector&lt;Card&gt;&amp; fiveHand); void flush(vector&lt;Card&gt;&amp; fiveHand); void straight(vector&lt;Card&gt;&amp; fiveHand); bool sortFunc(vector&lt;Card&gt;&amp; fiveHand[i], vector&lt;Card&gt;&amp; fiveHand[j]); }; int deckOfCards::count = 0; int deckOfCards::next = 0; deckOfCards::deckOfCards() { const int FACES = 13; const int SUITS = 4; for (int suit = 0; suit &lt; SUITS; suit++) { for (int face = 0; face &lt; FACES; face++) { Card card = Card(face, suit); //card created and initialized deck.push_back(card); } } } void deckOfCards::shuffle(vector&lt;Card&gt;&amp; deck) { srand(static_cast&lt;unsigned int&gt;(time(0))); random_shuffle(deck.begin(), deck.end()); } Card deckOfCards::dealCard() { Card nextCard = deck[next]; next++; return nextCard; } bool deckOfCards::moreCards() { const int FIVE_CARD = 5; if (count &lt; FIVE_CARD) { count++; return true; } else return false; } void deckOfCards::pairs(vector&lt;Card&gt;&amp; fiveHand) { int pair = 0; const int MAX_CARDS = 5; for (int i = 0; i &lt; MAX_CARDS; i++) { int j = i+1; for (j; j &lt; MAX_CARDS; j++) { if (fiveHand[i].getFace() == fiveHand[j].getFace()) pair++; } } if (pair == 1) { cout &lt;&lt; "You have one pair!" &lt;&lt; endl; } else if (pair == 2) { cout &lt;&lt; "You have two pairs!" &lt;&lt; endl; } } void deckOfCards::threeOfKind(vector&lt;Card&gt;&amp; fiveHand) { if (((fiveHand[0].getFace() == fiveHand[1].getFace())&amp;&amp;(fiveHand[1].getFace() == fiveHand[2].getFace())) ||((fiveHand[1].getFace() == fiveHand[2].getFace())&amp;&amp;(fiveHand[2].getFace() == fiveHand[3].getFace())) ||((fiveHand[2].getFace() == fiveHand[3].getFace())&amp;&amp;(fiveHand[3].getFace() == fiveHand[4].getFace()))) { cout &lt;&lt; "Your hand contains three cards of the same faces!" &lt;&lt; endl; } } void deckOfCards::fourOfKind(vector&lt;Card&gt;&amp; fiveHand) { if (((fiveHand[0].getFace() == fiveHand[1].getFace()) &amp;&amp;(fiveHand[1].getFace()== fiveHand[2].getFace()) &amp;&amp;(fiveHand[2].getFace()== fiveHand[3].getFace())) ||((fiveHand[1].getFace() == fiveHand[2].getFace()) &amp;&amp;(fiveHand[2].getFace() == fiveHand[3].getFace()) &amp;&amp;(fiveHand[3].getFace() == fiveHand[4].getFace()))) { cout &lt;&lt; "Your hand contains four cards of the same faces!" &lt;&lt; endl; } } void deckOfCards::flush(vector&lt;Card&gt;&amp; fiveHand) { if ((fiveHand[0].getSuit() == fiveHand[1].getSuit()) &amp;&amp;(fiveHand[1].getSuit() == fiveHand[2].getSuit()) &amp;&amp;(fiveHand[2].getSuit() == fiveHand[3].getSuit()) &amp;&amp;(fiveHand[3].getSuit() == fiveHand[4].getSuit())) { cout &lt;&lt; "Congradulations!!!
