    copied!<p>I have been coding a blackjack game that is almost done it's first stage of development. I am almost done, the only problem is that the random numbers that are generated in this part:</p> <pre><code>if(x.hit == 1) { if (x.userShowCardThree == 0) { x.userShowCardThree = 1 + (rand()%11); int dealerHit1 = x.userShowCardThree; x.userTotal += dealerHit1; x.cardCount++; } else { if (x.userShowCardFour == 0) { x.userShowCardFour = 1 + (rand()%11); int dealerHit2 = x.userShowCardFour; x.userTotal += dealerHit2; x.cardCount++; } else { if (x.userShowCardFive ==0) { x.userShowCardFive = 1 + (rand()%11); int dealerHit3 = x.userShowCardFive; x.userTotal += dealerHit3; x.cardCount++; } } } </code></pre> <p>is not the same as the numbers generated in the final part:</p> <pre><code> cout &lt;&lt; "You had a total of: " &lt;&lt; x.userTotal &lt;&lt; endl; </code></pre> <p>as i keep getting different numbers. I will paste my entire code below.</p> <pre><code>#include &lt;iostream&gt; #include &lt;ctime&gt; #include &lt;cstdlib&gt; #include &lt;cstring&gt; using namespace std; void setRand() { srand(time(0)); } class Game { public: int userCards[11] = {1,2,3,4,5,6,7,8,9,10,11}; int dealerCards[11] = {1,2,3,4,5,6,7,8,9,10,11}; int userShowCardOne = userCards[1 + (rand()%11)]; int userShowCardTwo = userCards[1 + (rand()%11)]; int dealerShowCard = dealerCards[1 + (rand()%11)]; int dealerHiddenCard = dealerCards[1 + (rand()%11)]; int userShowCards[5] = {userShowCardOne, userShowCardTwo, userShowCardThree, userShowCardFour, userShowCardFive}; int userShowCardThree = 0; int userShowCardFour = 0; int userShowCardFive = 0; int fresh = 1; int beginningInput; int hit = 1; int dealerTotal = dealerShowCard + dealerHiddenCard; int userTotal = userShowCardOne + userShowCardTwo; int cardCount = 2; int runGame = 1; private: }; // int a = 1 + rand()%11; /*int b = 1 + rand()%11; int c = 1 + rand()%11; int d = 1 + rand()%11; int e = 1 + rand()%11; int f = 1 + rand()%11; int g = 1 + rand()%11; int h = 1 + rand()%11; */ int startGame(); int main() { srand(time(0)); Game x; cout &lt;&lt; "Welcome to BlackJack 1.0.0" &lt;&lt; endl; cout &lt;&lt; "Press: " &lt;&lt;endl; cout &lt;&lt; "1 ----- New Game" &lt;&lt; endl; cout &lt;&lt; "2 ----- Help" &lt;&lt; endl; cin &gt;&gt; x.beginningInput; if(x.beginningInput == 1){ startGame(); cout &lt;&lt; "The dealer had: " &lt;&lt; endl; cout &lt;&lt; x.dealerHiddenCard &lt;&lt; endl; cout &lt;&lt; x.dealerShowCard &lt;&lt; endl; while(x.dealerTotal &lt;= 16) { cout &lt;&lt; "The dealer has decided to hit" &lt;&lt; endl; int dealerHit = 1 + (rand()%11); cout &lt;&lt; "The dealer has gotten " &lt;&lt; dealerHit &lt;&lt; endl; x.dealerTotal += dealerHit; } cout &lt;&lt; "The dealer has decided to stay" &lt;&lt; endl; cout &lt;&lt; "The dealer had a total of " &lt;&lt; x.dealerTotal &lt;&lt; endl; cout &lt;&lt; "You had a total of: " &lt;&lt; x.userTotal &lt;&lt; endl; if (x.dealerTotal &gt; 21 &amp;&amp; x.userTotal &lt;= 21) { cout &lt;&lt; "The dealer busted.
