    <p>For my computer programming class, I decided to make a program that generates a random coin flip and keeps track of the longest consecutive streak for both heads and tails. I have searched the internet and found no answer. The count is not displaying right. Even just a hint would be great! Thanks, Justin</p> <pre><code>int main(){ int number_of_flips; int coin_flip; int previous_flip = 2; int head_count = 0; int tail_count = 0; int highest_head = 0; int highest_tail = 0; srand(time(NULL)); cout &lt;&lt; "Enter the number of coin flips:" &lt;&lt; endl; cin &gt;&gt; number_of_flips; system("cls"); for(int i = 0; i &lt; number_of_flips; i++){ coin_flip = rand() % 2; if(coin_flip == 0){ cout &lt;&lt; "Heads" &lt;&lt; endl; if(coin_flip == previous_flip){ head_count = head_count + 1; } else{ if(head_count &gt; highest_head){ highest_head = head_count; } head_count = 0; } } if(coin_flip == 1){ cout &lt;&lt; "Tails" &lt;&lt; endl; if(coin_flip == previous_flip){ tail_count = tail_count + 1; } else{ if(tail_count &gt; highest_tail){ highest_tail = tail_count; } tail_count = 0; } } previous_flip = coin_flip; } cout &lt;&lt; "The longest run of heads is " &lt;&lt; highest_head &lt;&lt; endl; cout &lt;&lt; "The longest run of tails is " &lt;&lt; highest_tail &lt;&lt; endl; system("pause"); return 0; } </code></pre> <p>Here is an example of the output:</p> <pre><code>Tails Tails Tails Heads Heads Tails Tails Tails Tails Heads The longest run of heads is 1 The longest run of tails is 2 </code></pre> <p>As a reference, here is my final code that I believe works now:</p> <pre><code>int main(){ int number_of_flips; int coin_flip; int previous_flip = 2; int head_count = 0; int tail_count = 0; int highest_head = 0; int highest_tail = 0; srand(time(NULL)); cout &lt;&lt; "Enter the number of coin flips:" &lt;&lt; endl; cin &gt;&gt; number_of_flips; system("cls"); for(int i = 0; i &lt; number_of_flips; i++){ coin_flip = rand() % 2; if(coin_flip == 0){ cout &lt;&lt; "Heads" &lt;&lt; endl; if(coin_flip == previous_flip){ head_count = head_count + 1; } else{ if(head_count &gt; highest_head){ highest_head = head_count; } head_count = 1; } } if(coin_flip == 1){ cout &lt;&lt; "Tails" &lt;&lt; endl; if(coin_flip == previous_flip){ tail_count = tail_count + 1; } else{ if(tail_count &gt; highest_tail){ highest_tail = tail_count; } tail_count = 1; } } previous_flip = coin_flip; } if(head_count &gt; highest_head){ highest_head = head_count; } if(tail_count &gt; highest_tail){ highest_tail = tail_count; } cout &lt;&lt; "The longest run of heads is " &lt;&lt; highest_head &lt;&lt; endl; cout &lt;&lt; "The longest run of tails is " &lt;&lt; highest_tail &lt;&lt; endl; system("pause"); return 0; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
