    <p>I am making this program for an assignment at school, however we need to get the highest number of rolls it takes to obtain a Yahtzee and the lowest number of rolls it takes to get a Yahtzee. Then we need to find the average number of rolls. At the moment I am kind of confused on where I went wrong with determining the highest and lowest number of rolls to obtain a Yahtzee. Can anyone help me out, I would greatly appreciate it. The program runs until 100 natural Yahtzees are obtained.</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; #include &lt;time.h&gt; #include &lt;limits.h&gt; int main( void ) { // MARKS THE BEGINNING OF THE main( ) BLOCK OF STATEMENTS int die1 = 0 , die2 = 0 , die3 = 0 , die4 = 0, die5 = 0 , roll = 0 ; int lownr = INT_MAX , highnr = 0 , yahtzee = 0 , averagenr; int roll_total = 0 ; srandom ( (unsigned) time (NULL) ) ; printf( "\nWelcome User, this program demonstrates the " ) ; printf( "number of rolls it takes to obtain" ) ; printf( "\na natural Yahtzee.\n" ) ; die1 = random ( ) % 6 + 1; die2 = random ( ) % 6 + 1; die3 = random ( ) % 6 + 1; die4 = random ( ) % 6 + 1; die5 = random ( ) % 6 + 1; printf( "\nYou rolled: %d, %d, %d, %d, %d.\n\n" , die1 , die2 , die3 , die4 , die5 ) ; while (yahtzee &lt; 100) { ++roll; ++roll_total; die1 = random ( ) % 6 + 1; die2 = random ( ) % 6 + 1; die3 = random ( ) % 6 + 1; die4 = random ( ) % 6 + 1; die5 = random ( ) % 6 + 1; if ((die1==die2) &amp;&amp; (die2==die3) &amp;&amp; (die3==die4) &amp;&amp; (die4==die5)) { yahtzee = yahtzee +1; /* If you have yahtzee, compare roll with previous values of highnr/lownr */ if (roll&gt;highnr) highnr = roll; if (roll&lt;lownr) lownr = roll; /* Reset the roll counter, for next yahtzee */ roll = 0; } } averagenr = roll_total / yahtzee ; printf("\n The total number of yahtzees you rolled is: %d.",yahtzee); printf("\n The total number of times you rolled is: %d.",roll_total); printf("\n The highest number of rolls to get a yahtzee is: %d",highnr); printf("\n The lowest number of rolls to get a yahtzee is: %d", lownr); printf("\n The average number of rolls to obtain a yahtzee is: %d", averagenr); printf ( "\n\n Thank you for using this program. " ) ; printf ( "GoodBye.\n\n " ) ; return ( 0 ) ; } </code></pre> <p>Sample Output</p> <pre><code>Welcome User, this program demonstrates the number of rolls it takes to obtain a natural Yahtzee. You rolled: 5, 5, 3, 2, 1. The total number of yahtzees you rolled is: 100. The total number of times you rolled is: 116704. The highest number of rolls to get a yahtzee is: 5284 The lowest number of rolls to get a yahtzee is: 18 The average number of rolls to obtain a yahtzee is: 1167 Thank you for using this program. GoodBye. </code></pre> <p><strong>SOLVED</strong></p>

    3. COYou may need to start your roll counter at `1`. Might want to take a second look at your other variables too. IE `highnr` can start at zero, but `lownr` cannot.

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.
