    <p>I'm trying to write a a program that lets the user generate anywhere from 1-75 Fibonacci numbers, print them, and then add all of those values together to get to over all sum. I had no problem generating the numbers and printing them, but for some reason I'm having a <em>lot</em> more trouble with the sum function. For some reason it only returns 0...and after staring at this for as many hours as I have I'm at a loss. Any and all help would be greatly appreciated. My code is below:</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; //function to calculate fibonacci number 1-75 (user specified) int fibonacci(int * array, int size) { int i; unsigned long long int Fibonacci[size]; //generating the array to save the Fibonacci values Fibonacci[0] = 0; //by definition Fibonacci[1] = 1; //by definition for (i = 2; i &lt; size; i++) { Fibonacci[i] = Fibonacci[i-2] + Fibonacci[i-1]; //equation to calculate the numbers } for (i = 0; i &lt; size; i++) { printf("%llu\t", Fibonacci[i]); //printing out the numbers } printf("\n"); return size; } int fibonacciSum(int * array, int size) { int i; int sum = 0; for (i = 0; i &lt; size; i++) { sum += array[i]; } return sum; } int main(void) { int size; printf("How many Fibonacci numbers do you want to generate (between 1 and 75)?\n"); scanf("%i", &amp;size); int * FibonacciNumbers = (int*) calloc(size,sizeof(int)); if (size &lt; 1 || size &gt; 75) { printf("Bad number!"); return 1; } fibonacci(FibonacciNumbers, size); printf("The sum of the Fibonacci numbers is: %d\n", fibonacciSum(FibonacciNumbers, size)); 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.
