    <p>This program is for adding two polynomials and printing the result.</p> <p>It just stores the multipliers in array and use the index az the power of parameter </p> <p>It does sum and subtract but when it comes to product it prints </p> <pre><code>0x0 0*x2 0*x3 ... </code></pre> <p>It's for basic C programming class and in three hours I should give it to master :-(</p> <p>It gets the multiplier in an array and calculates the result using some functions:</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; double a[50], b[50], c[101]; int dega, degb; SumArray (a, b) double a[], b[]; { extern int dega, degb; extern double c[]; int i, max = (dega &lt; degb ? degb : dega) + 1; for(i = 0; i &lt; max; i++) c[i] = a[i] + b[i]; } SubtractArray(a, b) double a[], b[]; { extern int dega, degb; extern double c[]; int i, max = (dega &lt; degb ? degb : dega) + 1; for (i = 0; i &lt; max; i++) c[i]=a[i]-b[i]; } ProductArray(a, b) double a[], b[]; { extern int dega, degb; extern double c[]; int i,j; double tempa, tempb; for(i = 0; i &lt; dega + 1; i++) for(j = 0; j &lt; degb + 1; j++) { tempa = a[i]; tempb = b[j]; c[i + j] = c[i + j] + (tempa * tempb); } } int main() { extern int dega, degb; extern double a[50], b[50], c[]; //stores the multipliers int i, operation; for(i = 0; i &lt; 50; i++) a[i] = b[i] = 0; for(i = 0; i &lt; 102; i++) c[i] = 0; printf("darjeye chand jomleee ha ra vared konid"); scanf("%d %d", &amp;dega, &amp;degb); printf("zarayebe chand jomlee aval ra vaerd konid"); for(i = 0; i &lt; dega + 1; i++) scanf("%d", &amp;a[i]); printf("zarayebe chand jomlee dovoom ra vaerd konid"); for(i = 0; i &lt; degb + 1; i++) scanf("%d", &amp;b[i]); printf("amaliyate morede nazartan ra vare konid baraye jame 0, tafrigh 1, zarb 2 ra vared konid"); scanf("%d", &amp;operation); switch(operation) { case 0: { SumArray(a,b); for (i = 0; i &lt; (dega &gt; degb ? dega : degb) + 1; i++) { printf(" %d*x", c[i]); printf("%d ", i); } break; } case 1: { SubtractArray(a,b); for (i = 0; i &lt; (dega &gt; degb ? dega : degb) + 1; i++) { printf(" %d*x", c[i]); printf("%d ", i); } break; } case 2: { ProductArray(a,b); for(i = 0; i &lt; (dega + degb + 1); i++) { printf("\%d*x", c[i]); printf("%d ", i); } break; } default: printf("amaliyate vared shode sahih nabud"); } system("PAUSE"); return 0; } </code></pre>

    1. COthis is some of the hardest to read code I have ever seen. if you clean it WAY up, I may come back and help, but otherwise no way.

    2. CO`scanf("%d",a[i]);` should be `scanf("%d",&a[i]);` and `scanf("%d",b[i]);` should be `scanf("%d",&b[i]);`

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
