    copied!<p>I am trying to make a filter that prints on the screen only the data I want. Here's what I am talking about:</p> <pre><code>Cost* FilterSum(Controller* ctrl, int n) { int i; DynamicVector* CostList=getAll(ctrl-&gt;repo); for(i=0;i&lt;getLen(CostList);i++) { Cost* c=getElementAtPosition(CostList,i); //returns the element on one position if((c-&gt;sum)&lt;n) { return c; //if the element(Cost in my case) has the sum&lt;20 return it } } return 0; } </code></pre> <p>So, I have Dynamic Array with Costs as elements. If the sum of the cost is less than n(n is given from the keyboard) I want to print on the screen only those costs. :) This are the print functions in the console:</p> <pre><code>void PrintCost(Cost* c) //this function prints one cost { printf("\nID: %d\n", getID(c)); printf("Day: %s\n", getDay(c)); printf("Type: %s\n", getType(c)); printf("Sum: %d\n\n", getSum(c)); } void PrintCosts(Console* console) //this one prints all the costs in the list { DynamicVector* CostList=getAllCosts(console-&gt;ctrl); if (getLen(CostList)) { int i; for(i=0;i&lt;getLen(CostList);i++) { Cost *c=(Cost*)getElementAtPosition(CostList,i); PrintCost(c); } } else printf("No cost in the list!"); } </code></pre> <p>And here is the call function from controller in the console:</p> <pre><code>void FilterCostsBySum(Console* console) { int n; printf("See the costs that have the sum less than: "); scanf("%d",&amp;n); Cost* c = FilterSum(console-&gt;ctrl,n); PrintCost(c); } </code></pre> <p>Now, here comes the problem. If I have Monday with sum=10, Friday with sum=20 and Saturday with sum=40 and I want to print only those days with sum&lt;30, it just prints Monday and that's it, it doesn't print Friday too. Where am I doing wrong? In the FilterSum function in the controller where I return the c? I tried everything and it didn't work at all... maybe you can help me! :)</p>
