title: adding only odd numbers
body: <p>So the question I'm trying to solve the user is supposed to enter any positive number. Then I'm trying to write a program that adds only the odd numbers up to the number the user enters and displays the total. So for example if the user enters 4 my program should add four odd numbers. 1 + 3 + 5 + 7 = 16. <br/> The only tools I have available are for statement, if, if/else if,while loop and println. <br/></p>
  
  <p>I can only figure out how to print out the odd numbers. I know I want to create a variable named total to store the value of adding up all the odd numbers but I don't know how that fits into the program. </p>
  
  <pre><code>import acm.program.*;
  
  public class AddingOddNumbers extends ConsoleProgram {
      public void run() {
          int n = readInt("enter a positive nunber: ");
          int total = 0;
          for (int i = 0; i &lt; n; i++) {
              if (n == 1) {
                  println(1);
              } else {
                  println((i * 2) + 1);
              }
          }
      }
  }
