A program has been written in C# to display all the odd integers between 1 and the largest odd number smaller than an integer entered by the user - AQA - GCSE Computer Science - Question 15 - 2021 - Paper 1

To ensure the program handles odd integers correctly, we need to first check if the entered number is odd and then adjust the starting point of the odd integers accordingly.

1. Begin with the existing loop and add a condition to check if the number is odd:

   if (number % 2 == 0) {
       number -= 1; // Make the number odd if it's even
   }
   

2. Introduce a check at the beginning of the while loop to ensure it can handle cases like negative odd integers. Adjust the loop to start from 1:

   while (odd <= number) {
   

This way, the program will correctly display odd integers for both positive and negative inputs.
