The provided C code is a program that takes a list of numbers as input from the user and removes any duplicate numbers from the list. It stores the unique numbers in an array called listOfNumber.

Here's a brief explanation of how the program works:

1. The program initializes an array listOfNumber of size 100 to store the unique numbers. It also initializes variables index (to keep track of the current index in the listOfNumber array), number (to read the user's input number), and found (to check if the number is already present in the array).

2. The program uses a while loop with scanf to read numbers from the user continuously until the user stops entering numbers (by pressing Ctrl+Z on Windows or Ctrl+D on Unix-based systems).

3. For each number entered by the user, the program sets found to 1 (indicating the number is not found in the array yet) and iterates over the existing elements in the listOfNumber array.

4. If the number is already present in the listOfNumber array, the program sets found to 0 (indicating the number is a duplicate).

5. If the number is not a duplicate (i.e., found is still 1), the program stores the number in the listOfNumber array at the current index (index) and increments the index.

6. After the user stops entering numbers, the program prints the final list of unique numbers stored in the listOfNumber array.

7. The program then terminates by returning 0.

 

Example Input and Output:

Input: 1 2 3 2 4 5 1 6 7 5 8 9 10 (Enter Ctrl+D or Ctrl+Z to stop entering numbers)

Output: [ 1 2 3 4 5 6 7 8 9 10 ]
 

The program removes the duplicates (2, 1, and 5) and prints the final list of unique numbers in ascending order.
