Can we input negative numbers in the output windiw

I have a simple question.

Suppose we have to input a no. bu using "scanf()".

Can we input negative nos. in this case.

Code:

---

    main()
    {
          int  n;
          printf("enter the number");
          scanf("%d",&n);
      }

---

In this simple program can we input negative numbers in the output window.
If yes then how.

For negative numbers we will have to input "-" sign, how can we input it during the execution of the program.
