Write a program in C programming language Please take an integer n from the user. This integer must satisfy the following constraint, 0 < n 100 Then, you should print a staircase of size n using @ symbols and spaces. If the constraint is not satisfied, you have to print an error to the screen. Here is an example: Input: n = 3 Output: Line 1 @ Line 2 @@ Line 3 @@@

Note that, the staircase is right-aligned, composed of symbols @ and spaces, and has a height and width of n = 3.
