Explanation:

Here, we set the integer data type main method "main()" and inside it:

we set integer type array variable with index value 100.
we set two integer type variable "value" and "i" initialize value 0.
we set the do-while loop in which we get the input from the user and and append in the array and pass condition if the value is greater then equal to 0.
Finally, set for loop and print the elements of an array.
