scanf always prints entered number

Just started learning C and I have a problem with the scanf function. Every time I enter a number in the console, it will be printed right under the input. The program still works, but it is a little bit annoying.
(I am using CLion from JetBrains)

int main()

{

   int x;

   printf("Number: ");

   scanf("%d", &x);

   printf("Your number is %d!", x);

}

This is the output:

Number:15 15 Your number is 15! Process finished with exit code 0

The code itself does not evoke such behavior. What environment are you using?

"scanf always prints entered number" - No, scanf doesn't print anything. I am not familiar with JetBrains, but where you enter the number and press "Enter" your stdin should contain "15n", scanf read and stores 15 in x and leaves the 'n' unread in stdin. Hard to see how that cause the issue.

I tried this code with visual studio2017 c++14 and I haven't receive same response with you every thing works how its suppose to work with. So scanf doesn't print anything. Change your compiler

It is an issue in clion (Why is CLion printing back inputs from standard input?). Currently unresolved. This problem exist for C and C++.
This bug resides for four years. I definitely advice you to change your compiler if you are not bound this for a particular reason.
