    Additionally... This is a good opportunity for you to start familiarizing yourself with [using a debugger](https://stackoverflow.com/q/25385173/328193). When you step through the code in a debugger, which operation first produces an unexpected result? What were the values used in that operation? What was the result? What result was expected? Why? – David Jul 19 '23 at 14:36
  • `i%num == 0` for the numbers in the range of `[2, num]` will only ever be true once, when `i == num`. I'd also encourage using brackets/braces a little more liberally. – Rogue Jul 19 '23 at 14:37
  • Thank you so much for the enlightenment as a beginner I am yet to become familiar with the platform. – HRISHIKESH DEY Jul 19 '23 at 14:58

Change the if condition or statement from if(i%num == 0) to if(num%i == 0). It will lead to correct output. In our case input is number 10 it is divisible by number 2 and number 5. Then the program will print 10 is not an prime number.
