According to your code,
The variable `var` is not assigned in any value, so it contains an unpredictable value.
For random number, use the `rand()` function..

Answer 2

The code you provided doesn’t generate a random number. Instead, it declares an integer variable and prints its value. Since var is not initialized, its value is undefined and can be any garbage value.
