Enter the number: 5
The value is: 1.6094379124341003

Few important points about this program:

1. To do mathematical operations, we need to import the math library.

2. The math library provides many log formulae, like loge, log10, log2 etc.

3. We find the natural log using the .log() method in the math library.
