 In this example, we first create a `const` variable, `original_value`. Then we use `const_cast` to remove the constness of the variable and assign it to a non-const pointer, `non_const_value_ptr`. The `modifyVariable` function takes an `int*` as an argument and modifies the value pointed to by the pointer, which would not have been possible if we passed the original `const int` directly. Finally, we print the `original_value` and the `*non_const_value_ptr`, which shows that the value has been modified using `const_cast`.

 # DATEDIF
 
-The `DATEDIF` function is an incredibly valuable tool for a Data Analyst in Excel or Google Sheets, by providing the ability to calculate the difference between two dates. This function takes in three parameters: start date, end date and the type of difference required (measured in years, months, days, etc.). In Data Analysis, particularly when dealing with time-series data or when you need to uncover trends over specific periods, the `DATEDIF` function is a necessary asset. Recognizing its functionality will enable a data analyst to manipulate or shape data progressively and efficiently.
