This program takes basic information such as first name, last name, birth year, and birth month to calculate the current age of a user. 
It then prints a personalized greeting message displaying the user's name and age. 
This simple program demonstrates basic variable assignments, arithmetic operations, and conditional statements in Python.

Explanation:
*User Information: * first_name and last_name store the user's name. current_year and current_month store the current year and month. dob and birth_month store the user's year and month of birth.

* Age Calculation:* The program calculates the initial age by subtracting the birth year from the current year. If the current month is greater than the birth month, the calculated age remains the same. If the current month is less than or equal to the birth month, the age is decremented by one year to account for the upcoming birthday.

* Output Greeting:* The program prints a personalized message using formatted strings, showing the user's full name and age.

* User Input:* The program takes in user input to calculate user's age.
