Write a program that creates a login name for a user, given the user's first name, last name, and a four$-$digit integer as input. Output the login name, which is made up of the first six letters of the first name, followed by the first letter of the last name, an underscore $(\_),$ and then the last digit of the number $($use the $\%$ operator$).$ If the first name has less than six letters, then use all letters of the first name.

Ex: If the input is:

Michael Jordan $1991$

the output is:

Your login name: MichaeJ$\_1$

Ex: If the input is:

Nicole Smith $2024$

the output is:

Your login name: NicoleS$\_4$
