ET-575-Strings - Homework 1. String Manipulation. a) Input two string variables named firstn and lastn. b) Store your first name in the variable firstn and last name in lastn. c) Concatenate the values of firstn and lasnt with a space in the middle and store into a third variable fullname (such as "John Smith"). d) Print the variable fullname. e) Print the length of the variable fullname. f) Use functions to insert a middle initial into the fullname variable including spaces (such as "John H.
