In programming; when two or more strings are concatenated by a concatenating operator, the result is always a new string.
From the question, we have that
str1 = "Good
str2 = "Evening"
Let's assume that + is the concatenating operator;
str1 + str2 = "Good" + "Evening" = "GoodEvening"
The result of concatenating str1 and str2 is a new string "GoodEvening" while str1 and str2 still maintain their original string value of "Good" and "Evening"
