Concatenation operator
#NAME?
Concat function
Cat function
Answer is Right!
Answer is Wrong!
The correct answer is: A. Concatenation operator.
The concatenation operator is used to concatenate two or more strings. It is a plus sign (+). For example, the following code will concatenate the strings “Hello” and “World”:
String str1 = "Hello";
String str2 = "World";
String str3 = str1 + str2;
The result of the code will be the string “HelloWorld”.
The other options are incorrect. Option B, the + symbol, is the concatenation operator. Option C, the Concat function, is not a valid function in most programming languages. Option D, the Cat function, is a valid function in some programming languages, but it is not as common as the concatenation operator.
