Which operator is used to concatenate two strings?Select one:a.+(Plus)b.*(Asteric)c..(Dot)d.All of the abov

Break Down the Problem

1. Identify the operators used in programming for string concatenation.
2. Analyze the options provided and determine which operator is correct.

Relevant Concepts

• In many programming languages, string concatenation is often performed using specific operators:
  • Plus (+): Commonly used in languages like Python and Java.
  • Dot (.): Used in languages like PHP and Perl.
  • Asterisk (*): Typically represents multiplication, not concatenation.

Analysis and Detail

1. The Plus (+) operator can concatenate strings in several programming languages (e.g., Java, JavaScript, Python).
2. The Dot (.) operator is specifically used for concatenation in languages like PHP.
3. The Asterisk (*) operator is not used for concatenation in any standard programming language; its primary function is for multiplication.
4. The option "All of the above" cannot be true, as not all listed operators perform string concatenation.

Verify and Summarize

• The options a (Plus) and c (Dot) are valid for string concatenation in certain programming languages, while the b (Asterisk) is not. Therefore, the correct choice would not include the asterisk.

Final Answer

The correct operators used for concatenating two strings are:

• a. + (Plus)
• c. . (Dot)

Thus, the answer is a + c. However, since only one option is typically acceptable, a. + (Plus) is the most universally recognized string concatenation operator.
