Verbatim and raw string literals in C Sharp (C#) - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

intermediate

Output of verbatim string with escape sequences

What is the output of this C# code snippet?

C Sharp (C#)

string path = @"C:\Users\Admin\Documents";
Console.WriteLine(path);

A C:/Users/Admin/Documents

B C:\\Users\\Admin\\Documents

C C:\Users\Admin\Documents

D C:UsersAdminDocuments

💡 Hint

Remember that verbatim strings treat backslashes as normal characters.

The @ symbol before the string makes it verbatim, so backslashes are not escape characters but literal backslashes.

Output of raw string literal with multiple lines

What will this C# code print?

C Sharp (C#)

string json = """
{
  "name": "Alice",
  "age": 30
}
""";
Console.WriteLine(json);

A

{
  "name": "Alice",
  "age": 30
}

B { "name": "Alice", "age": 30 }

C {\n \"name\": \"Alice\",\n \"age\": 30\n}

D

{
  name: Alice,
  age: 30
}

💡 Hint

Raw string literals preserve all whitespace and line breaks exactly.

Raw string literals keep the text exactly as typed, including new lines and quotes without needing escapes.

Identify the error in verbatim string usage

What error will this code produce?

C Sharp (C#)

string text = @"This is a "quoted" word.";

A SyntaxError: Invalid string literal due to unescaped quotes inside verbatim string

B No error, prints: This is a "quoted" word.

C Compilation warning: Use double quotes to escape inside verbatim string

D RuntimeException: Unterminated string literal

💡 Hint

How do you include double quotes inside a verbatim string?

Inside verbatim strings, double quotes must be doubled to be included literally.

Output of raw string literal with embedded quotes

What is the output of this C# code?

C Sharp (C#)

string poem = """""Roses are red,
"Violets" are blue.
""""";
Console.WriteLine(poem);

A

"""Roses are red,
"Violets" are blue.
"""

B

"Roses are red,
"Violets" are blue.
"

C

Roses are red,
Violets are blue.

D

Roses are red,
"Violets" are blue.

💡 Hint

Raw string literals can contain quotes without escaping if the delimiter count is sufficient.

The raw string literal uses 5 quotes as delimiter, so inner quotes are preserved as is without escapes or delimiters.

Difference between verbatim and raw string literals

Which statement correctly describes the difference between verbatim (@) and raw (""""" or more quotes) string literals in C#?

A Raw strings require doubling backslashes, verbatim strings do not allow new lines inside.

B Verbatim strings allow escape sequences like \n, raw strings preserve all characters including new lines and quotes without escapes.

C Verbatim strings preserve new lines and quotes without escapes, raw strings require escaping quotes.

D Raw strings are only for single-line strings, verbatim strings are for multiline strings.

💡 Hint

Think about how each treats backslashes, new lines, and quotes.

Verbatim strings treat backslashes literally but still require doubling quotes. Raw strings preserve everything exactly, including new lines and quotes, without escapes.
