Answer

Correct Answer: India

Explanation

Introduction / Context:Here we test printf behavior when the format string has no conversion specifiers and an extra argument is passed. Understanding varargs and format processing helps prevent misuse and vulnerabilities.

Given Data / Assumptions:

  • The call is printf("India", "CURIOUSTAB").
  • "India" is a literal with no % placeholders.
  • printf prints exactly the format string, interpreting % directives if any.
  • Extra arguments with no matching conversion are ignored by the runtime formatting logic.

Concept / Approach:printf processes its first argument as a format string. If there are no conversion specifiers, it simply writes the format text. Although supplying extra arguments is undefined by strict standards discussions, practical implementations will not consume them because no % directives appear.

Step-by-Step Solution:Format string is "India".No % specifiers are present to consume subsequent arguments.printf therefore writes "India" to stdout.

Verification / Alternative check:Compile and run; you see "India" (without a newline). Adding "%s" to the format, as in printf("%s", "CURIOUSTAB"), would print the passed string.

Why Other Options Are Wrong:"India CURIOUSTAB" / "CURIOUSTAB": would require format placeholders.Error / No output: the code compiles and prints the literal.

Common Pitfalls:Thinking printf automatically prints all subsequent arguments; forgetting to include a newline or appropriate format specifiers.
