C (Turbo C under DOS) — determine the program's output when executed with command-line arguments. Command used: cmd> sample Good Morning /* sample.c */ #include<stdio.h> int main(int argc, char *argv[]) { printf("%d %s", argc, argv[1]); return 0; } What will be printed to the screen?

Introduction / Context:This question checks understanding of how C command-line arguments are passed to main on DOS-based compilers such as Turbo C, and how argc (argument count) and argv (argument vector) influence the printed output.

Given Data / Assumptions:

• The program is invoked as: sample Good Morning.
• main signature is int main(int argc, char *argv[]).
• The program prints using printf("%d %s", argc, argv[1]).

Concept / Approach:In C, argv[0] holds the program name ("sample" here). Subsequent elements hold each argument token split on spaces: argv[1] = "Good", argv[2] = "Morning". argc is the count of tokens including the program name, so argc = 3 for this invocation.

Step-by-Step Solution:

Verification / Alternative check:Running with an extra token, e.g., sample A B C, makes argc = 4 and argv[1] = "A", confirming the pattern.

Why Other Options Are Wrong:

• 2 Good: Would imply argv[0] not counted, which is incorrect.
• Good Morning: The format prints an integer and a single string, not two strings.
• 3 Morning: argv[1] is "Good", not "Morning".

Common Pitfalls:Confusing argv[0] with the first user-supplied argument and assuming spaces remain as a single string without quoting.

Final Answer:3 Good
