Question 4
Back to Exercise
The user types Asha Rao and presses Enter. What does the program print, and why?
#include <stdio.h>
int main(void) {
char name[32];
if (scanf("%31s", name) != 1)
return 1;
printf("Hello, %s!\n", name);
return 0;
}- A Hello, Asha Rao!
- B Hello, Asha! – %s stops reading at the first whitespace Correct
- C Hello, ! – %s skips letters
- D It overflows name
Correct Answer: Option B
%s reads a single word: it skips leading whitespace and stops at the next space. The 31 width is good practice (it prevents overflow). To read a full line, use fgets().
