Question 6
Back to Exercise
What is the output of the following C program?
#include <stdio.h>
#include <string.h>
int main(void) {
char line[] = "a,,b,c";
int n = 0;
for (char *t = strtok(line, ","); t != NULL; t = strtok(NULL, ","))
n++;
printf("%d %s\n", n, line);
return 0;
}- A 4 a,,b,c
- B 3 a Correct
- C 3 a,,b,c
- D 4 a
Correct Answer: Option B
strtok() treats consecutive commas as one separator, so the tokens are a, b and c: 3. It also wrote '\0' after "a", so printing line now shows only "a".
