How do you read scanf until EOF in C?

Question

I have this but once it reaches the supposed EOF it just repeats the loop and scanf again.

int main(void) {         char words[16];          while(scanf("%15s", words) == 1)            printf("%s\n", words);          return 0; } 

Answer 1

Try:

while(scanf("%15s", words) != EOF) 

You need to compare scanf output with EOF

Since you are specifying a width of 15 in the format string, you'll read at most 15 char. So the words char array should be of size 16 ( 15 +1 for null char). So declare it as:

char words[16];
