c++ - I get 4 when I use scanf_s but 1 when I use fgets()? -

#include "stdafx.h" #include <stdio.h> #include <string.h>  void main() {     char s[200];     int count = 0, i;      printf("enter string\n");     //scanf_s("%[^\n]s", s, sizeof(s));     fgets(s, sizeof*(s), stdin);     (i = 0;s[i] != '\0';i++)     {         if (s[i] == ' ')         count++;     }     printf("number of words in given string are: %d\n", count + 1);     getchar(); } 

fgets(s, sizeof*(s), stdin); -- wrong. should sizeof(s)

the *(s) character (first element of array), while s array. because single character of size 1, got 1.
