C6054警告:可能没有为字符串添加字符串零终止符

当用一个字符数组作为字符串的缓冲区时,在定义数组时一定要初始化为0.

否则会提示C6054警告.

 1 #include <stdio.h>
 2 #include <string.h>
 3 #define MAX_LENGTH 10
 4 
 5 int main(void)
 6 {
 7     char str[MAX_LENGTH] = { 0 };
 8     scanf_s("%s", str, MAX_LENGTH);
 9     size_t len = strlen(str);
10     printf("str = [%s]\n", str);
11     printf("len = %u\n", len);
12     return 0;
13 }
