C语言—数组中“a,b,c”和{‘a’,‘b’,‘c’}的区别

arr1=“abc”——arr1有'\0','\0'也算一个字节

arr2={'a','b','c'}——arr2没有'\0'

1. #define _CRT_SECURE_NO_WARNINGS 1
3. #include<stdio.h>
4. int main()
5. {
6. char arr1[]="abc";
7. char arr2[]={'a','b','c'};
8. printf("%d\n",sizeof(arr1));
9. printf("%d\n",sizeof(arr2));
10. return 0;
11. }
