如下程序有什么错误，请高手指正

Question

#include <stdio.h>#include <string.h>void main(){int length;char answnum[10]={"123456"};length=strlen(answunm);printf("%d",length);}

Answer 1

char answnum[10] = {"123456"};
改为:
char answnum[10] = {'1','2','3','4','5','6'};

Answer 2

不能
strlen是字符串的函数

Answer 3

strlen(answunm)中的answunm写错了u和n的顺序错了
