结构字符串warning提问

img

#include 
struct point{
    char name[20];
    int weigh;
    int height;
    
};
int main()

{
    struct point stu1,stu2;
    scanf("%s %d %d",stu1.name,stu1.weigh,stu1.height);
    printf("%s %d %d\n",stu1.name,stu1.weigh,stu1.height);
    stu2.name[20]="whs";
    stu2.weigh=135;
    stu2.height=180;
    printf("%s %d %d\n",stu2.name,stu2.weigh,stu2.height);
    return 0;
}

请问这个Warning表示我哪里输入错误了？
我输入完scanf后没有输出任何东西

scanf("%s %d %d",stu1.name,&stu1.weigh,&stu1.height); 缺&
stu2.name[20]="whs"; 字符串不能直接=复制，用strcpy
