我想问一下这是哪里错了呀！

#include<stdio.h>
int main(void)
{
int height,length,volume,weight;
printf("Enter height of box:");
scanf("%d",&height);
printf("Enter length of box:");
scanf("%d",&length);
printf("Enter width of box:");
scanf("%d",`width);
volume = heightlengthwidth;
weight = (volume+165)/166;
printf("volume(cubic inches):%d",volume);
printf("Dimensional weight(pounds):%d\n",volume);
return 0;
}

对比下：看看

#include<stdio.h>
int main(void)
{
int height,length,volume,weight;
printf("Enter height of box:");
scanf("%d",&height);
printf("Enter length of box:");
scanf("%d",&length);
printf("Enter width of box:");
scanf("%d",&width);
volume = height * length * width;
weight = (volume + 165) / 166;
printf("volume(cubic inches):%d",volume);
printf("Dimensional weight(pounds):%d\n",volume);
return 0;
}

#include<stdio.h>
int main(void)
{
    int height, length, volume, weight, width;    //修改点1
    printf("Enter height of box:");
    scanf("%d", &height);
    printf("Enter length of box:");
    scanf("%d", &length);
    printf("Enter width of box:");
    scanf("%d", &width);                        //修改点2
    volume = height*length*width;                //修改点3
    weight = (volume + 165) / 166;
    printf("volume(cubic inches):%d", volume);
    printf("Dimensional weight(pounds):%d\n", volume);
    return 0;
}
