帮忙看一下错在什么地方？
#include <stdio.h>#include <string.h> //提供strlen()函数的原型
#define DENSITY 62.4 //人的密度（单位是：英镑/每立方英尺）
int main(void)
{
float weight;
float volume;
int size;
int letters;
char name; // name 有一个有40个字符的数组
printf("Hi! What's your first name?\n");
scanf_s("%s", name);
printf("%s, what's your weight in pounds?\n", name);
scanf_s("%f", &weight);
size = sizeof name;
letters = strlen(name);
volume = weight / DENSITY;
printf("Well, %s, your volume is %2.2f cubic feet.\n",
name, volume);
printf("Also, your first name has %d letters,\n",
letters);
printf("and we have %d bytes to store it in.\n", size);
return 0;
}

scanf_s() 在输入字符串时，必须有一个参数，用来指明用于保存字符串变量的字符容量。
为这一句添加蓝色字符部分试试看呢。
scanf_s("%s", name,40) ; 巴巴鲁 发表于 2020-10-18 12:03
