写一段计算热膨胀系数的C语言代码

#include <stdio.h>

int main() { float length1, length2, delta_l, temperature, alpha;

printf("请输入原始长度：");
scanf("%f", &length1);

printf("请输入变化后长度：");
scanf("%f", &length2);

delta_l = length2 - length1;

printf("请输入温度变化量：");
scanf("%f", &temperature);

alpha = delta_l / (length1 * temperature);

printf("热膨胀系数为：%f\n", alpha);

return 0;

}
