#include<stdio.h>

int main()
{
int i;
float weight=65.0;
float height=1.72;
float wgt_ratio;
printf("\n\t体重\t身高\t体重指数\n");
weight=weight-5.0;
for(i=0;i<10;i++)
{
wgt_ratio=weight/(height*height);
printf("\t%.1f\t%.2f\t%.1f\n",weight,height,wgt_ratio);
weight=weight+1.0;
}
return 0;
}
此程序完全符合题目要求，你可以运行试一试。

Answer 3

# include <stdio.h>

int main()
{
	float bmi = 0.0,height;//定义变量“身高”，”体重指数“
    int weight;//”体重“

	//bmi = weight / (height * height);

	printf("请输入你的身高(米)：");
	scanf("%f",&height);

	printf("\t体重（千克）身高（米）\t体重指数\n");

	for (weight = 30 ; weight < 100 ; weight ++)//从10到50循环体重数
	{
	
		printf("\t%d\t%f\t%f",weight,height, weight / (height * height));//输出

		if (weight / (height * height) > 18 && weight / (height * height) < 25)//在正常体重范围内
		{
			printf("\t您的体重正常！\n");
		}
		else if (weight / (height * height) > 25 && weight / (height * height) < 30)
		{
			printf("\t您超重了！\n");
		}
		else if (weight / (height * height) > 30)
		{
			printf("\t您轻度肥胖\n");
		}
		else if (weight / (height * height) > 35)
		{
			printf("\t 您中度肥胖！\n");
		}
		else if (weight / (height * height) < 18)
		{
			printf("\t您过轻！\n");
		}
		else
		{
			printf("\t您重度肥胖！");
		}

	}

	return 0;
}
