Question

C语言编程问题，初学者，麻烦简单些，谢谢(*°∀°)=3？

输入性别（0代表男性，1代表女性）、身高和体重，输出“正常体重”“体重过重”“体重过轻”“肥胖”“体重不足”。
世卫计算方法：
男性：(身高cm－80)×70﹪=标准体重 女性：(身高cm－70)×60﹪=标准体重
标准体重正负10﹪为正常体重
标准体重正负10﹪~ 20﹪为体重过重或过轻
标准体重正负20﹪以上为肥胖或体重不足

Answer 1

#include "stdio.h"

int main()

{

int sex,height;

float weight,bzweight;//输入体重和标准体重

printf("输入性别（0-男性,1-女性）:");

scanf("%d",&sex);

printf("输入身高（cm）:");

scanf("%d",&height);

printf("输入体重（kg）:");

scanf("%f",&weight);

if(sex==0)

bzweight=(height-80)*0.7;

else

bzweight=(height-70)*0.6;

if(((weight-bzweight)/weight>=-0.1)&&((weight-bzweight)/weight<=0.1))

printf("正常体重\n");

else if(((weight-bzweight)/weight>0.1)&&((weight-bzweight)/weight<=0.2))

printf("体重过重\n");

else if(((weight-bzweight)/weight>-0.2)&&((weight-bzweight)/weight<-0.1))

printf("体重过轻\n");

else if((weight-bzweight)/weight>0.2)

printf("肥胖\n");

else if((weight-bzweight)/weight<=-0.2)

printf("体重不足\n");

printf("%.2f\n",(weight-bzweight)/weight);

return 0;
