Question

c语言的问题，麻烦大神解决一下，谢谢

#include <stdio.h>
int main()
{
char sex, F,M,Y,N,sports, diet;
double faHeight, moHeight, h,h1=0,h2=0;
printf("请输入父亲身高（cm）");
scanf("%lf",&faHeight);
printf("请输入母亲身高（cm）");
scanf("%lf", &moHeight);
h1=faHeight,h2=moHeight;
printf("请输入孩子性别（F:女性，M:男性）");
scanf("%*c%*C",&sex);
printf("是否喜爱体育锻炼(Y/N)?");
scanf("%*c%*C",&sports);
printf("是否有良好饮食习惯(Y/N)?");
scanf("%*c%*C",&diet);
if (sex == 'F')
{ if(sports==Y)
{if(diet==Y)
{h=(0.923*h1+h2)/2*1.035;
}
else
{h= (0.923*h1+h2)/2*1.02;
printf("我的身高:%lf",h);
}
}

首先 你写的是主函数 主函数没有返回值 所以用void main就行
然后 if里面的字符要加‘’单引号，如果是字符串的话 要加双引号
还有 如果是出现了error C2018: unknown character '0xa1'这样的错误提示，表示错误行输入了全角空格 vc++不识别 所以只要把空格删掉就好了

满意了就给分吧
