Answer 1

#include <stdio.h>

int main()
{
    char sex;
    double faHeight,moHeight,height;
    printf("请输入孩子性别(b or g)、父亲身高(cm)和母亲身高(cm)：");
    scanf("%c %lf %lf",&sex,&faHeight,&moHeight);//1、这里是&faHeight,&moHeight 2、double类型用%lf
    if (sex=='b') //这里是==，不是=
    {
        height = (faHeight + moHeight)*0.54;
    }
    else{
        height =  (faHeight*0.923 + moHeight)/2;
    }
    printf("小孩的身高为%6.2f(cm)",height);
    return 0;
}
