我调试的时候输出的第三行和第四行是在一起的 而且总是在那里运行出错

#include <stdio.h>

int main()
{
    double faHeight, moHeight, Height;
    char sex, sports, diet;
    printf("请输入你父亲的身高:");
    scanf("%lf", &faHeight);
    printf("请输入你母亲的身高:");
    scanf("%lf", &moHeight);
    printf("请确定你的性别(m为男，f为女):");
    scanf("%s", &sex);
    printf("请问你是否喜欢体育锻炼(Y为喜欢，N为不喜欢):");
    scanf("%s", &sports);
    printf("请问你是否有良好的饮食习惯(Y为喜欢，N为不喜欢):");
    scanf("%s", &diet);
    if (sex == 'm' || sex == 'M')
        Height = (faHeight + moHeight)*0.54;
    if (sex == 'f' || sex == 'F')
        Height = (faHeight*0.923 + moHeight) / 2;
    if (sports == 'Y') {
        if (diet == 'Y')
            Height = Height*1.035;
        if (diet == 'N')
            Height = Height*1.02;
    }
    if (sports == 'N') {
        if (diet == 'Y')
            Height = Height*1.015;
        if (diet == 'N')
            Height = Height*1.00;
    }
    printf("你的身高可能为:%lf cm\n", Height);
    return 0;
}


回车符被scanf吸收了。这样s和c不匹配，却能运行。
