谁帮我改下代码。。。。。

#include<stdio.h>
int main(void)
{
char sex,sport,diet;

double faHeight,moHeight,kidHeight;

printf("faHeight and moHeight=%lf%lf",faHeight,moHeight);

scanf("%lf%lf",faHeight,moHeight);

printf("sex=%c",sex);

sex=getchar();

printf("sport=%c",sport);

sport=getchar();

printf("diet=%c",diet);

diet=getchar();
kidHeight=0;

switch(sex){
case'M':
if((sport=='Y')&&(diet=='N')){
kidHeight=(faHeight+moHeight)*0.54*1.02;
printf("kidHeight=%lf\n",kidHeihgt);
}
else if((sport=='N')&&(diet=='Y')){
kidHeight=(faHeight+moHeight)*0.54*1.015;
printf("kidHeight=%lf\n",kidHeight);
}
else if((sport=='Y')&&(diet=='Y')){
kidHeight=(faHeight+moHeight)*0.54*1.02*1.015;
printf("kidHeight=%lf\n",kidHeight);
}
else if((sport=='N')&&(diet=='N')){
kidHeight=(faHeight+moHeight)*0.54;
printf("kidHeight=%lf\n",kidHeight);
}
else{
printf("some of errors!\n");
}
break;
case'F':
if((sport=='Y')&&(diet=='N')){
kidHeight=(faHeight*0.923+moHeight)/2*1.02;
printf("kidHeight=%lf",kidHeight);
}
else if((sport=='N')&&(diet=='Y')){
kidHeight=(faHeight*0.923+moHeight)/2*1.015;
printf("kidHeight=%lf",kidHeight);
}
else if((sport=='Y')&&(diet=='Y')){
kidHeight=(faHeight*0.923+moHeight)/2*1.02*1.015;
printf("kidHeight=%lf",kidHeight);
}
else if((sport=='N')&&(diet=='N')){
kidHeight=(faHeight*0.923+moHeight)/2;
printf("kidHeight=%lf",kidHeight);
}
else{
printf("some of errors!\n");
}
break;
default:
printf("some of errors!\n");
break;
}
return 0;
}

为什么编译出错了。。。

有几处小错误，用你改动下，由于只是要帮你改错，故没做程序结构调整

#include<stdio.h>
int main(void)
{
char sex,sport,diet;

double faHeight,moHeight,kidHeight;

printf("请输入faHeight和moHeight,两值之间用空格区分开\n");

scanf("%lf %lf",&faHeight,&moHeight);
getchar();//用于接收缓冲区的回车符，下面的getchar用途一样

printf("请输入sex，值为M或F\n");

sex=getchar();
getchar();

printf("请输入sport，值为N或Y\n");

sport=getchar();
getchar();

printf("请输入diet，值为N或Y\n");

diet=getchar();
getchar();
kidHeight=0;

switch(sex){
case'M':
if((sport=='Y')&&(diet=='N')){
kidHeight=(faHeight+moHeight)*0.54*1.02;
printf("kidHeight=%lf\n",kidHeight);
}
else if((sport=='N')&&(diet=='Y')){
kidHeight=(faHeight+moHeight)*0.54*1.015;
printf("kidHeight=%lf\n",kidHeight);
}
else if((sport=='Y')&&(diet=='Y')){
kidHeight=(faHeight+moHeight)*0.54*1.02*1.015;
printf("kidHeight=%lf\n",kidHeight);
}
else if((sport=='N')&&(diet=='N')){
kidHeight=(faHeight+moHeight)*0.54;
