c写一个计算输血量,男性体重大于120kg,应输入200mm,小于120kg, 为180mm,女性

体重大于100kg，应输入200mm，小于100kg，应输入150mm。下面是示例代码：

#include <stdio.h>

int main() {
char gender;
float weight, height;

printf("请输入性别(m/f)和体重(kg): \n");
scanf("%c %f", &gender, &weight);

if (gender == 'm') {
if (weight > 120) {
height = 200;
} else {
height = 180;
}
} else if (gender == 'f') {
if (weight > 100) {
height = 200;
} else {
height = 150;
}
} else {
printf("非法的性别输入\n");
return -1;
}

printf("输血量为: %.1fmm\n", height);

return 0;
}
