float BMI(float height, float weight);
float BMI;
这两句同“名”
BMI=(height,weight); 这句想做什么？

#include<stdio.h>
float BMI(float height, float weight);

int main()
{
    float height;
    float weight;
    printf("请输入您的身高： \n");
    scanf("%f",&height);
    printf("请输入您的体重： ");
    scanf("%f",&weight);
    printf("您的BMI为：");
    printf("%f\n",BMI(height,weight));
    return 0;
}

float BMI(float height, float weight)
{
    float BMI =(weight*height);
    return BMI;
}
