#include<stdio.h>
int main()
{
    float h,w,x;
    printf("Enter your height and weight");
    scanf("%f %f",&h,&w);
    w/(h*h)==x;
    scanf("%f",&x);
    if(x<=18.5)
    {printf("You are UNDER WEIGHT");
    }
    else if("x==(18.5&&24.9)")
    {printf("You are AVERAGE");
    }
    else if("x>=(25&&29.9)")
    {printf("You are OVER WEIGHT");
    }
    else
    {printf("OBESITY!!!");
    }
    return 0;
}

我是编程的初学者。我想使用嵌套的if else语句来做一个复杂的程序。但是我不能执行上面的代码。你能帮助我吗 ? 对不起,我很笨。提前致谢 :)

最佳答案

更改

w/(h*h)==x;
scanf("%f",&x);


if(h) //if h is not zero
    x=w/(h*h); //calculate x

还有这些
else if("x==(18.5&&24.9)")
else if("x>=(25&&29.9)")


else if(x>18.5 && x<=24.9)
else if(x>=25 && x<=29.9)
