我的这个C语言程序为什么错了啊

三点：1.double对应的是%lf，float对应的是%f；2.else if(t>=25&&t>27)应该是else if (t >= 25 && t =27); 此处的t>=27是多余的，更不应该有分号。

最后一个else后面不用跟(t>=27); 直接就是else printf("your weight is too heigh");

double要用%lf#includevoid main(){ double h,w,t; printf("please input your height\n"); printf("h="); scanf("%lf",&h); printf("please input your weight\n"); printf("w="); scanf("%lf",&w); printf("t="); t=(w/(h*h)); printf("%8.4lf\n",t); if(t=18&&t=25&&t<27) printf("You are over weight"); else printf("Your weight is too high");}
