while((scanf("%lf%lf%lf",&a,&b,&c))==3)怎么理解?

while((scanf("%lf%lf%lf",&a,&b,&c))==3)怎么理解? while(scanf("%lf",&x)!=EOF) scanf("%lf",&a) 谁知道scanf("%c:%lf%*c",&c,&a); %.lf%%, scanf("%lf%lf%lf",&a,&b,&c)其中的l是什么意思 为什么我去掉L是编译成功 可1运行程序就退出来 #include main() { double a,b,c,d,e; scantf("lf%lf%lf%",a,b,c #includevoid main(){double p,w,a,d,f;scanf("%lf %lf %lf",&p, C语言 %lf 和 scanf("%s%lf%d",card[i].name,&card[i].value,&card[ printf("'e' raised to the power \of %lf (e ^ %lf) = %lf\n",x main() { double x,n,sum=0; scanf("%lf",&n); if (((int)n%2)!= 在scanf()函数的格式说明符中,长整型数的输入格式符是 A.%ld B.%lf　 C.%d D.%x
