有以下程序
#include＜stdio.h＞
main()
int x:
scanf("%d",＆x);
if(x＜=3);else
if(x!=10)printf("%d\n",x);

程序运行时，输入的值在哪个范围才会有输出结果______。

A．y=sqrt(x);
if(x＜0)y=sqrt(-x);
B．if(x＞0)y=sqrt(x);
else y=sqrt(-x);
C．if(x＞=0)y=sqrt(x);
if(x＜0)y=sqrt(-x);
D．y=sqrt(x＞=0x:-x);

A．k=(a＜b)((a＜c)a:c):((b＜c)h:c);
B．k=(a＜b)((b＜c)a:b):((h＞c)b:c);
C．k=(a＜b)a:b;k=(b＜c)b:c;
D．k=(a＜b)a:h:k=(a＜c)a:c;
