运行通过，但是编译时出现了警告，原因不解，求教！
程序代码：#include<stdio.h>
int main()
{
int x,y;
printf("请输入x：\n");
scanf("%d",&x);
if(x<0) y=-1;
else if(x==0) y=0;
else y=1;
printf("x=%d,y=%d",x,y);
return 0;
}
警告 1 warning C4996: 'scanf': This function or variable may be unsafe. Consider using scanf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
