Question

c语言 分段函数 输入x的值，根据以下分段函数求出相应的y

Answer 1

#include<stdio.h>
#include<math.h>
int main()
{double x,y;
 scanf("%lf",&x);
 if(x<=-2&&x!=5)y=x*x+1/(x+5);
   else if(x>-2&&x<=0)y=sqrt(x+2)+x*x*x;
     else if(x>0&&x<=10)y=log(x+5)/log(10)+exp(x-1);
       else y=fabs(x-20);
 printf("%lf\n",y);
 return 0;
}
