C语言：求下列图片上的题目，咋写？

Answer 1

代码文本：

#include "stdio.h"

#include "math.h"

int main(int argc,char *argv[]){

double x,y,e=2.718281828459;

printf("Enter x(R:)...\n");

scanf("%lf",&x);

if(x<-2.0)

y=sin(x+x)-5;

else if(x>=-2 && x<5.0)

y=sqrt(x+5);

else if(x>=5.0 && x<10.0)

y=pow(e,x+x)/(x+2.0);

else

y=-x*x+4.0;

printf("y(%.2f)≈%.2f\n",x,y);

return 0;

}
