运行程序出现了一个id.exe的文件
#include<stdio.h>#include<math.h>
main()
{
int a=12;
int b=18;
int e=31;
int d=4;
int c=100;
int x=23;
printf("%d\n",(sin(x)*sin(x))*(a+b)/(a-b));
printf("%d\n",20<x<30||x<-100);
printf("%f\n",(1/2)*((a*x)+((a+x)/(4*a))));
printf("%f\n",sqrt(sqrt(sin(x)*sin(x)*sin(x)*sin(x)*sin(x))));
printf("%f\n",3*a*e/(c*d));
printf("%d\n",'a'>>4);
}
运行,然后就出现了好多十六进制的文件
