}
不知道为什么会跳出来这个！
#include <stdio.h>
#define PI (3.141592653)
int main()
{
int number2;
double C,A;
printf("Enter int:");
scanf("%d",&number2);
C = 2*PI*number2;
A = PI*number2*number2;
printf("A circle with radius %d has circumference of %.3f and an area of %.3f\n",number2,C,A);
scanf("%*c");
return 0;
}
#define PI (3.141592653)
int main()
{
int number2;
double C,A;
printf("Enter int:");
scanf("%d",&number2);
C = 2*PI*number2;
A = PI*number2*number2;
printf("A circle with radius %d has circumference of %.3f and an area of %.3f\n",number2,C,A);
scanf("%*c");
return 0;
}

奇怪最后那句干嘛的scanf("%*c");
