return 0;

}

题目二

#include 
#define pi 3.14
double calculateArea (int radius);
int main()
{
    int cRadius = 0;
    double area = 0.0;
    printf("输入圆的半径：\n");
    scanf("%d",&cRadius);
    area = calculateArea(cRadius);
    printf("圆面积是：%f \n",area);
    return 0;
 } 
 double calculateArea (int radius)
 {
    double result = pi* radius*radius;
    return result;
 }
