#definePI3.1416//后面不需要;#include"stdio.h"//注意关键字之间要有空格intmain(){floatr,s,c;scanf("%f",&r);c=2*PI*
在输入半径的时候,语句改成scanf("%d",&r);不过你最好将半径定义成float型变量,格式的问题

楼上的方法应该没错,可感觉对于表现java面向对象的特性没有表现出来,下面是我写的,应该非常清楚明了了importjava.io.BufferedReader;importjava.io.InputS

、s和l变量建议定义成float或double类型,另外出于养成良好的习惯,最好是将π定义成常量const输入建议scanf("%f\n",&r);输出建议使用printf(%f\n%f\n",l,s
