C#输入圆的半径,输出圆的面积和周长

CLEARSETTALKOFFINPUT"请输入半径:"TORL=2*PI()*RS=PI()*R*R"半径为R的圆的周长为:",L"半径为R的圆的面积为:",SSETTALKON

编写一个程序,输入a,b,c三个值,按从小到大的顺序输出.C#staticvoidMain(string[]args){inta,b,c;Console.WriteLine("请输入三个数");a=i

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

#include#definePI3.1415926\x05\x05voidmain()\x05{\x05doubler,s;scanf("%f",&r);s=PI*r*r;\x05printf("A

function[SV]=sphere(R)%定义函数S=pi*R^2;%求圆的面积V=4/3*pi*R^3;%求求的体积调用方法[ab]=sphere(1)

要求用什么语言啊?求简单写个在matlab上跑的：r=input('r=?');D=2*pi*rS=pi*r*r再问：c语言呀哥哥再答：#include#includemain(){floatpi=3

#includevoidmain(){floatr,d,Cs;cout

亲,这个是源码using System;using System.Collections.Generic;using System.Linq;using Sys

他们的答案好像都没有输出结果.Dim r, s, c As IntegerPrivate Sub Command1_Click()

第一段程序：m=pie*r*r,这句逻辑上有问题,m为输入值,r未赋值,默认0,for(i=1;i
