编写C ,计算并显示半径为6.5的圆的面积和周长

#includeintmain(){floatr,s,l;scanf("%f",&r);s=3.14*r*r;l=2*3.14*r;printf("s=%f,l=%f\n",s,l);return0;

#include"stdio.h"intisprime(inta){intj;for(j=2;j

#includeintmain(){inta,sum=0;scanf("%d",&a);while(a){sum+=a%10;a/=10;}printf("sum=%d\n",sum);return0

main(){doubuti,j,v;intput(doubuti,doubutj);couti>>j;v=put(i,j);cout

#include"stdio.h"main(){inti,sum=0;for(i=126;i再问：能不能根据这个改下？？？？谢谢啦！！！#includeintmain(){inta;for(a=1

我刚刚编的,可以.不知道是不是你所要的.#includevoidmain(){intn;printf("欢迎来到计算整数的三次方的程序!\n");printf("请输入您要计算的数:");scanf(

#includevoidmain(){inta,i=0;scanf("%d",&a);while(a>10){i+=a%10;a/=10;}i+=a;printf("%d\n",i);}

先给个好评!再答：

main(){inta;intsum=0;foreach(a=1;a

你好.看代码#includevoidsort(int*a,int*b,int*c){intt;t=*a;*a=*a>*b?*a:*b;*b=*a>*b?*b:t;t=*a;*a=*a>*c?*a:*c

C编程求助编写一个基于对象的程序：输入半径,计算圆的周长和面积并输出实现#include

#includemain(){inta,b;floatm,n,sum;printf("请输入两个整数：\n");scanf("%d,%d",&a,&b);printf("请输入两个小数：\n");sc
