用C语言求圆的周长面积,圆球表面积体积,圆柱的体积

#include#definePI3.1415926doublearea(doubler){returnPI*r*r;}doubleperimeter(doubler){return2*PI*r;}i

#include#includeusingnamespacestd;intmain(){constfloatPI=3.1416f;floatr;cin>>r;floatc=2*PI*r;fl

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"stdio.h"#definePi3.1415926doublezhouchang(doubler){     doubles;&n

回楼主#include#definePI3.1415926intmain(){doubler,l,s;printf("请输入半径:");scanf("%lf",&r);if(

voidmain(){floatr,s,l;floatpi=3.1415;printf("输入一个圆的半径:\n");scanf("%f",&r);if(

圆柱的圆周长2πR圆面积πR2圆球表面积4πR2圆球体积4/3πR3圆柱体积πR2*H

#includeintmain(){intr;printf("请输入r：");scanf("%d",&r);printf("面积是：%f\n",2*3.1415*r*r);return0;}再问：没有

1.#includeintmain(){floatr,s,l,v;printf("请输入半径\n");scanf("%f",&r);s=3.14*r*r;l=2*3.14*r;v=4.0/3.0*3.

代码大致思路没有错.不过,采用浮点型数据的时候,输入输出的格式不是用%d（整数）,而是用%f所以,把你的代码里,%ld改成%lf,%d改成%f,%.6ld改成%.6lf就可以了.另外,面积公司改成ar

#include#includepublicvoidmain(){doublea,b,c;scanf("%lf%lf%lf",&a,&b,&c);doublearea,preimeter;preime

#includeintmain(){intr=0;floata=0,l=0;scanf("%d",&r);a=r*r*3.14;l=r*2*3.14;printf("面积:%f,周长:%f",a,l)

#include#definepi3.14159main(){doubleL,S,V,A,B;/*L是圆周长,S是圆面积,V是圆球体积,A是圆球表面积,B是圆柱面积*/floatr,h;printf(

#include#definePremeter(a,b)2*(a+b)#defineArea(a,b)a*bintmain(){doublea,b;printf("请输入矩形的长和宽:\n");sca

#include#includemain(){doublearea,length;doubler=pi=3.1215926area=pi*r*r；length=2*pi*r；}
