用C语言函数设计求圆的面积矩形的面积-搜答案-搜搜考试网

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

#includedoublecalRectArea(doubledWidth,doubledHeigh){returndWidth*dHeigh;}voidmain(){doublea,b,mul;s

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

函数max()里max=x后面少了个分号#include "stdio.h"int max(int x,int y,int z){

#include<stdio.h>double zc(double x, double y){ ret

for(i=0;i

VC6通过#include#includefloatarea(floata,floatb,floatc){floatp=(a+b+c)/2;floatarea=0;area=sqrt(p*(p-a)*

#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

#include "stdio.h"double mianji(double x,double y){ r

#includeintgetArea(intlen){\x09returnlen*len;}intmain(){\x09intn;\x09intarea;\x09\x09printf("请输入边长:\

#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"stdio.h"//面积doublearea(doublelen,doublewid){returnlen*wid;}//周长doublecircle(doublelen,doubl

1:#include"stdio.h"\*此处可以不写,但是写上是好习惯,有些编译环境需要.*\int*fun(int*a,int*b,int*c)\*定义函数fun,其返回值为整型的指针*\{int

假设知道三角形的三边长为a,b,c.程序如下：#include#includedoublearea(doublea,doubleb,doublec){doublearea=0,s=0;s=(a+b+c

#include<stdio.h>#define Pi 3.14159double Square(double r){ &nb

三角形：inta,b,c;//三角形三边ints,d;d=(a+b+c)/2;s=(a-d)(b-d)(c-d);printf("areais%d",s);return0;

scanf("%d%d%d",&year,&month,&day); //这里不好区分
