你上机调试一下,我得到的值:153 370 371 407
intjc(intx){returnx==1?1:jc(x-1)*x;}再问:可以编一个完整的么?我直接运行试一下。。。新手,不好意思,,,,谢谢再答:intjc(intx){returnx==1?1
上面是对的,f1是求体积的,f2是求表面积的.
int function(double **p, int p_r,int p_c, double **q,int q_r
includeincludeddoublefun(inta,intb,intc){intp;p=(a+b+c)/2;returnsqrt(p*(p-a)*(p-b)*(p-c));}再问:ok再问:
#include <stdio.h>float area(float r){ return 3.14159 *&nb
#include<stdio.h>#define Pi 3.14159double Square(double r){ &nb
#includeintgetArea(intlen){\x09returnlen*len;}intmain(){\x09intn;\x09intarea;\x09\x09printf("请输入边长:\
#include//doubleellipse_area(doublea,doubleb);intmain(void){doublea,b;doubles;printf("请输入椭圆的半长轴a,半短轴
#includeintstrl(char*s)//你需要的函数.{inti,k=0;for(i=0;s[i];i++)k++;returnk;}voidmain()//主函数,目的是测试下前面的函数.
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
main(){inta,b,c;//a是输入测试值,b是分段值,c是条件标志printf("inputthevalueandpercentils:\n");scanf("%d%d",&a,&b);//
平面是怎么个表达法图像么是以二维矩阵存储么再问:这个不知道啊你就看着题目办吧再答:那两个点有x,y坐标吧,point1,point2分别为点1和点2传入4个坐标值返回距离注意要有#includedou
