1，编程题目解答

#include<iostream>using namespace std;void main()int i=0;for(;i!=13;++i)cout<<a[i]<<" ";getchar();}
定义一个数组然后输入上述数据，再输出即可

2，计算机编程题目

#include"iostream.h"double fac(int n) if(n<2) return 1; }else return n*fac(n-1); }}double sum(int n) if(n<1) return 0; }else return sum(n-1)+1/fac(n); }}void main(void) cout<<"1+1/2!+1/3!+1/4!+1/5!="<<sum(2)<<endl;}
额，c++还没学，c可以。。。

#include#include #include #include #include class Shape {protected: int x1;int y1; public:Shape(int x,int y) {x1=x;y1=y;} }; class Rectangle: public Shape {protected: int x2;int y2; public:Rectangle(int x,int y,int a,int b):Shape(x,y,a,b),x2(a),y2(b) {} int area(){return (|x1-x2|*|y1-y2|);} } int main() { ifstream in("shape.txt"); for(string s;getline(in, s);) {int x1,x2,y1,y2; for(istringstream sin(s);sin>>x1>>x2>>y1>>y2;); } Rectangle R(x1,x2,y1,y2); cout<<"长方体的面积:"<<

5，编程题简单的

double fun(int n) int i; double sum=0; for(i=1;i<=2n+1;i+=4) sum+=double(1/i); for(i=3;i<=2n+1;i+=4) sum-=double(1/i); return sum; }
用JAVA语言做的，代码如下： import java.util.Scanner; public class test public static void main(String[] args) // TODO Auto-generated method stub String s="s=1"; Scanner input=new Scanner(System.in); System.out.println("请输入n的值："); int n=input.nextInt(); for(int i=1;i<n+1;i++) if(i%2==0) s+="+1/"+(2*i+1); }else s+="-1/"+(2*i+1); } } System.out.print(s); }}
