一奇偶阶乘

#include<iostream>using namespace std;int odd(int a[],int x);int  fact(int a[],int x);int main(){    int a[10]={1,2,3,4,5,6,7,8,9,10};    int i,j;    int s1=0,s2=0;    for(i=0;i<10;i++)    {        if(odd(a,i))        {            s1+=fact(a,i);        }        else s2+=fact(a,i);    }    cout<<s1<<" "<<s2<<endl;    return 0;}int odd(int a[],int x){    int p=0;//ÆæÊý    if(a[x]%2==0)    {        p=1;//Å¼Êý    }    return p;}int  fact(int a[],int x){    int i,s;    s=1;    for(i=1;i<=a[x];i++)    {        s*=i;    }    return s;}

二杨辉三角

#include<iostream>using namespace std;int odd(int a[],int x);int  fact(int a[],int x);int main(){    int a[10]={1,2,3,4,5,6,7,8,9,10};    int i,j;    int s1=0,s2=0;    for(i=0;i<10;i++)    {        if(odd(a,i))        {            s1+=fact(a,i);        }        else s2+=fact(a,i);    }    cout<<s1<<" "<<s2<<endl;    return 0;}int odd(int a[],int x){    int p=0;//ÆæÊý    if(a[x]%2==0)    {        p=1;//Å¼Êý    }    return p;}int  fact(int a[],int x){    int i,s;    s=1;    for(i=1;i<=a[x];i++)    {        s*=i;    }    return s;}

三统计数

#include<iostream>using namespace std;double aver(int x[],int p,double &m,double &n);int count(int x[],int n,double score,double sc);int main(){    int  x[10]={4,6,8,16,19,14,5,10,1,21},i,num;    double max,min;    double averscore;    averscore=aver(x,10,max,min);    cout<<"最大数为："<<max<<",最小数为："<<min<<",平均数为:"<<averscore;    num=count(x,10,i,averscore);    cout<<"大于平均数个数："<<num<<endl;    return 0;}double aver(int x[],int p,double &m,double &n){    m=n=x[0];    double s=0;    double ave;    int i;    for(i=1;i<p;i++)    {        if(x[i]>m)            m=x[i];        if(x[i]<x[0])            n=x[i];    }    for(i=0;i<p;i++)    {        s+=x[i];    }    ave=s/p;    return ave;}int count(int x[],int n,double score,double sc){    int i;    score=0;    for(i=0;i<n;i++)    {        if(x[i]>sc)            score++;    }    return score;}
