项目1：数组分离

#include <iostream>  
using namespace std;  
int main()  
{   
    int a[5],b[5],c[5],d=0,e=0,i,j;
	
	for(i=0;i<5;i++) 
		cin>>a[i];  
    for(j=0;j<5;j++)
	{
		if(a[j]%2==0) 
		{   b[d]=a[j];
		d++;
		}
		else
		{  c[e]=a[j];
		e++;}
	}
    for(i=0;i<d;i++)
        cout<<b[i]<<"   ";
	cout<<"\n";
	for(i=0;i<e;i++)
		cout<<c[i]<<"   ";
	cout<<"\n";
    cout<<endl;  
    return 0;  
}  

 项目3：成绩

#include<iostream>
using namespace std;  
int main()  
{   
    int i,a,score[20],b=0,c,d,x=0,y=0;
	int j[10],k[10];
	cout<<"请输入人数：";
	cin>>a;
	cout<<"请输入成绩："<<endl;
	for(i=1;i<=10;i++)
		cin>>score[i];
	c=d=score[1];
	for(i=1;i<=10;i++)
		if(score[i]>d)
			d=score[i];
		for(i=1;i<=10;i++)
		{
			if(score[i]<c)
				c=score[i];
		}
		for(i=1;i<=10;i++)
			b=b+score[i];
		for(i=1;i<=10;i++)
			if(score[i]==d)
			{
				j[x]=i;
				x++;
			}
			for(i=1;i<=10;i++)
				if(score[i]==c)
				{
					k[y]=i;
					y++;
				}
				cout<<"最高分为"<<d<<","<<"最低分为"<<c<<","<<"平均分为"<<b/10<<","<<endl;
				cout<<"考最高分的人数为"<<x<<","<<"考最低分的人数为"<<y;
				cout<<"\n";
				cout<<"考最高分的人的学号为";
				for(i=0;i<x;i++)
					cout<<j[i]<<",";
				cout<<"考最低分的人的学号为";
				for(i=0;i<y;i++)
					cout<<k[i]<<",";
				cout<<endl;
				return 0;  
}  

#include<cstdio>    
using namespace std;  
int main()  
{  
    char str[50];  
    int a=0,b=0,c=0,d=0,i=0;  
    cout<<"输入字符串:";  
    gets(str);  
    while(str[i]!='\0')  
    {    
        if(str[i]>='0'&&str[i]<='9')  
        a++;
		else if(str[i]>='a'&&str[i]<='z')
		b++;
		else if(str[i]>='A'&&str[i]<='Z')
		c++;
		else
		d++;
        i++;
    }  
    cout<<"其中的数字个数是: "<<a<<"个,"<<"小写字母有"<<b<<"个,"<<"大写字母有"<<c<<"个,"<<"其他字母有"<<d<<"个,"<<endl;  
    return 0;
}
