项目一、数组分离

#include<iostream>
using namespace std;  
int main()  
{  
	const int N=5;
    double score[N],max,min,aver,i;
	cout<<"输入小组成绩：";
	for(i=0;i<N;i++) 	
	{
		cin>>score[i];
	}
		max=min=aver=score[0];
		for( i=1;i<N;i++)
		{
		aver+=score[i];
		if(score[i]>max) max=score[i];
		else if(score[i]<min) min=score[i];
		}
	aver=aver/10.0;
	cout<<max<<" "<<min<<" "<<aver;
	
	return 0;
}

项目3：成绩

<pre name="code" class="cpp">#include<iostream>
using namespace std;  
int main()  
{  
	const int N=10;
    int score[N],a[N],b[N],max,min,i,m=0,n=0,j=1,k=1;
	double aver;
	cout<<"输入小组成绩(0到100)：";
	for(i=0;i<N;i++) 	
	{
		cin>>score[i];
	}
	    max=min=aver=score[0];
	    for( i=1;i<N;i++)
		{
			aver+=score[i];
	    	if(score[i]>max) max=score[i];
	    	else if(score[i]<min) min=score[i];
		}
    	aver=aver/10.0;
    	cout<<"max="<<max<<endl;
		cout<<"min="<<min<<endl;
		cout<<"aver="<<aver<<endl;
		for( i=0;i<=N;i++)
		{
			if(score[i]==max) {m++;
			cout<<i+1<<" ";}
		}cout<<"号同学成绩最高"<<endl;
		for( i=0;i<=N;i++)
		{
			if(score[i]==min) {n++;
			cout<<i+1<<" ";}
		}cout<<"号同学成绩最低"<<endl;
		cout<<endl;
		cout<<"考得最高成绩的人数为："<<m<<"人"<<endl;
		cout<<"考的最低成绩的人数为："<<n<<"人"<<endl;
		return 0;
}

项目4：字符串

<pre name="code" class="cpp">#include<iostream>
using namespace std;  
int main()  
{  
    char str[50];  
    int i=0,x=0,y=0,z=0;  
    cout<<"输入字符串:";  
    gets(str);  
    while(str[i]!='\0')  
    {    
        if(str[i]>='0'&&str[i]<='9') x++;  
		else if((str[i]>='a'&&str[i]<='z')||(str[i]>='A'&&str[i]<='Z')) y++;
		else {z++;}
		i++;
    }  
    cout<<"其中的数字个数是: "<<x<<"个"<<endl;  
	cout<<"其中字母的个数是："<<y<<"个"<<endl;
	cout<<"其他字符的个数是："<<z<<"个"<<endl;
    return 0;  
}
