蓝桥杯算法提高VIP-分数统计 （C++代码）

写的不好，见谅！

参考代码:

#include <iostream>
#include <algorithm>
using namespace std;
bool cmp(int a,int b)
{
    return a>b;
}
int main()
{
    int a=0,b=0,c=0,d=0,e=0,n,s[1005];
    cin>>n;
    for(int i=0;i<n;i++){
        cin>>s[i];
        if(90<=s[i]&&s[i]<=100)a++;
        else if(80<=s[i]&&s[i]<=89)b++;
        else if(70<=s[i]&&s[i]<=79)c++;
        else if(60<=s[i]&&s[i]<=69)d++;
        else e++;
    }
    sort(s,s+n,cmp);
    cout<<a<<" "<<b<<" "<<c<<" "<<d<<" "<<e<<endl;
    int max=a;
    if(max<b)max=b;
    if(max<c)max=c;
    if(max<d)max=d;
    if(max<e)max=e;
    cout<<max<<endl;
    if(max==a){
        for(int i=0;i<n;i++){
            if(90<=s[i]&&s[i]<=100)
                cout<<s[i]<<" ";
        }
        cout<<endl;
    }
    if(max==b){
        for(int i=0;i<n;i++){
            if(80<=s[i]&&s[i]<=89)
                cout<<s[i]<<" ";
        }
        cout<<endl;
    }
    if(max==c){
        for(int i=0;i<n;i++){
            if(70<=s[i]&&s[i]<=79)
                cout<<s[i]<<" ";
        }
        cout<<endl;
    }
    if(max==d){
        for(int i=0;i<n;i++){
            if(60<=s[i]&&s[i]<=69)
                cout<<s[i]<<" ";
        }
        cout<<endl;
    }
    if(max==e){
        for(int i=0;i<n;i++){
            if(0<=s[i]&&s[i]<=59)
                cout<<s[i]<<" ";
        }
        cout<<endl;
    }
    return 0;
}
