题目描述

销售部新进了一台快速打印机,使用频率很高。为了能够对打印情况进行统计,规定每个人在打印后需要登记时间和用纸张数。

注:本题只需要提交修改和完善部分的代码,请按照C++方式提交。

#include <iostream>
using namespace std;
class FastPrinter
{
public:
    FastPrinter() {}
    FastPrinter(int year,int month,int day,int num);
    ~FastPrinter() {}
    void PrintJob() {}
    static unsigned int getcounts()
    {
        return counts;
    }
    static unsigned int gettotals()
    {
        return totals;
    }
private:
    static unsigned int counts;
    static unsigned int totals;
    int year,month,day;
};
/* 修改和完善该部分代码
unsigned int FastPrinter::counts = 0;
FastPrinter::FastPrinter(int year,int month,int day,int num):year(year),month(month),day(day)
{
    totals++;
}
*/
int main()
{
    FastPrinter *fp;
    int year,month,day,num;
    int n,m;
    cin>>n;
    while(n–)
    {
        cin>>m;
        while(m–)
        {
            cin>>year>>month>>day>>num;
            fp=new FastPrinter(year,month,day,num);
            fp->PrintJob();
            delete fp;
        }
    }
    cout<<"打印次数:"<<FastPrinter::getcounts()<<",张数:"<<FastPrinter::gettotals()<<endl;
    return 0;
}

输入

第一行n表示下面n个部门
第二行开始分别为每个部门的数据
对于每个部门,
    第一行m表示该部门打印的次数
    接来下m行给出打印的时间(年月日)和打印张数

输出

总的打印次数和打印张数

提示

代码如下


#include <iostream>
using namespace std;
class FastPrinter
{
public:
    FastPrinter() {}
    FastPrinter(int year,int month,int day,int num);
    ~FastPrinter() {}
    void PrintJob() {}
    static unsigned int getcounts()
    {
        return counts;
    }
    static unsigned int gettotals()
    {
        return totals;
    }
private:
    static unsigned int counts;
    static unsigned int totals;
    int year,month,day;
};
unsigned int FastPrinter::counts = 0;
unsigned int FastPrinter::totals= 0;
FastPrinter::FastPrinter(int year,int month,int day,int num):year(year),month(month),day(day)
{
    totals=totals+num;
    counts++;
}
int main()
{
    FastPrinter *fp;
    int year,month,day,num;
    int n,m;
    cin>>n;
    while(n--)
    {
        cin>>m;
        while(m--)
        {
            cin>>year>>month>>day>>num;
            fp=new FastPrinter(year,month,day,num);
            fp->PrintJob();
            delete fp;
        }
    }
    cout<<"打印次数:"<<FastPrinter::getcounts()<<",张数:"<<FastPrinter::gettotals()<<endl;
    return 0;
}
