Question

请帮助，如果我可以做一些更改，但仍然坚持显示输出最终成绩:(对不起，我没有发布确切的问题（现在我做了）。这是作业：老师需要输入成绩并获得最终成绩

#include<iostream>
#include<iomanip>
using namespace std;

double FinalGrade;
const int students=3;
const int grades=5;
void FillGrades(int[][grades],int,int);
void PrintGrades(int[][grades],int,int);
void GetFinal(int[][grades],int,int);

    int main()
    {
            double FinalGrade=0.0;
    int CSC212[students][grades];

    FillGrades(CSC212,students,grades);
    PrintGrades(CSC212,students,grades);
    double FinalValue[] = {0.05,0.1,0.2,0.25,0.4};
    GetFinal(CSC212,students,grades);


    system("pause");
    return 0;
}
void FillGrades(int setofgrades[][grades],int pupils,int tests)

Answer 1

尝试添加此行：

void GetFinal(int setofgrades[][grades],int pupils,int tests)
{
    for(int i=0;i<pupils;i++){
        for(int j=0;j<tests;j++)
            double FinalGrade=(setofgrades[i][j]*0.05)
                             +(setofgrades[i][j]*0.1)
                             +(setofgrades[i][j]*0.2)
                             +(setofgrades[i][j]*0.25)
                             +(setofgrades[i][j]*0.4);
/* --> */ cout << "Final grade: " << FinalGrade << "\n";
     }    
}

您没有显示最终成绩，因为没有输出语句显示最终成绩变量的内容。

我不确定你是否想在循环中使用cout。计算是针对每个循环执行的，但不会存储在任何地方。

循环内部看起来像：

    void GetFinal(int setofgrades[][grades],int pupils,int tests)
    {
        for(int i=0;i<pupils;i++){
            for(int j=0;j<tests;j++)
            {
                double FinalGrade=(setofgrades[i][j]*0.05)
                                 +(setofgrades[i][j]*0.1)
                                 +(setofgrades[i][j]*0.2)
                                 +(setofgrades[i][j]*0.25)
                                 +(setofgrades[i][j]*0.4);
    /* --> */ cout << "Final grade: " << FinalGrade << "\n";
            }
        }
}

Answer 2

我更改了一些代码，并添加了最终成绩计算的功能。有许多改进（从传递给函数的参数开始），但至少现在它可以工作。

$day = $timeCollection["mday"]; //day
$month = $timeCollection["mon"]; // month
$year = $timeCollection["year"]; // year
$hour = $timeCollection["hours"]; // hours
$minute = $timeCollection["minutes"]; // minutes
$seconds = $timeCollection["seconds"]; // seconds
