计算学生在N个科目中获得的CGPA和CGPA分数

给定大小为N的数组arr [] ，该数组包含一个学生在N个科目中的成绩，则任务是计算该学生的CGPA和CGPA百分比。
注意：对于每个主题，请考虑所有分数均不超过100。

CGPA(Cumulative Grade Point Average) is the systematic arrangement in the educational stream to get an average of grade points.

例子：

Input: arr[] = {90, 80, 70, 80, 90} 
Output: CGPA = 8.2, Percentage = 77.89 
Explanation: 
The grade in each subject respectively out of 10 is {9, 8, 7, 8, 9}. 
The CGPA is the average of all the grades = (9 + 8 + 7 + 8 + 9) / 5 = 8.2 
The percentage of this CGPA is 77.89.

Input: arr[] = {90, 90, 90, 80, 85} 
Output: CGPA = 8.7, Percentage = 82.65

方法：在本文中，CGPA的计算范围为10。

• 从用户输入包含N个科目的学生成绩的数组。
• 由于比例尺为10，因此将每个学科的分数除以10，即可得出每个学科的学生的GPA。
• 所有GPA的平均值得出学生的总体CGPA。
• 找到CGPA之后，可以通过以下公式计算CGPA百分比：

CGPA% = CGPA * 9.5

• 这是刻度为10的一般公式。但是，如果整个计算是在刻度4上进行的，则此9.5将乘以2.5 ，而CGPA百分比将乘以23.75 。

下面是上述方法的实现：

C++

// C++ program to calculate the CGPA
// and CGPA percentage of a student
#include
using namespace std;
 
double CgpaCalc(double marks[], int n)
{
    // Variable to store the grades in
    // every subject
    double grade[n];
 
    // Variables to store CGPA and the
    // sum of all the grades
    double cgpa, sum = 0;
 
    // Computing the grades
    for(int i = 0; i < n; i++)
    {
       grade[i] = (marks[i] / 10);
    }
 
    // Computing the sum of grades
    for(int i = 0; i < n; i++)
    {
       sum += grade[i];
    }
 
    // Computing the CGPA
    cgpa = sum / n;
 
    return cgpa;
}
 
// Driver code
int main()
{
    int n = 5;
    double marks[] = { 90, 80, 70, 80, 90 };
 
    double cgpa = CgpaCalc(marks, n);
         
    cout << "CGPA = ";
    printf("%.1f\n", cgpa);
    cout << "CGPA Percentage = ";
    printf("%.2f", cgpa * 9.5);
}
