计算一个学生在 N 个科目中获得的分数的 CGPA 和 CGPA 百分比

原文:https://www . geeksforgeeks . org/calculate-the-cgpa-and-cgpa-of-marks-由 n 科学生获得/

给定一个大小为 N 的数组 arr[] ，该数组包含学生在 N 个科目中的分数，任务是计算学生的 CGPA 和 CGPA 百分比。 注意:考虑每个科目的所有分数都在 100 分之外。

CGPA(累积绩点平均值)是教育流中获得平均绩点的系统安排。

示例:

输入: arr[] = {90，80，70，80，90} 输出: CGPA = 8.2，百分比= 77.89 说明: 各科成绩分别满分为 10 分{9，8，7，8，9}。 CGPA 是所有等级的平均值= (9 + 8 + 7 + 8 + 9) / 5 = 8.2 这个 CGPA 的百分比是 77.89。

输入: arr[] = {90，90，90，80，85} 输出: CGPA = 8.7，百分比= 82.65

方法:在本文中，CGPA 是按 10 分制计算的。

  • 从用户输入包含学生在 N 个科目中的分数的数组。
  • 因为分数是 10 分，所以把每门课的分数除以 10，就可以得到学生每门课的平均成绩。
  • 所有平均绩点的平均值产生学生的总平均绩点。
  • 找到 CGPA 后，CGPA 百分比可通过以下公式计算:
CGPA% = CGPA * 9.5
  • 这是 10 分制的通用公式。然而，如果整个计算是以 4 为尺度进行的，则 9.5 乘以 2.5 ，通过乘以 23.75 得到 CGPA 百分比。

下面是上述方法的实现:

C++

// C++ program to calculate the CGPA
// and CGPA percentage of a student
#include<bits/stdc++.h>
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);
}
