三科平均分最高的学生

给定一个包含学生姓名和他/她在 3 个科目中得分的数据的文件。任务是找到平均分最高的学生列表。
注意：如果超过一名学生的平均分最高，请按照文件中的顺序打印。
例子：

Input : file[] = {“Shrikanth”, “20”, “30”, “10”, “Ram”, “100”, “50”, “10”} 
Output : Ram 53 
Average scores of Shrikanth, Ram are 20 and 53 respectively. So Ram has the maximum average score of 53. 
Input : file[] = {“Ramesh”, “90”, “70”, “40”, “Adam”, “50”, “10”, 
            ”40″, “Suresh”, “22”, “1”, “56”, “Rocky”, “100”, “90”, “10”} 
Output : Ramesh Rocky 66 
Average scores of Ramesh, Adam, Suresh and Rocky are 66, 33, 26 and 66 respectively. So both Ramesh and Rocky have the maximum average score of 66. 
 

方法 ：

1. 遍历文件数据并存储每个学生的平均分数。
2. 现在，找到最高平均分并搜索所有具有该最高平均分的学生。
3. 按照文件中的顺序打印最高平均分和姓名。

下面是上述方法的实现：

C++

// C++ program to find the
// list of students having maximum average score
#include
using namespace std;
 
// Function to find the
// list of students having maximum average score
// Driver code
void getStudentsList(string file[],int n)
{
    // Variables to store average score of a student
    // and maximum average score
    int avgScore;
    int maxAvgScore = INT_MIN;
 
    // List to store names of students
    // having maximum average score
    vector names;
 
    // Traversing the file data
    for (int i = 0; i < n; i += 4) {
 
        // finding average score of a student
        avgScore = (stoi(file[i + 1]) +
                    stoi(file[i + 2]) +
                stoi(file[i + 3])) / 3;
 
        if (avgScore > maxAvgScore) {
            maxAvgScore = avgScore;
 
            // Clear the list and add name of student
            // having current maximum average score in the list
            names.clear();
            names.push_back(file[i]);
        }
 
        else if (avgScore == maxAvgScore)
            names.push_back(file[i]);
    }
 
    // Printing the maximum average score and names
    // of students having this maximum average score
    // as per the order in the file.
    for (int i = 0; i < names.size(); i++) {
        cout <
