C++ 程序查找学生成绩

编写一个C++程序，根据学生的分数查找学生成绩。下面的C++程序允许用户输入五个不同科目的分数。接下来，我们将计算这五门科目的总分、平均分和百分比。根据百分比，我们将打印出学生的成绩。

#include<iostream>

using namespace std;

int main()
{
	int english, chemistry, computers, physics, maths; 
    float total, average, percentage;

    cout << "Please Enter the marks of five subjects: \n";
    cin >> english >> chemistry >> computers >> physics >> maths;

    total = english + chemistry + computers + physics + maths;
    average = total / 5;
    percentage = (total / (500)) * 100;

    cout << "\nTotal Marks      = " << total;
    cout << "\nAverage Marks    = " << average;
    cout << "\nMarks Percentage = " << percentage;
    
    if(percentage >= 90)    {
    	cout << "\nGrade A";
	}
	else if(percentage >= 80)    {
    	cout << "\nGrade B";
	}
	else if(percentage >= 70)    {
    	cout << "\nGrade C";
	}
	else if(percentage >= 60)    {
    	cout << "\nGrade D";
	}
	else if(percentage >= 40)    {
    	cout << "\nGrade E";
	}
	else {
    	cout << "\nFail";
	} 
	
 	return 0;
}
