Hello friends! Welcome to my website

Today we run C++ programming to find out the grade of a student when the marks of 6 subjects are given.
The method of assigning grade is –
percentage>=85       grade=A
percentage<85  and percentage>=70 grade=B
percentage<70  and percentage>=55 grade=C
percentage<55  and percentage>=40 grade=D
percentage<40      grade=E

This c++ language programming is free all type of errors like the compiler and runtime errors and this programming is tested to compile and then run the program code.
Here is only programming code with the output. This programming output is customized to understand easily.

Find grade of a student according to their percentage in c++ programming

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

class test2 {
public:
    double m1, m2, m3, m4, m5, m6;
    string grade, name;
     void Getgrade(double m1,double m2,double m3,double m4,double m5,double m6,string grade,string name) {
        double pre, total;
//total Maarks of all subject
        total = m1 + m2 + m3 + m4 + m5 + m6;
        pre = total / 6;
        if (pre > 33) {
            if (pre >= 85) {
                grade = “A”;
                cout<<name<<” passed with “<<grade<<” Grade and “<<pre<<“%”;
            }
            else if (pre >= 70) {
                grade = “B”;
                cout<<name<<” passed with “<<grade<<” Grade and “<<pre<<“%”;
            }
            else if (pre >= 55) {
                grade = “C”;
                cout<<name<<” passed with “<<grade<<” Grade and “<<pre<<“%”;
            }
            else if (pre >= 40) {
                grade = “D”;
                cout<<name<<” passed with “<<grade<<” Grade and “<<pre<<“%”;
            }
            else {
                grade = “E”;
                cout<<name<<” passed with “<<grade<<” Grade and “<<pre<<“%”;
            }
        }
        else {
             cout<name<<” is fail in  exam, Score only “<<pre<<“%”;
        }
    }
}

int main(){
test2 o ;
     cout<<“Please Enter the Student Name:”;
     o.name = c.nextLine();
     cout<<“enter all the marks of “<<o.name<<“:”);
     cin>>o.m1;
     cin>>o.m2;
     cin>>o.m3;
     cin>>o.m4;
     cin>>o.m5;
     cin>>o.m6;
     o.Getgrade(o.m1,o.m2,o.m3,o.m4,o.m5,o.m6,o.grade,o.name);
}

Output:
     Please Enter the Student Name:Abcd
enter all the marks of Abcd: 75
74
45
89
100
99
Abcd passed with B Grade and 80.33333333333333%
