C++ Program to Calculate Grade of Student

In this example, you will learn to calculate grade of a student. The user will ask to enter marks obtained in 5 subjects and calculate obtained grade of that student using if…else statement.

Example: Program to Calculate Grade of Student

#include <iostream>
using namespace std;
int main()
{
    int mark[5], i;
    float sum=0,avg;
    cout<<"Enter marks obtained in 5 subjects :" << endl;
    for(i = 0; i < 5; i++)
    {
        cin >> mark[i];
        sum = sum + mark[i];
    }
    avg = sum / 5;
    cout << "Your Grade is ";
    if(avg > 80)
    {
        cout << "A";
    }
    else if(avg > 60 && avg <= 80)
    {
        cout << "B";
    }
    else if(avg > 40 && avg <= 60)
    {
        cout << "C";
    }
    else
    {
        cout << "D";
    }
    return 0;
}

#include <iostream>

using namespace std;

int main()

{

int mark[5], i;

float sum=0,avg;

cout<<"Enter marks obtained in 5 subjects :" << endl;

for(i = 0; i < 5; i++)

{

cin >> mark[i];

sum = sum + mark[i];

}

avg = sum / 5;

cout << "Your Grade is ";

if(avg > 80)

{

cout << "A";

}

else if(avg > 60 && avg <= 80)

{

cout << "B";

}

else if(avg > 40 && avg <= 60)

{

cout << "C";

}

else

{

cout << "D";

}

return 0;

}

When you run the program, the output will be following:

Enter marks obtained in 5 subjects :
85
38
67
82
50
Your Grade is B

Enter marks obtained in 5 subjects :

Your Grade is B
