Average of 5 subjects and find percentage


Write a C++ Program to calculate Average of 5 subjects and find percentage. Here’s simple C++ Program to calculate Average of 5 subjects and find percentage in C++ Programming Language.


Numbers in C++


Normally, when we work with Numbers, we use primitive data types such as int, short, long, float and double, etc. The number data types, their possible values and number ranges have been explained while discussing C++ Data Types.


To calculate average and percentage marks of a student in C++ programming, you have to ask to the user to enter marks obtained in some number of subjects(n subjects).

Place summation of 5 subject’s marks in a variable say sum and place sum/n in a variable say avg (average of n subjects) then place sum/(n*100)*100 in a variable say perc (percentage marks), then display the result .


Here is source code of the C++ Program to calculate Average of 5 subjects and find percentage. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/* C++ Program to calculate Average of 5 subjects and find percentage  */

#include<iostream>
using namespace std;

int main()
{
        int mark[5], i;
        float sum=0;
        cout<<"\nEnter marks obtained in Physics, Chemistry, Maths, CS, English :: \n";
        for(i=0; i<5; i++)
        {
            cout<<"\nEnter mark[ "<<i+1<<" ] :: ";
                cin>>mark[i];
                sum=sum+mark[i];
        }

        float avg=sum/5;
        float perc;
        perc=(sum/500)*100;
        cout<<"\nAverage Marks of 5 Subjects = [ "<<avg<<" ] \n";
        cout<<"\nPercentage in 5 Subjects = [ "<<perc<<"% ] \n";

        return 0;
}

Output : :


/* C++ Program to calculate Average of 5 subjects and find percentage  */

Enter marks obtained in Physics, Chemistry, Maths, CS, English ::

Enter mark[ 1 ] :: 79

Enter mark[ 2 ] :: 87

Enter mark[ 3 ] :: 67

Enter mark[ 4 ] :: 99

Enter mark[ 5 ] :: 80

Average Marks of 5 Subjects = [ 82.4 ]

Percentage in 5 Subjects = [ 82.4% ]

Process returned 0

Above is the source code for C++ Program to calculate Average of 5 subjects and find percentage which is successfully compiled and run on Windows System.The Output of the program is shown above .
