C++ Program to Calculate Average Percentage Marks

Calculate Average and Percentage Marks of Student in C++

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 (5 subjects here).

Place summation of 5 subject's marks in a variable say sum and place sum/5 in a variable say avg (average of 5 subjects) then place sum/500*100 in a variable say perc (percentage marks), then display the result on the screen as shown here in the following program.

C++ Programming Code to Calculate Average Percentage Marks

Following C++ program ask to the user to enter the marks obtained in 5 subjects to calculate and display the average and percentage marks :

/* C++ Program - Calculate Average and Percentage Marks */
		
#include<iostream.h>
#include<conio.h>
void main()
{
	clrscr();
	int mark[5], i;
	float sum=0;
	cout<<"Enter marks obtained in Physics, Chemistry, Maths, CS, English :";
	for(i=0; i<5; i++)
	{
		cin>>mark[i];
		sum=sum+mark[i];
	}
	float avg=sum/5;
	float perc;
	perc=(sum/500)*100;
	cout<<"Average Marks = "<<avg;
	cout<<"\nPercentage = "<<perc<<"%";
	getch();
}

When the above C++ program is compile and executed, it will produce the following result:
