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:
