# Java Program For Calculate Percentage Of 5 Subjects

Problem:- Java Program For Calculate Total Marks Of 5 Subjects And percentage.means yo have to give a variable size of a subject like 2,3,5 and more subject as the user wants and you need to calculate the percentage of marks and also print the marks of each subject.

Check This:- Hacker rank solution for Strings, Classes, STL, Inheritance in C++.

Logic:- First we will ask the user for the total number of the subject after that we will enter marks of all those subjects. Now we will calculate a percentage of marks and print student marks, percentage, and Grade of Student. Percentage formula is given Below.

Check This:- Hacker rank solution for Strings, Classes, STL, Inheritance in C++.

Percentage of Marks = (all subject marks sum) / Total Subject *100.

Explanation:- For this problem, I am taking 5 subjects. Now first user enter number of the subject of a student after that enter all subject marks and store the marks in an array, see the below part of the code.

printf("\nEnter number of subject : \n");
scanf("%d", &n);

for(i=0;i<n;i++)
{
scanf("%d", &arr[i]);
}

Now next step to add or a sum of all subjects marks entered by the user.

for(i=0;i<n;i++)
{
sum=sum+arr[i];
}

Now apply the formula and print the output calculated by the formula given.

Percentage = ( sum * 100 ) / tmp;

printf("\nPercentage Of Student : %d\n", Percentage);

here tmp is a number of subject * 100.

Example:- Now take an example and check the output step by step. let's take 6 subjects in a semester and we have to calculate percentage out of total number 6 * 100 = 600.

Enter number of subjects: 6 // 6 is user input

Enter The Marks: 78 65 56 89 45 90

Percentage of a student: 70.5

import java.util.Scanner;

public class percentage
{
public static void main(String args[])
{
int marks[] = new int[5];
int i;
float per,sum=0;

Scanner sc = new Scanner(System.in);

System.out.print("Enter The 5 Subject Marks : ");
for(i=0; i<5; i++)
{
marks[i] = sc.nextInt();
sum = sum + marks[i];
}

per = (sum/500) * 100;

System.out.print("\nStudent Percentage is = " +per+ "%\n\n");
}
}

Output:-
