Last update on December 20 2024 12:48:16 (UTC/GMT +8 hours)

Write a C# Sharp program to read roll no, name and marks of three subjects and calculate the total, percentage and division.

Sample Solution:-

C# Sharp Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

public class Exercise12
{
    static void Main(string[] args)
    {
        // Declaration of variables for roll number, subject marks, total, percentage, name, and division
        double rl, phy, che, ca, total, per;
        string nm, div;

        // Displaying the purpose of the program
        Console.Write("\n\n");
        Console.Write("Calculate the total, percentage and division to take marks of three subjects:\n");
        Console.Write("-------------------------------------------------------------------------------");
        Console.Write("\n\n");

        // Prompting user to input roll number, name, and marks for three subjects (Physics, Chemistry, Computer Application)
        Console.Write("Input the Roll Number of the student :");
        rl = Convert.ToInt32(Console.ReadLine());

        Console.Write("Input the Name of the Student :");
        nm = Console.ReadLine();

        Console.Write("Input  the marks of Physics : ");
        phy = Convert.ToInt32(Console.ReadLine());
        Console.Write("Input  the marks of Chemistry : ");
        che = Convert.ToInt32(Console.ReadLine());
        Console.Write("Input  the marks of Computer Application : ");
        ca = Convert.ToInt32(Console.ReadLine());

        // Calculating total marks and percentage
        total = phy + che + ca;
        per = total / 3.0;

        // Determining division based on percentage achieved
        if (per >= 60)
            div = "First";
        else if (per < 60 && per >= 48)
            div = "Second";
        else if (per < 48 && per >= 36)
            div = "Pass";
        else
            div = "Fail";

        // Displaying student information, subject-wise marks, total, percentage, and division achieved
        Console.Write("\nRoll No : {0}\nName of Student : {1}\n", rl, nm);
        Console.Write("Marks in Physics : {0}\nMarks in Chemistry : {1}\nMarks in Computer Application : {2}\n", phy, che, ca);
        Console.Write("Total Marks = {0}\nPercentage = {1}\nDivision = {2}\n", total, per, div);
    }
}

Sample Output:

Calculate the total, percentage and division to take marks of three subjects:

Marks in Computer Application : 64                                                                            
Total Marks = 160                                                                                          
Percentage = 53.3333333333333                                                                                 
Division = Second
