Write C# Program to find the eligibility for an engineering course based on the criteria.

I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability..

using System;
 
public class charpexercise
{
    public static void Main()
    {
        int p, c, m;
 
        Console.Write("\n\n");
        Console.Write("Find eligibility for admission :\n");
        Console.Write("----------------------------------");
        Console.Write("\n\n");
 
        Console.Write("Eligibility Criteria :\n");
        Console.Write("Marks in Maths >=65\n");
        Console.Write("and Marks in Phy >=55\n");
        Console.Write("and Marks in Chem>=50\n");
        Console.Write("and Total in all three subject >=180\n");
        Console.Write("or Total in Maths and Physics >=140\n");
        Console.Write("-------------------------------------\n");
 
 
        Console.Write("Input the marks obtained in Physics :");
        p = Convert.ToInt32(Console.ReadLine());
        Console.Write("Input the marks obtained in Chemistry :");
        c = Convert.ToInt32(Console.ReadLine());
        Console.Write("Input the marks obtained in Mathematics :");
        m = Convert.ToInt32(Console.ReadLine());
        Console.Write("Total marks of Maths, Physics and Chemistry : {0}\n", m + p + c);
        Console.Write("Total marks of Maths and  Physics : {0}\n", m + p);
 
        if (m >= 65)
            if (p >= 55)
                if (c >= 50)
                    if ((m + p + c) >= 180 || (m + p) >= 140)
                        Console.Write("The  candidate is eligible for admission.\n");
                    else
                        Console.Write("The candidate is not eligible.\n\n");
                else
                    Console.Write("The candidate is not eligible.\n\n");
            else
                Console.Write("The candidate is not eligible.\n\n");
        else
            Console.Write("The candidate is not eligible.\n\n");
 
        Console.ReadLine();
    }
}

Result:

Find eligibility for admission :

----------------------------------

Eligibility Criteria :

Marks in Maths >=65

and Marks in Phy >=55

and Marks in Chem>=50

and Total in all three subject >=180

or Total in Maths and Physics >=140

-------------------------------------

Input the marks obtained in Physics :85

Input the marks obtained in Chemistry :75

Input the marks obtained in Mathematics :65

Total marks of Maths, Physics and Chemistry : 225

Total marks of Maths and  Physics : 150

The  candidate is eligible for admission.
