Part I: Theoretical Questions (4 marks each) [20 Marks]

Convert the following Algebraic expression to C# equivalent?

p= m+ n + r + s+ y
6

y= ax2 + bx + c



Briefly explain the value data types and reference data types in C#.



Differentiate between while loop and do-while loop with the help of examples.



What is an exception? How exceptions are handled in C#? Briefly explain.


How multiple inheritance is implemented in C#? Demonstrate with the help of an example.



Part II: Output and Debugging Questions (10 marks each) [20 Marks]

Note: Provide a copy of the code and screen shot for the output in the solutions’

What is the output of the following program? [10 Marks]

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
int p;
int[] A = {2,5,6,1,8,4,9,1,3,0};
for (p = 0; p < 10; ++p)
{
if(A[p]%2 == 1)
Console.WriteLine(A[p]);

} Console.ReadLine();

}
}
}


What is the output of the following program? [6 Marks]

class Program
{
static void method1(ref int m, int n)
{
m = m + 10;
n = n + 20;
}

static void Main(string[] args)
{
int x = 100;
int y = 50;
method1(ref x, y);
Console.WriteLine("x =" + x);
Console.WriteLine("y =" + y);

Console.ReadLine();


}
}

Identify the errors in the following C# program. Write the correct program. [4 marks]

class Program
{
static Main(string[] args)
{
{
/ This is a comment
int m = 12
Console.WriteLine("The value of m = ",);
}
Console.ReadLine();
}
}








Part III- Problem Solving Questions [40 Marks]

Note: Provide a copy of the code and screen shot for the output in the solutions’

Write a C# program to print the factorial of a number input by the user. Hint: Factorial of number is the product of all positive integers less than or equal to that number. e.g. 5!= 5 X 4 X 3 X 2 X 1=120 [15 marks]
Sample I/O




Write a C# application that asks the user to input the required data to implement the four methods below:
(Use Method Overloading to write the methods)
Method Vol that takes as input, double values ‘r’ (radius) and ‘h’ (height), calculates the volume of a cone, and displays it. [Volume = 1/3 πr^2 h]

Method Vol that takes as input, double values ‘B’ (base area) and ‘h’ (height), calculates the volume of a pyramid, and displays it. [Volume = 1/3 Bh]

Method Vol that takes as input, a double value ‘r’ (radius), calculates the volume of a sphere, and displays it. [Volume = 4/3 πr^3]
[15 Marks]
Sample I/O





Using loops, write a C# program to print the following pattern. [10 Marks]
