Question 1:- write a program that should accept two numbers from the users and perform the following mathematical operation-
v Addition
v Subtraction
v Multiplication
v Division
Answer :-
class Program
{
int num1, num2, result;
char ch;
public void accept()
{
Console.WriteLine("Main menu");
Console.WriteLine("1:- addition");
Console.WriteLine("2:- subtraction");
Console.WriteLine("3:- Multiplication");
Console.WriteLine("4:- division");
Console.WriteLine("pleasee enter our choicee");
Ch = Convert.ToChar(Console.ReadLine());
}
public void display()
{
Console.WriteLine("enter the first number");
num1 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("enter the second number");
num2 = Convert.ToInt32(Console.ReadLine());
}
public void output()
{
switch (ch)
{
case '1':
{
result = num1 + num2;
Console.WriteLine("result=" + result);
break;
}
case '2':
{
result = num1 - num2;
Console.WriteLine("result=" + result);
break;
}
case '3':
{
result = num1 * num2;
Console.WriteLine("result=" + result);
break;
}
case '4':
{
result = num1 / num2;
Console.WriteLine("result=" + result);
break;
}
default:
{
Console.WriteLine("invalid choice");
break;
}
}
}
static void Main(string[] args)
{
Program cal = new Program();
cal.accept();
cal.display();
cal.output();
Console.ReadLine();
}
}
Question 2:- write a program to identify the largest of three numbers enter by user. Create a program using methods.
Answer :-
class Program
{
int num1, num2, num3;
public void accept()
{
Console.WriteLine("enter the first number");
num1 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("enter the second number");
num2 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("enter the third number");
num3 = Convert.ToInt32(Console.ReadLine());
}
public void display()
{
if(num1>num2 && num1>num3)
{
Console.WriteLine("first number is largest"+num1);
}
else if(num2>num1 && num2>num3)
{
Console.WriteLine("second number is largest"+num2);
}
else
{
Console.WriteLine("third number is largest"+num3);
}
}
static void Main(string[] args)
{
Program d = new Program();
d.accept();
d.display();
Console.ReadLine();
}
}
Question 3- predict the output of the following program-
class Program
{
int number;
public void square(int number)
{
Console.WriteLine("the numbeer is :{0}", number);
number *= number;
Console.WriteLine("the square of 10 is :{0}", number);
}
Program()
{
number=10;
square(number);
}
static void Main(string[] args)
{
Program cal = new Program();
Console.ReadLine();
}
}
Answer :-
The number is :10
The square of 10 is :100
Question 4:- predict the output of the following program-
class Program
{
static int number1;
public void display(int number)
{
Console.WriteLine(number);
}
Program()
{
number1++;
display(number1);
}
static Program()
{
number1 = 10;
number1++;
}
static void Main(string[] args)
{
Program cal1 = new Program();
Program cal2 = new Program();
Console.ReadLine();
}
}
Answer :- 12
13Question 5:- As a part of the team that is developing software for library, you have been assigned the task of writing a program, the program should accept the following book detail.
Ø Book number as int
Ø Book category (fiction or notification) as string
Ø Author name as string
Ø Number of copy available as int
Write the program to accept and display the preceding book details.
Answer :-
class Program
{
int book_number;
string book_categary;
string auther_naame;
int number_of_copy;
public void accept()
{
Console.WriteLine("enter the book number");
book_number = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("enter the bool categary");
book_categary = Console.ReadLine();
Console.WriteLine("enter the auther name");
auther_naame = Console.ReadLine();
Console.WriteLine("ente the number of copy");
number_of_copy = Convert.ToInt32(Console.ReadLine());
}
static void Main(string[] args)
{
Program d = new Program();
d.accept();
Console.ReadLine();
}
}
Question 6:- write the program that accept distance in kilometer, convert it into meter, and then display the result.
Answer :-
class Program
{
int distance, result;
public void accept()
{
Console.WriteLine("enter the distance in kilometer");
distance = Convert.ToInt32(Console.ReadLine());
}
public void display()
{
result = distance * 1000;
Console.WriteLine("after cinvert kilometer into meter" + result);
}
static void Main(string[] args)
{
Program d = new Program();
d.accept();
d.display();
Console.ReadLine();
}
}

Answer :-
class Program
{
static void Main(string[] args)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine("Congratulation! You Have Cleared Level.\n\n\tentring Leveel2.....?");
Console.ReadLine();
}}
