PART A
1. Write a Program that implements Date and Time Functions.
ANS:-
using System;namespace ConsoleApplication1{
class b{
static void Main(string[] args){
DateTime dt = DateTime.dt;Console.WriteLine("the data and time is : {0}", now);Console.ReadLine();
}}
}
OUTPUT
The date and time is : 9/25/2010 8:22:12 PM
2 Write a Program to check whether a string is palindrome or not.
ANS:-
using System;
namespace ConsoleApplication2{
class c{
static void Main(string[] args)
{ string s = string.Empty;
Console.WriteLine("Enter String here");
string s1 = Console.ReadLine();
int i = s1.Length;

for (int j = i - 1; j >= 0; j--){
s = s + s[j];}
if (s == s1)
{
Console.WriteLine("This srting is Palindrome");
}
else{
Console.WriteLine("this string is Not a palindeome");}
Console.WriteLine(s);
Console.Read();
}}
}
Output:Enter String hereGauravthis string is Not a palindeome

r1.l=50;r2.w=60;a1=r1.l*r2.w;ad1 = r1.l + r2.w;s1 = r2.w - r1.l;div1 = r2.w / r1.l;Console.WriteLine("the Substract (60 and 50)is------->" + s1);Console.WriteLine("Additition (60 and 50)is------->" + ad1);Console.WriteLine("Areamet (50 and 60) is ------->"+a1);Console.WriteLine("Division (60 and 50)is ------->" + div1);Console.ReadLine();
}}
}
5 Write a program to compute sum of all the elements stored in a single dimension array using
functions.
ANS:-
using System;
namespace ConsoleApplication1{
class m{
Assignment 2 Page 5

http://slidepdf.com/reader/full/2c-sharp 6/10
static void Main(string[] args){
int[] a = new int[10];int i, b,y=0;Console.WriteLine("the size of array is");
i = Convert.ToInt32(Console.ReadLine());Console.WriteLine("the elements of array enter here");for (b = 1; b <= i; b++){
a[b] = Convert.ToInt32(Console.ReadLine());y = y + a[b];
}Console.WriteLine("sum of array "+y);Console.ReadLine();
}
}}
PART B
1. Write a program with functions to find the factorial of a number using recursion.
ANS:-
using System;
namespace fact{
class l{
static void Main(string[] args){
int i;Console.WriteLine("Enter the number for factorial");
i = Convert.ToInt32(Console.ReadLine());
long a=Factorial(i);Console.WriteLine("the Factorial of the number is---->"+a);Console.ReadLine();
}static long Factorial(long number)
{if (number <= 1)

return 1;else
return number * Factorial(number - 1);}
}
}
2. Create a class using methods to store and print general information of a customer.
ANS:-
using System;
namespace ConsoleApplication1{
class P{
class o{
public void str(){
int b;string a = "";
Console.WriteLine("here Customer name ?");
a = Console.ReadLine();Console.WriteLine("the items ?");int i = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("cost=10 rs/per item:");b = i * 10;
Console.WriteLine("CUSTOMER name" + a);Console.WriteLine("");Console.WriteLine("ttl cost”+ b);
}
};static void Main(string[] a){
o oo = new o();

oo.str();Console.ReadLine();
}
}}
3. Write a program with multiple classes to show the reusability of code.

using System;
namespace ConsoleApplication1{
class P{
class roomcls{
public int l;public int b;public roomcls(int x, int y){
l = x;b = y;
}public int ar(){
return (l * b);}

bedroomcls roomcls1 = new bedroomcls(14, 12, 10);int ar1 = roomcls1.ar();int vol1 = roomcls1.vol();Console.WriteLine("Ar1=" + ar1);Console.WriteLine("Vol1=" + vol1);Console.ReadLine();
}
}}
}
4. Write down various access identifiers used in C#.
ANS:-
public - The member can be accessed from anywhereinternal - The member can only be accessed from type it originates from or other types in the same assembly
protected - The member can only be accessed from the type it originates from or from detrieved types of the
originating type protected internal - implies protected OR internal ( not protected AND internal )
private - The member is only accessible by other members within the type it originates from.
5. Can you inherit from multiple classes in C#? If yes then justify your answer by giving suitable
example and if no then give reason .
ANS:- “ We can not inherit from multiple classes in C#. But, it can possible by multiple interfaces. ”
Example:-
using system;
namespace consoleapplication1{
class p{
interface addition{int addition();
}interface multipl{
int multipl();}
Assignment 2 Page 9

http://slidepdf.com/reader/full/2c-sharp 10/10
class calcul : addition, multipl{
int x, y;public calcul(int x, int y){
this.x = x;this.y = y;
}public int a(){
return (x + y);}public int m(){
return (x * y);}
}
class in{
public void main(string[] args){
calcul com = new calcul(10, 20);addition object1 = (addition)com;console.writeline("the sum=" + object1.a());multipl object2 = (multipl)com;console.writeline("the product=" + object2.multipl());
console.readline();
}}
