ReplyDeleteThe difference is that static read-only can be modified by the containing class, but const can never be modified and must be initialized to a compile time constant. To expand on the static read-only case a bit, the containing class can only modify it:
ReplyDelete-- in the variable declaration (through a variable initializer).
-- in the static constructor (instance constructors if it's not static).
Can we assign the Null value to the Struct variable
ReplyDeleteIf you wanna do so-you can use Nullable.
4.Can we assign the Null value to the Struct variable ? Justify your Answer
ReplyDeleteStruct is always value type:
If you wanna do so you can use Nullable
5.Write a Program to get Output
ReplyDeleteGiven I/P :"Subhash is a nice guy";
O/P :"guy nice a is subhash";
using System;
namespace ReverseWords
{
class Program
{
static void Main(string[] args)
{
string original =
“But, in a larger sense, we can not dedicate--we can
➥not consecrate--we can not hallow--this ground.”;
Console.WriteLine(“Original: “ + original);
Console.WriteLine(“Reversed: “ + ReverseWords(original));
Console.ReadKey();
}
static string ReverseWords(string original)
{
//first convert the string to a character array since
//we’ll be needing to modify it extensively.
char[] chars = original.ToCharArray();
ReverseCharArray(chars, 0, chars.Length - 1);
//now find consecutive characters and
//reverse each group individually
int wordStart = 0;
while (wordStart < chars.Length)
{
//skip past non-letters
while (wordStart < chars.Length-1 &&
!char.IsLetter(chars[wordStart]))
wordStart++;
//find end of letters
int wordEnd = wordStart;
while (wordEnd < chars.Length-1 &&
char.IsLetter(chars[wordEnd+1]))
wordEnd++;
//reverse this range
if (wordEnd > wordStart)
{
ReverseCharArray(chars, wordStart, wordEnd);
}
wordStart = wordEnd + 1;
}
return new string(chars);
}
static void ReverseCharArray(char[] chars, int left, int right)
{
int l = left, r = right;
while (l < r)
{
char temp = chars[l];
chars[l] = chars[r];
chars[r] = temp;
l++;
r--;
}
}
}
}
Source-C# 4.0 How to
Write a Program to get Output
ReplyDeleteGiven I/P :"Subhash is a nice guy";
O/P :"guy nice a is subhash";
Here we go:
public static string ReverseWords(string sentence)
{
string[] words = sentence.Split(' ');
Array.Reverse(words);
return string.Join(" ", words);
}
how about this:
ReplyDeletestring s = "apple boll cat dog elephant";
string[] ss = s.Split(' '); s = ss[ss.Length-1].ToString();
for (int i = 1; i <= ss.Length-2; i++)
{
s = s + " "+ ss[i].ToString();
}
s = s + " "+ss[0].ToString();
Console.WriteLine(s);
Console.ReadLine();
