how to print last word of any without breaking,last word should be print from next line

string input="Flat No-4324,Near Ganga Institute, Tehsil-Raipur, Distt-Banglore,State-Karnataka Pin-644487 India";

in the input string perhaps there are 96 character.

i want to make a program by which input.length always divided by 20(input.length/20)
and print,so in this case input will print in 5 line.In first line the last word is -Ganga(here in first line it will print-Flat No-4324,Near Ga)and the remaining again in 2nd line starting with- nga Institute.......(so here is problem)

i want that if the last letter length exceeded from length 20 then it should print from 2nd line,as i want then 1st line will be(Flat No-4324,Near ) then 2nd line start with Ganga Institute..... and if again this condition occur then so on .

If u r not getting so let's take below explanation--

i m saying that if,my every line length will be suppose 11 character,so there are some problem occur to print strings like this->( I want to play football and I want to play chess.)
1st line will take 11 character which will be(I want to p),in 2nd line will print(lay footbal) and so on.So here u can see play divide into 2 words p and lay,again football is dividing in 2 words footbal and l,so this is a problem.I want if this type of situation occur then complete word should be start from next line,as i want then 1st line will be(I want to) then 2nd line will be(play) and in 3rd line (football) and so on.

plz help

Not as easy as it sounds, but try this.

I wasn't sure whether you wanted to regard hyphen as a word character or not - I've assumed you do:

using System;

using System.Text.RegularExpressions;

class Program

{

static void Main()

{

string regExp = @"\b[-A-Za-z0-9_']+\b"; // regards A-Z a-z 0-9, underscore, hyphen and apostrophe to be word characters

string input = "Flat No-4324,Near Ganga Institute, Tehsil-Raipur, Distt-Banglore,State-Karnataka Pin-644487 India";

while(true)

{

Console.WriteLine("\nThe wrapped input is\n");

if (input.Length <= 20)

{

Console.WriteLine(input);

}

else

{

MatchCollection mc = Regex.Matches(input, regExp);

int first = 0;

int last = 19;

for(int i = 0; i < mc.Count; i++)

{

int index = mc[i].Index;

if (index == last + 1)

{

Console.WriteLine(input.Substring(first, last - first + 1));

first = last + 1;

}

else if (index == last + 2)

{

Console.WriteLine(input.Substring(first, last - first + 2));

first = last + 2;

}

else if (index > last + 2)

{

Console.WriteLine(input.Substring(first, mc[i - 1].Index - first));

first = mc[i - 1].Index;

}

else if (i == mc.Count - 1 && input.Length > last + 1)

{

Console.WriteLine(input.Substring(first, mc[i].Index - first));

first = mc[i].Index;

}

else

{

continue;

}

last = Math.Min(first + 19, input.Length - 1);

}

Console.WriteLine(input.Substring(first, last - first + 1));

}

Console.WriteLine("\nEnter string to wrap or q to quit\n");

input = Console.ReadLine();

if (input == "q" || input == "Q") return;

Console.WriteLine();

}

}

The output should be:

The wrapped input is

Flat No-4324,Near

Ganga Institute,

Tehsil-Raipur,

Distt-Banglore,

State-Karnataka

Pin-644487 India

Enter string to wrap or q to quit (etc)
