char s[] = "how are     you";
	int n = strlen(s);
	int i=0;
	while(s[i] != '\0')
	{
		if(s[i] == ' ')
			s[i] = 7; // ascii for bell
		i++;
	}
	cout << s << endl;

How about we fill the white spaces with null character('\0') and concatenate the sub strings.. plzz comment

class string // Just deleting character
{
public static void main(String[] args)
{
String x="teja is a good boy";
x=x.replaceAll(" ","");
System.out.println(x);
}
}

I think in place and without shifting is not possible together...any clues?

std::string remBlank(std::string input){
std::string newstring;
for(int i=0;i<input.length();i++){
if(input.at(i)==32){
newstring+="%20"; }
else{newstring+=input.at(i);} }
return newstring;}

What about this code.... correct me if i am wrong...!!
int main()
{
char s[] = "how are you friends";
int i=0;
while(s[i] != '\0')
{
if(s[i] == ' ' && s[i+1]==' ')
{ s[i+1] = '\b'; i++; }
else if(s[i]== ' ') s[i]='\a';
i++;
}
printf("%s\n", s);
}

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string str = "how are you";
int n = str.Length;
int i=0;

char[] s = str.ToCharArray();

Console.WriteLine("Original string : " + str);
for (i = 0; i < n; i++)
{
if (s[i] == ' ')
s[i] = '\a'; // ascii for bell

}

Console.Write("String w/o space : ");
for (i = 0; i < n; i++)
Console.Write(s[i]);

Console.Read();
}
}
}

public static void removeSpace(char[] string) {
		if (string == null || string.length == 0) {
			return;
		}

		int p1 = 0;
		int p2 = 0;

		do {
			while (p2 < string.length && string[p2] == ' ') {
				p2++;
			}
			if (p2 == string.length) {
				break;
			}
			string[p1++] = string[p2++];
		} while (p1 < string.length && p2 < string.length);

		for (int p = p1; p < string.length; p++) {
			string[p] = 0;
		}

		for (char c : string) {
			System.out.print(c + " ");
		}
		
		System.out.println();
	}

fun(char *a)
{
for(i=j=0;a[i];i++)
if(a[i]!=' ')a[j++]=a[i];
a[j]='\0';
}
