Stripping a string of spaces

How is this accomplished? I am using the string class ie

string test;

cin >> test; //they enter " This is a stri ng "

*stripping process*

//test now reads "Thisisastring"

If you must know I HAVE looked around for a few hours now and have attempted it myself multiple times; I am not just asking this without any effort

I'm not saying this is the best way to do this... I did an assignment like that a while ago and i used getline to input the string into an array. Then i just used a loop to copy every character that is not a space to a new array. Works fine. Don't forget the '\0' character at the end of the new string....

I tried this but it didn't work

Code:

---

string stripSpace(const string& infix){
        string strippedString;

        for (int i = 0; infix[i] != '\0'; i++){
                if (infix[i] != ' ')
                        strippedString += infix[i];
        }
        return strippedString;
}

I have never really worked with the string class before, so I can't really help you out there. If you want to use an array though, you could do it like this:

[code]

char rawinput[80];
char input[80];

cin.getline(rawinput, 80, '\n');

for(int i = 0, j = 0;;i++) {
if (rawinput[i] == ' ');
else{
input[j] = rawinput[i];
j++;
}
if (rawinput[i] == '\0') break;
}


[\code]

I can do it with arrays of chars but it's the string class that's baffling me

Sorry then, i am doing a hw assignment with strings right now, and i am a bit baffled myself...

thank you, though

Code:

---

string::iterator iter = test.begin();
string::iterator end = test.end();

while(iter != end)
{    if(*iter == ' ')
      {  test.erase(iter,iter+1);
      }
      iter++;
}

---

Code:

---

int main()
{
  string str = "blah blah blah";

  cout<<str<<endl;

  int x = str.find(" ");
  while(x < str.length())
  {
      str.replace(x, 1, "");
      x = str.find(" ", x + 1);
  }

  cout<<str<<endl;

  return 0;
}

I also realized something. I am not inputting my string correctly.

cin >> string; takes to the first space

cin.getline doesn't work

Ahhhh!

But BTW thanks you guys, that DOES work for removing whitespace

Thank all of you so much for the help!!
