Question:How to reduce the spaces between words.

I want to know how to reduce the spaces between words if they are separated by more than one spaces.
I know a little bit of it.After Scanning the string to see if a space is encountered,what am i supposed to do?

You could use something like (pseudocode):

Code:

---

bool last_character_was_a_space = false;
for-each-character {
  if char == space {
      if last_character_was_a_space {
        remove_character;
      } else {
        keep_character;
        last_character_was_a_space = true;
      }
  } else {
      keep_character;
      last_character_was_a_space = false;
  }
}

---

The simplest way to handle the removing is to just append the characters you want to keep to a new string:

Code:

---

std::string result;
  ...
    //keep_character
    result += char;
