I have this code snippet from online.
void ShortenSpace(string &s) { // n is length of the original string int n = s.length(); //pointer i to keep trackof next position and j to traverse int i = 0, j = -1; // flag that sets to true is space is found bool spaceFound = false; // Handles leading spaces while (++j < n && s[j] == ' '); // read all characters of original string while (j < n) { // if current characters is non-space if (s[j] != ' ') { //if any preceeding space before ,.and ? if ((s[j] == '.' || s[j] == ',' || s[j] == '?') && i - 1 >= 0 && s[i - 1] == ' ') s[i - 1] = s[j++]; else // copy current character to index i // and increment both i and j s[i++] = s[j++]; // set space flag to false when any // non-space character is found spaceFound = false; } // if current character is a space else if (s[j++] == ' ') { // If space is seen first time after a word if (!spaceFound) { s[i++] = ' '; spaceFound = true; } } } // Remove trailing spaces if (i <= 1) s.erase(s.begin() + i, s.end()); else s.erase(s.begin() + i - 1, s.end()); } The problem is if the input is: "test (multiple spaces) test (multiple spaces) test."
It will remove the last period and put output like "test test test"
It removes the whitespace correctly but somehow it is mishandling/removing the punctuation. I do not want it to remove the punctuation. I'm still beginner in C++ so I am having a hard time figuring out why.
