C + + Removes the leading and trailing spaces and all spaces in a string

C + + Remove the first and last space is a reference to an article, but forget the article source, just skip it.

The code to remove the trailing spaces is as follows:

void Trim (String &s) {    if (!s.empty ())    {        s.erase (0,s.find_first_not_of (""));        S.erase (S.find_last_not_of ("") + 1);}    } Remove the leading and trailing spaces

　　

The code for removing all the spaces in the string is as follows:

void Trim (string &s) {/    *    if (!s.empty ())    {        s.erase (0,s.find_first_not_of (""));        S.erase (S.find_last_not_of ("") + 1);    }    */    int index = 0;    if (!s.empty ())    {        while (index = S.find (', index))! = String::npos)        {            s.erase (index,1);        }    }} Remove all spaces

　　

The test code is as follows:

int main () {       cout << "-------------------------------------" << Endl;    String pri = "  7ter   , jdhfd iere*-ddw     jjdjjdj     ";    cout << "private string is: \" "<< pri <<" \ "" << Endl;    Trim (PRI);    cout << "After string is: \" "<< pri <<" \ "" << Endl;    cout << "-------------------------------------" << Endl;    return 0;} Test code
