I want to remove blank space from a const string, but when i used remove function its showing error that const string cant modify.

const QString abc = "hello world";
QString def       = " ";
QString mk = abc .remove(def);  // Here error 开发者_开发问答saying const cant change

Please Help

You can't modify a const String. QString::remove returns a reference to abc, so remove works on abc, mk is not a copy but abc again!! Look for functions which are const functions if you want to operate on a const object.

EDIT:

const QString abc = "hello world";
QString ijk = abc;
QString def       = " ";
QString mk = ijk .remove(def);  // Here error saying const cant change

The same operation without additional variable:

const QString abc = "hello world";
QString def = " ";
QString mk = abc;
mk.remove(def);
