QStringList list; list << "apple" << "banana" << "apple" << "grapes"; int count = list.removeAll("apple"); // count = 2 // list = { "banana", "grapes" }
QStringList list; list << "red" << "green" << "blue" << "yellow"; int count = list.removeAll("orange"); // count = 0 // list = { "red", "green", "blue", "yellow" }In this example, we create a QStringList named 'list' with four elements. The removeAll function is then called with the argument "orange". Since that string is not present in the list, no elements are removed. The resulting list is unchanged. Package Library: The QString functions are part of the Qt library, which is a C++ cross-platform application development framework.
