QStringList fruits = {"apple", "banana", "orange"}; int numOfFruits = fruits.count(); // numOfFruits = 3
QStringList emptyList; int size = emptyList.count(); // size = 0In this example, we have created an empty QStringList named emptyList and called the count function to get the size of the list. Since the list is empty, the count function will return 0. To use QStringList in your code, you need to include the Qt library in your project. If you are using the Qt framework, the package library you need is already included. If you are using a different framework or IDE, you may need to install the Qt library separately.
