C++ (Cpp) stringList::size Examples

Programming Language: C++ (Cpp)

Class/Type: stringList

Method/Function: size

Examples at hotexamples.com: 4

The `size()` function in `StringList` class returns the number of elements in the list. Here are some examples showing how to use this function:

Example 1: Basic usage of size() function

#include 

int main()
{
    QStringList fruits = {"Apple", "Banana", "Cherry", "Date"};
    int count = fruits.size();  // Get number of elements
    return 0;
}

This example creates a `StringList` named `fruits` and fills it with four fruits. The `size()` function is used to get the number of fruits, which is stored in the `count` variable.

Example 2: Checking if list is empty

#include 

int main()
{
    QStringList names;
    bool isEmpty = names.isEmpty();  // Check if list is empty
    return 0;
}

This example creates an empty `StringList` named `names`. The `isEmpty()` function is used to check if the list is empty. If the list is empty, `isEmpty` variable will be `true`, otherwise it will be `false`. Package/library: `QtCore` from Qt framework.
