C++11 Initializer Lists :part 2
Iterating through Initializer Lists can be done in a few different ways:
- Using for loops: You can use a for loop to iterate through an Initializer List by treating it as an array. For example, to iterate through an Initializer List of integers:
int myArray[] = {1, 2, 3, 4, 5};
for (int i = 0; i < 5; i++) {
std::cout << myArray[i] << " ";
}
- Using range-based for loops: C++11 introduced the range-based for loop, which allows for easy iteration through an Initializer List. For example, to iterate through an Initializer List of integers:
int myArray[] = {1, 2, 3, 4, 5};
for (int i : myArray) {
std::cout << i << " ";
}
- Using iterators: You can also use iterators to iterate through an Initializer List. For example, to iterate through an Initializer List of integers:
int myArray[] = {1, 2, 3, 4, 5};
for (auto i = std::begin(myArray); i != std::end(myArray); i++) {
std::cout << *i << " ";
}
It's worth noting that the range-based for loop and the iterator-based approach work with Initializer Lists of any type, while the for loop approach works only with arrays, it's not recommended to use it with initializer lists.
Overall, Initializer Lists can be iterated through using for loops, range-based for loops, and iterators. The range-based for loop and the iterator-based approach provide a more versatile and flexible way to iterate through Initializer Lists, while the for loop approach is more limited but can be useful when working with arrays.
