Sorting a vector
It’s a common requirement in software: organizing data. In C++, std::vector
is frequently the container of choice for many, and quite naturally, one would want to sort its elements. Enter the std::sort
algorithm, a versatile tool from the <algorithm>
header that elevates your std::vector
game to the next level.
Getting started with std::sort
std::sort
isn’t just for vectors; it can sort any sequential container. However, its symbiotic relationship with std::vector
is particularly noteworthy. At its simplest, using std::sort
to sort a vector is a straightforward task, as shown in the following code:
std::vector<int> numbers = {5, 1, 2, 4, 3}; std::sort(std::begin(numbers), std::end(numbers));
After execution, numbers
would store {1, 2, 3, 4, 5}
. The beauty lies in simplicity: pass the start and end iterators of the vector to std::sort
, and it takes care of the rest.
