C++ vector sort

To sort a vector in C++, you can use the sort() function from the <algorithm> library. Here are the steps involved in sorting a vector using the sort() function:

  1. Include the necessary headers: cpp #include <vector> #include <algorithm> This allows you to use the vector and algorithm functions.

  2. Create a vector: cpp std::vector<int> numbers = {5, 2, 8, 3, 1}; This creates a vector called numbers and initializes it with some values.

  3. Sort the vector: cpp std::sort(numbers.begin(), numbers.end()); This line of code sorts the elements in the numbers vector in ascending order. The begin() and end() functions are used to specify the range of elements to be sorted.

  4. Print the sorted vector: cpp for (int num : numbers) { std::cout << num << " "; } This loop iterates over each element in the numbers vector and prints it. After sorting, the output will be in ascending order: 1 2 3 5 8.

That's it! Following these steps will allow you to sort a vector in C++ using the sort() function.
