Sort an array without algorithm

#include <iostream>

#include <algorithm>

int main() {

int array[] = { 23, 5, -10, 0, 0, 321, 1, 2, 99, 30 };

int elements = sizeof(array) / sizeof(array[0]);

std::sort(array, array + elements);

for (int i = 0; i < elements; ++i)

std::cout << array[i] << ' ';

}

//The same functionality using vector container:


#include <iostream>

#include <algorithm>

#include <vector>

int main() {

std::vector<int> vec {10, 5, 100};

std::sort(vec.begin(), vec.end());

for (int i = 0; i < vec.size(); ++i)

std::cout << vec[i] << ' ';

}
