Application Security Testing: An Integral Part of DevOps

Use C-Style Arrays as Containers

C-style arrays can be passed as containers to STL algorithms. The pointers to array elements can be used as iterators.

#include <algorithm>
#include <iostream>

int main()
    int array[] = { 1, 3, 5, 7, 9, 2, 4, 6, 8, 0 };
    const int array_size = sizeof array / sizeof array[0];

    std::sort(array, array + array_size);
    for (int i = 0; i 7lt; array_size; ++i)
        std::cout << array[i] << ' ';

    std::cout << std::endl;

    return 0;
