How to sort and array with integers in c++/
LETS SAY int arr[5]={1,2,3,4,5};

[TwilightSpectre]

#include <algorithm>
#include <iostream>

int main() {
    const int size = 5;
    int arr[size] = {1, 3, 2, 5, 4};

    std::sort(arr, arr + size);

    for (int i = 0; i < size; ++i) 
        std::cout << arr[i] << ' ';

    return 0;
}

Easiest way to sort something in C++ is to use std::sort.

#include <algorithm>
#include <iterator>

int main()
{
	int arr[5]={1,2,3,4,5};
	std::sort(std::begin(arr), std::end(arr));
}
