sorting inorder C++ code example

Example 1: how to sort an array in c++

#include <bits/stdc++.h> 
using namespace std; 

#define size(arr) sizeof(arr)/sizeof(arr[0]);


int main(){

    int a[5] = {5, 2, 6,3 ,5};
    int n = size(a);
    sort((a), a + n);
    for(int i = 0; i < n; i++){
        cout << a[i];
    }


    return 0;

}

#include <iostream>

10 for (string colour : colours){
11 cout << colour << ' ';
12 }
13 cout << endl;
14 sort(colours.begin(), colours.end());
