how to arrange array in ascending order in c++

#include <iostream>
using namespace std;

#define MAX 100

int main()
{
	//array declaration
	int arr[MAX];
	int n,i,j;
	int temp;
	
	//read total number of elements to read
	cout<<"Enter total number of elements to read: ";
	cin>>n;
	
	//check bound
	if(n<0 || n>MAX)
	{
		cout<<"Input valid range!!!"<<endl;
		return -1;
	}
	
	//read n elements
	for(i=0;i<n;i++)
	{
		cout<<"Enter element ["<<i+1<<"] ";
		cin>>arr[i];
	}
	
	//print input elements
	cout<<"Unsorted Array elements:"<<endl;
	for(i=0;i<n;i++)
		cout<<arr[i]<<"t";
	cout<<endl;
	
	//sorting - ASCENDING ORDER
	for(i=0;i<n;i++)
	{		
		for(j=i+1;j<n;j++)
		{
			if(arr[i]>arr[j])
			{
				temp  =arr[i];
				arr[i]=arr[j];
				arr[j]=temp;
			}
		}
	}
	
	//print sorted array elements
	cout<<"Sorted (Ascending Order) Array elements:"<<endl;
	for(i=0;i<n;i++)
		cout<<arr[i]<<"t";
	cout<<endl;	
	
	
	return 0;

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;
