how to sort integer array numbers/elements 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;
 
}
