how to sort an array in c++ in ascending order code example

Example 1: c++ how to sort numbers in ascending order

// With the first loop we take a number of the array(x). 
    // With the second we take all the numbers in the array except x.
	// So we can compare each number with all the other numbers(9)

int arr[] = { 9, 8 , 3 , 5, 1, 2 , 0 , 4, 10,6 }; // System Input.
	for (int i = 0; i < 10; i++)     // For loop running array lenght times(10).
	{
		for (int j = i + 1; j < 10; j++) // For loop running 9 times(other nums).	
		{
			if (arr[i] > arr[j]) // Checking if current num(x) is larger than the next num(j).
			{
				
				int temp = arr[i]; // Storing current num(x)
				arr[i] = arr[j]; // Making i number equal to the next num(j).
				arr[j] = temp;  // Making the next number qeual to temp(i).
			}	
		}      	// SWITCHING PLACES WITH THE CURRENT AND THE NEXT NUM.
	}

	for (int i = 0; i < 10; i++)  // For loop running array lenght times(10).
	{
		cout << arr[i] << endl; // printing all the numbers!

	}

Example 2: 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;
