# C++ Program To Arrange Numbers in Ascending Order Using Array Sorting

In ascending order, numbers are arranged from the smallest to the largest number. For example:

5     13     25     39     50     65     75     86     99     100

This C++ program to arrange numbers in ascending order is aimed to sort an array.

In this program, A user will input 5 random numbers in array and then program will arrange numbers in ascending order.

## C++ Source Code To Arrange Numbers in Ascending Order :

```#include<iostream>
#include<conio.h>
using namespace std;
void order(int arr[], int count);
int main()
{
int array[5];
cout << "Enter Array Elements (MAX 5) "<<endl;
cout<<"=============================="<<endl;
for (int i = 0; i < 5; i++)
{
cin >> array[i];
}
order(array, 5);
return 0;
}
void order(int arr[], int count)
{
int temp;
for (int i = 0; i < count; i++)
{
for (int j = i + 1; j < count; j++)
{
if (arr[i] > arr[j])
{
temp= arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
}
}
cout<<"=============================="<<endl;
cout <<"Ascending Order:";
for (int w = 0; w < count; w++)
{
cout << arr[w]<<" ";
}
}
```

## Code Explanation:

First of all we used the header files and the libraries which are going to be used in the given program.

Before diving into the function order , first we see our main()  function.

In main() function, we created an array of 5 elements and asked the user to enter numbers in array.

After receiving input from user, we passed this array to order function which arranges numbers in ascending order and displays them on screen.

We created a function order(int arr[] , int count) in which we will write the code to sort array elements in ascending order.

There are two parameters of order function:

1. First is denoted by arr[] and it is an array of integer type variables.

2. Second is count and it contains the length of array which is 5.

Then we defined an int type variable named temp. This will help us to swap the numbers which is core of this sorting technique.

Then we used FOR loop and introduced an integer and incremented it with 1 for each cycle.

Next we created nested FOR loop and introduced integer j with initial value i+1.

Inside loop, we used IF condition to compare whether the element at ith position is greater or the element at jth position.

If number at jth position is greater then it means that number is at its correct place.

If number at ith position is greater then we swap both numbers.

I highly recommend you to read this tutorial about swapping of two numbers.

After sorting the complete array using swapping , we are going to print numbers on screen.

We used FOR loop to display all the numbers on screen.

Finally your C++ program to arrange numbers is completed and now you can run your program and get the output.
