    }
    printf("\n\n= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =\n\n");
}

Output:

= = = = = Sort the Array elements in ascending order = = = = =

How many number you want to sort : 10
Enter the numbers in to the array :
5
3
6
4
8
1
10
2
9
7
The elements of the array are :
5    3    6    4    8    1    10    2    9    7   
The elements of the array after sorting :
1    2    3    4    5    6    7    8    9    10   

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
