Selection sort in C

Aim: Implement selection sort in C

#include <stdio.h> 
int main() 
{ 
    int arr[5], length = 5, i, j, temp,n,min;
	printf("Enter the number of elements : ");
	scanf("%d",&n);
	printf("Enter %d numbers : ",n);
    for (i = 0; i < n; i++)
	{
		scanf("%d",&arr[i]);
	}
    for (i = 0; i < n-1; i++) 
    { 
        min = i; 
        for (j = i+1; j < n; j++) 
          if (arr[j] < arr[min]) 
            min = j; 
  
        temp=arr[min];
        arr[min]=arr[i];
        arr[i]=temp;
    }
    printf("Sorted array is : ");
	for (i = 0; i < n; i++)
	{
        printf(" %d ",arr[i]);
	}
    return 0; 
} 

Output

Enter the number of elements : 5
Enter 5 numbers : 11 99 44 77 22   
Sorted array is :  11  22  44  77  99
