c++ bubble sort code example

Example 1: bubble sort in c++

void bubble_sort( int A[ ], int n ) {
    int temp;
    for(int k = 0; k< n-1; k++) {
        // (n-k-1) is for ignoring comparisons of elements which have already been compared in earlier iterations

        for(int i = 0; i < n-k-1; i++) {
            if(A[ i ] > A[ i+1] ) {
                // here swapping of positions is being done.
                temp = A[ i ];
                A[ i ] = A[ i+1 ];
                A[ i + 1] = temp;
            }
        }
    }
}

Example 2: bubble sort c

#include  
using namespace std; 
  
void swap(int *xp, int *yp)  
{  
    int temp = *xp;  
    *xp = *yp;  
    *yp = temp;  
}  
  
// A function to implement bubble sort  
void bubbleSort(int arr[], int n)  
{  
    int i, j;  
    for (i = 0; i < n-1; i++)      
      
    // Last i elements are already in place  
    for (j = 0; j < n-i-1; j++)  
        if (arr[j] > arr[j+1])  
            swap(&arr[j], &arr[j+1]);  
}  
  
/* Function to print an array */
void printArray(int arr[], int size)  
{  
    int i;  
    for (i = 0; i < size; i++)  
        cout << arr[i] << " ";  
    cout << endl;  
}  
  
// Driver code  
int main()  
{  
    int arr[] = {64, 34, 25, 12, 22, 11, 90};  
    int n = sizeof(arr)/sizeof(arr[0]);  
    bubbleSort(arr, n);  
    cout<<"Sorted array: \n";  
    printArray(arr, n);  
    return 0;  
}

Example 3: bubble sort c++ template

// template 
// void bubble ::sort(int n)
template < typename T > void bubble_sort( T a[], int n )
{
    int i,j;
    //t temp;
    T temp ;
    for(i=0; ia[j]) //bubble sort algo
            {
                temp=a[i];
                a[i]=a[j];
                a[j]=temp;
            }
        }
    }
}

Example 4: code for bubble sort in c++

void bubbleSort (int S[ ],  int length) {
	bool isSorted = false;
	while(!isSorted)
   	{
		isSorted = true;
		for(int i = 0; i S[i+1])
           	     {
			int temp = S[i];
			S[i] = S[i+1];
     	       		S[i+1] = temp;
            		isSorted = false;
           	      }
      	}
      	length--;
}
}

Example 5: Bubble Sort C++

#include 

cout<<"\n Hello World ";
