bubble sort cpp 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++ template

// template <class t>
// void bubble <t>::sort(int n)
template < typename T > void bubble_sort( T a[], int n )
{
    int i,j;
    //t temp;
    T temp ;
    for(i=0; i<n; i++)
    {
        for(j=i+1; j<n; j++)
        {
            if(a[i]>a[j]) //bubble sort algo
            {
                temp=a[i];
                a[i]=a[j];
                a[j]=temp;
            }
        }
    }
}

Example 3: code for bubble sort in c++

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