HEAP SORT Data Structure Source Code Programming Algorithm Heap Sort

Heap sort there header file it contains following function void swap(int *x,int *y),void percdown(int A[],int i,int n),void display(int A[],int n),void heapsort(int A[],int n) by using these fucniton and data variable it will perform Heap sort algorithm.
