C++ program to sort list of numbers using insertion sort algorithm.


C++ program to implement insertion sort

#include<iostream>
using namespace std;
class sort_list
{
    int data[20];
    int n;
public:
    void get_data();
    void insertion_sort();
    void display();
};
void sort_list::get_data()
{
    cout<<"How many elements two be entered ";
    cin>>n;
    cout<<"Enter the elements ";
    for(int i=0;i<n;i++)
        cin>>data[i];
}
void sort_list::insertion_sort()
{
    int temp,j;
    for(int i=1;i<n;i++)
    {
        j=i-1;
        temp=data[i];
        while(j>=0&&data[j]>temp)
        {
            data[j+1]=data[j];
            j--;
        }
        data[j+1]=temp;
    }
}
void sort_list::display()
{
    cout<<"Sorted list : ";
    for(int i=0;i<n;i++)
        cout<<data[i]<<" ";
}
int main()
{
    sort_list sort;
    sort.get_data();
    sort.insertion_sort();
    sort.display();
    return 0;
}
