C++ program to sort the numbers by using insertion sort

In this post, we will write a C++ program to sort the numbers by using insertion sort. the program will print the list before the sorting of the list and then also print after sorting the list.

C++ program to sort the numbers by using insertion sort.

#include<iostream>
#include<conio.h>
#include<stdlib.h>


int main()
{
    system("cls");

    int a[10];
    int i,min,temp,ptr;

    a[0] = -32678;

    for(i=1;i<=9;i++)
        a[i] = rand()%100;
    for(i=1;i<=9;i++)
        std::cout<<a[i]<<"\t";

    std::cout<<std::endl<<"The list after sorting"<<std::endl;

    for(i=1;i<=9;i++)
    {
        temp = a[i];
        ptr = i-1;

        while(temp < a[ptr])
        {
            a[ptr+1] = a[ptr];
            ptr = ptr-1;
        }
        a[ptr+1] = temp;
    }
    for(i=1;i<=9;i++)
        std::cout<<a[i]<<"\t";

    getch();
    return 0;
}



Output

46  30  82  90  56  17  95  15  48
The list after sorting
15  17  30  46  48  56  82  90  95
