CODING:
#include<stdio.h>
#include<conio.h>
void insertion_sort(int *,int);
void display(int *,int);
void main()
{
int i,n,list[20];
clrscr();
printf("How Many Enter The Element:");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
  printf("Enter the number:");
  scanf("%d",&list[i]);
}
insertion_sort(list,n);
display(list,n);
getch();
}

void insertion_sort(int list[],int n)
{
int p,i,temp=0,k;
list[0]=-0;

for(i=1;i<=n;i++)
{
   p=i-1;
   temp=list[i];

while(temp<list[p])
{
list[p+1]=list[p];
p--;
}  

list[p+1]=temp;
printf("\n STEP=%d",i);
