clrscr();
printf(" enter how many nos u wanna putin");
scanf("%d",&n);
if(n<1||n>20)
{
printf(" invalid input");
return;
}
printf(" Enter the elements into the array one by one");
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
}

printf("the elements in the array");
for(i=0;i<n;i++)
{
printf("%d",a[i]);
}

printf(" Which address field will occupy the new element");
scanf("%d",&ins);--ins;

printf(" enter the elemnt u wanna put in");
scanf("%d",&ent);
for(i=n;i>=ins;i--)

Answer / kingkill

// The Process of adding new element into an array is known as insertion. Array can be inserted in the beginning or the end if the array is unsorted.
//Insertion can only be performed in an array if the memory space initially allocated is not full, i.e the number of elements in the array is less then the size of the array.

#include <iostream>
using namespace std;
#define MAX 20

int main ()
{
int A[MAX],i,pos,j,size,item;
cout<<" Enter the number of elements in the array : ";
cin>>size;
cout<<" Array size defined is "<<size<<"\n";
if(size>MAX) // Checks the array size ( defined )
{
cout<<" The Maximum Size is 20 \n";
}

cout<< " Enter the elements in sorted order: \n";

for(i=0;i<size;i++)// Elements inserted equal to size
{
cin>>A[i];
}

cout<<" Enter the element to be inserted : ";
cin>>item;
if(size==MAX) // Checks if free array space is free
{
cout<<"The Aray is Full \n";
}

for(i=0;i<size;i++)
{
if(item<A[i])
{
pos=i;
break;
}
}
if(i==size)
pos=size;
for(j=size;j>pos;j--)

A[j]=A[j-1];
A[j]=item;
size++;

cout<<" Array elements after insertion : ";
