Answer:
Implemented the program using C++ below
Explanation:
#include <iostream>
#include <iomanip>
using namespace std;
void printIt (int numbers[],int length);
int removeAt (int numbers[], int length, int index);
void insertAt (int numbers[], int length, int insertItem, int index);
int main()
{
int numbers[] = {4,23,65,34,82,37,12,17,24,36,82,51};
int length;
int index;
int insertItem;
cout<<"Removing an item from the list..."<<endl;
cout<<endl;
printIt(numbers,12);
removeAt(numbers,12,index);
insertAt(numbers,12,insertItem,index);
system ("PAUSE");
return 0;
}
void printIt (int numbers[],int length)
{
cout<<"The current array..."<<endl;
for (int i = 0; i<length; i++)
{
cout<<numbers[i]<<" ";
}
cout<<endl;
}
int removeAt (int numbers[], int length, int index)
{
int item;
cout<<endl;
cout<<"There are "<<length<<" item(s) in the list (position 0 through 11)"<<endl;
cout<<"Enter the position of the item to be removed."<<endl;
cout<<"Enter 0 for the first item and so on: ";
cin>>item;
if (item > length)
{
cout<<endl;
cout<<"!!!!!!!!!!!!!!!!!! ERROR !!!!!!!!!!!!!!!!!!"<<endl;
cout<<endl;
cout<<"The current array..."<<endl;
for (int i = 0; i<length; i++)
{
cout<<numbers[i]<<" ";
}
cout<<endl;
cout<<endl;
