(Solved Homework): Use visual studio to create a new C++ project. Your required in this task to impalement your own vector class. Your class is named custom_Vector…

Here is the code for you:

#include <iostream>
using namespace std;

class Custom_vector
{
int maxSize;
int currentSize;
string array[10];

public:
//A default constructor that initialize your custom vector objects.
Custom_vector()
{
maxSize = 10;
currentSize = 0;
}
//A destructor to release the memory to the heap.
~Custom_vector() {}
//push_back(string item) function that appends elements to the end of the vector.
void push_back(string item)
{
if(currentSize < maxSize)
{
array[currentSize] = item;
currentSize++;
}
else
cout << “Cannot pushback elements to vector.” << endl;
}
//pop() function that removes the last element of your vector and returns it.
string pop()
{
if(currentSize != 0)
{
currentSize–;
return array[currentSize];
}
else
cout << “Cannot pop elements from vector.” << endl;
return 0;
}
//disp() function that displays the elements of the vector.
void disp()
{
for(int i = 0; i < currentSize; i++)
cout << array[i] << endl;
}
//size() function that returns the number of elements in the vector.
int size() { return currentSize; }
//at(int index) function that returns the element at the position index.
string at(int index)
{
if(index-1 < currentSize)
return array[index-1];
else
{
cout << “The index(” << index << “) is out of range!” << endl;
cout << “The vector includes only ” << currentSize << ” elements!” << endl;
return “”;
}
}
};

int main()
{
Custom_vector vector1;

vector1.push_back(“apples”);
vector1.push_back(“bananas”);
vector1.push_back(“pineapples”);

vector1.disp();
cout << “The vector size = ” << vector1.size() << endl;

cout << vector1.at(10) << endl;

cout << vector1.at(2) << endl;

cout << “Pop => ” << vector1.pop() << endl;

cout << “The vector size = ” << vector1.size() << endl;

return 0;
}

And the output screenshot is:
