show_int_vector method RETURNS MEMORY LOCATION FOR EVERTHING EXCEPT FOR LAST VALUE.

main

```
#include "my_int_vector.h"
#include <iostream>
using namespace std;
int main()
{
my_int_vector b(0);
b.push_back(10);
//b.show_int_vector(b);
b.push_back(122);
b.show_int_vector(b);
//b.push_back(20000);
return 0;
}
```

Interface

```
class my_int_vector
{
public:
//constructor to create an array
my_int_vector(int intial);
//prints out the vector that contains the numbers
void show_int_vector(my_int_vector& b);
//returns value at arrayindex
int at(size_t arrayindex);
//returns value at arrayindex
int operator[](size_t array_index);
//add value to end of array
void push_back(size_t user_number);
//delete value from end of array
void pop_back();
//returns total number of elements that can be stored in the list
int capacity();
private:
//array to store numbers
int* numbers;
//array of temp values
int* temp;
//array of values which need to be printed which would be the valid ones
int* print;
//
size_t array_index;
};
```
