I am a brand new programming student, so please forgive my ignorance. My assignment states:
Write a program that declares an array of 10 integers. Write a loop that accepts 10 values from the keyboard and write another loop that displays the 10 values. Do not use any subscripts within the two loops; use pointers only.
Here is my code:
#include "stdafx.h"
#include <iostream>
using namespace std;
int main()
{
const int NUM = 10;
int values[NUM];
int *p = &values[0];
int x;
for(x = 0; x < NUM; ++x, ++p)
{
cout << "Enter a value: ";
cin >> *p;
}
for(x = 0; x < NUM; ++x, ++p)
{
cout << *p << " ";
}
return 0;
}
I think I know where my problem is. After my first loop, my pointer is at values[10], but I need to get it back to values[0] to display them. How can I do that?
