C++ Program to remove duplicate numbers in an array

Object: Write a program that takes numbers as input and returns the result with all the duplicate numbers removed For example, if the input Array is {0, 1, 2, 2, 3, 4, 5, 6, 8, 8, 9, 1, 2}, the output will be {0,1, 2, 3, 4, 5, 6, 8, 9}. 

Code:

void main()
{
int i, j, k, n, num[100];
cout<<“How many Numbers Your Enter?\n”; cin>>n;
cout << “Enter Any “<> num[i];
}
for (i = 0; i < n; ++i)
for (j = i + 1; j < n;)
{
if (num[i] == num[j])
{
for (k = j; k < n – 1; ++k)
num[k] = num[k + 1];
–n;
}
else
++j;
}
cout << “\nDuplicate Numbers removed. \n”;
for (i = 0; i < n; ++i)
cout << num[i] << ” “;

getch();

}

#include<iostream>
#include <conio.h>

using namespace std;

void main()
{
	int i, j, k, n, num[100];
	cout<<"How many Numbers Your Enter?\n";
	cin>>n;
	cout << "Enter Any "<<n<<" Numbers :\n";
	for (i = 0; i < n; ++i)
	{
		cin >> num[i];
	}
	for (i = 0; i < n; ++i)
		for (j = i + 1; j < n;)
		{
			if (num[i] == num[j])
			{
				for (k = j; k < n - 1; ++k)
					num[k] = num[k + 1];
				--n;
			}
			else
				++j;
		}
	cout << "\nDuplicate Numbers removed. \n";
	for (i = 0; i < n; ++i)
		cout << num[i] << " ";

	getch();
}
