"Write a program in C++ to find the sum and average of given numbers using Arrays."

Please help me find out the source code in C++! please!

Ok here it is:
Code:
```#include <iostream>
#include <conio.h>

using namespace std;

int main (int argc, char *argv[])
{
int num[100];
int n;
register int i;
int sum = 0;
float avg;
cout << "Enter number of items in array: ";
cin >> n;
for (i = 0; i < n; i++)
{
cout << "Enter the " << i+1 << "th number: ";
cin >> num[i];
sum += num[i];
}
avg = (float) sum/n;
cout << "Sum is " << sum << "\nAnd Average = " << avg;
getch();
}
```
But if you wanna learn programming for yourself, try coding it yourself. I have given you the program, get the idea from it and try to write your code yourself.
Anyway, its my first try on C++, had never coded in C++.

Dear Friend,

The following coding to calculate the sum and average of an array element using C program.

Code:
```#include<stdio.h>
main ()
{
int array[100];
int n,i,sum=0;
float avg;
printf("Enter number of elements in array:\n");
scanf("%d",&n);
for (i = 0; i < n; i++)
{
scanf("%d" ,&array[i]);
sum += array[i];
}
avg = (float) sum/n;
printf("The sum is :%d\n",sum);
printf("The sum is :%f\n",avg);
}
```
