Calculating the average

A very simple piece of code for the beginner in C++. It demonstrates how to calculate the average of some numbers. Uses the ?for? loop.

Cout << "Enter how many values you want to add: ";

We prompt the user to enter the number of values he wants to calculate.

int items;
cin >> items;

Create a variable that stores the number of values that should be calculated and using "cin >>" to enter the input from the user's keyboard into our new variable. Let's suppose you wanted 3 values.

double num;
double sum;
sum = 0.0;

The 'num' variable will store the numbers the user will input.
We won't use an 'int' because some of the numbers the user will enter will probably be of the 'double' type (6.4, 3.2, 145.1).
