/* Write a function float average ( int n ) that accepts one parameter 
that indicates amount of float numbers that your function reads from the user. 
The function returns the average of the input numbers. 
For example, if the parameter is 4 and user input 1.0, 2.0, 3.0, 4.0 , 
function returns 2.5 ( (1.0 + 2.0 + 3.0 + 4.0)/4).
Write a program, that reads one integer that indicates 
the amount of the input numbers. The program uses function average to 
find an average of the input numbers.
