This code defines a function called calculateAverage
that calculates the average of a variable number of arguments. The function takes an integer numElements
as its first parameter, which specifies the number of elements to average. The remaining arguments are a variable number of doubles.
Inside the function, the va_list
type is used to declare a variable args
that will hold the variable arguments. va_start
is then called to initialize args
with the variable arguments.
A sum
variable is initialized to 0.0.
The Windows API functions SetConsoleOutputCP
and SetConsoleCP
are called to set the console code page to 1251.
A for loop iterates numElements
times, and inside the loop, va_arg
is used to retrieve the next double argument from args
and add it to sum
.
After the loop, va_end
is called to clean up the args
variable.
The function returns the average of the elements by dividing sum
by numElements
.
In the main
function, calculateAverage
is called twice with different number of elements and the results are stored in result1
and result2
variables.
Finally, the results are printed to the console using std::cout
.
