Using 'auto' type deduction - how to find out what type the compiler deduced?

Question

How can I find out what type the compiler deduced when using the auto keyword?

Example 1: Simpler

auto tickTime = 0.001;

Answer 1

As a side note, to effectively print out the value in nextTickTime you should explicitly convert to a suitable std::chrono::duration and output the result of duration::count.

using std::chrono::duration_cast;
using std::chrono::seconds;

auto baseTime = ...;
std::cout << std::setprecision(12) << duration_cast(nextTickTime - baseTime).count()
    << std::endl; // time in seconds
