How to make stopwatch in c++

Question

Stopwatch

Answer 1

A hint would be to look into <ctime> or <chrono>.

Get the time upon begin point, then store it inside a variable. Get the time upon completion point and store it inside another variable. Deduct the latter with the former, and convert to seconds.

Answer 2

It's better to use modern time libraries, like <windows.h>, which are more precise than <ctime> :)
