C++ Chrono Time Library Tutorial In 12minutes ⌛

The Chrono Library has three major concepts, duration, time points and clocks. the two clocks that most programmers will use would be either steady_clock or system_clock, one being used for measuring high precision performance while the other is useful for dates and times. To make a simple timer I'll go over all of the concepts in this library to help you better understand how the library works.

At 1:37 you can save around 5s of runtime if you optimise your code by setting five_seconds = 0s;

Conversion between units time is straight forward in cpp, took me 30 mins to absorb this. I love cpp❤

first you print: test\n
second test : test_\n(extra space)
Maybe that's why there is a difference in speed.

Pretty helpful. I strongly suggest using auto less for a tutorial like this since typing is an important part of understanding what is happening.

Thank-you so so much. You save my life 😊

The mistake you make is that you cannot compare the measurements. You need to do each test say a thousend times and calculate the average. As you are working on a multi tasking system you do not know how much time each test gets. Doing only one test run can give misleading numbers. The first run showed axactly the oposite result. But your info on how to use it is super. Thank you.

this video is more of a documentation than a tutorial

In C this requires the assistance of a scheduler. In fact it's not possible without an onboard PIT.

Hello, a tutorial on the fmt library one day??(PS: You should have mentioned that the days keyword is a c+++20 feature...)

[jacko]

maybe because you had a space after test with the new line character test?

Compiler may have optimised std::endl out. Also, I personally consider "using namespace" to be a bad and lazy habit which can cause issues if you use many libraries in a project.

which compiler are you using ??? DEV C++ compiler not working with your codes

Hi im kinda new in c++.... It says that in chrono.hpp there are some undefined types... Any advice? (ratio is not defined as well if it can be helpful) Does chrono relies on other files?

Hello dude, what's your take on installing third party libraries in c/c++??
