C++ Timer - How can I make this more efficiently? - Silent Sweat - Oct 8, 2014
I know this is probably the most shit program you've ever seen, but it is all I am currently capable of. This was made completely from scratch, without looking anything up. It took me about 20 minutes (had some problems with the logic) but I got it to work technically like a timer, although it is very inefficient (even I know this).
But I don't know how to make it like a C++ pro would.. any suggestions on improvement?
Here is the pastebin code source: HERE

At first thought, use boost it has a simple way to manage time.

...or
PHP Code
<?php
clock_t start = clock();
// ...
clock_t end = clock();
double elapsed = double(end - start) / CLOCKS_PER_SEC;

Can you elaborate on that? Please, I am a beginner. Explain to me what that does, and how I can replace my code with it.

What is there to elaborate on? The code is self explanatory. It takes the current measurement of time, // ... indicates some kind of code that takes time to execute, and an end measurement of time is stored in a variable. To find the time elapsed, it's the delta between these 2 calculated values, and the macro CLOCKS_PER_SEC is a defined value for the "clocks per second", thus elapsed is a measurement of elapsed seconds.
