How do I compare different algorithms in C++?

How do I compare different algorithms in C++?

You can compare algorithms in C++ by analyzing their time complexity, space complexity, and performance on various data sets.

What metrics should I use for comparison?

Common metrics include execution time, memory usage, and the number of operations performed.

Can you give an example of comparing sorting algorithms?

Sure! You can implement quicksort and mergesort, then measure their performance on large arrays to see which is faster.

Are there any libraries that can help with this?

Yes, the C++ Standard Library provides algorithms like std::sort, which you can use as a benchmark for your comparisons.
