What methods can be used to evaluate the efficiency of program code execution?

The efficiency of program code execution can be evaluated using several methods:

• Profiling: using profilers (e.g., Visual Studio Profiler, JetBrains dotTrace) to measure function execution time, memory usage, and other resources.
• Execution time measurement: timing specific code sections using Stopwatch or DateTime classes.
• Memory usage analysis: checking memory consumption, leaks, and garbage collection.
• Static analysis: tools that analyze code without running it, identifying potential bottlenecks.

Example of measuring execution time in C#:

using System;
using System.Diagnostics;

class Program
{
    static void Main()
    {
        Stopwatch sw = Stopwatch.StartNew();

        // Code to measure
        for (int i = 0; i < 1000000; i++)
        {
            var x = Math.Sqrt(i);
        }

        sw.Stop();
        Console.WriteLine($"Execution time: {sw.ElapsedMilliseconds} ms");
    }
}
