I'm using VS and coding in Java, C++ and C#. What are the methods to use to display the time it takes for the program to execute in ms?
Click For Summary
Discussion Overview
The discussion centers around methods for calculating program execution time in various programming languages, specifically Java, C++, and C#. Participants explore different timing functions and tools available in different operating systems, as well as considerations for accuracy and overhead.
Discussion Character
- Technical explanation
- Exploratory
- Homework-related
Main Points Raised
- One participant mentions using
QueryPerformanceCounter()for high-resolution timing but notes it includes overhead from other tasks. - Another participant discusses
GetProcessTimes(), suggesting it should exclude overhead from other processes but indicates it may still include interrupt overhead. - A different participant points out that on UNIX-based systems, the
timecommand can be used to measure execution time and references a related paper. - One participant requests clarification on the specific namespace, class, and methods to use in C# for timing execution.
- Another participant suggests considering profiling for critical applications, mentioning that profilers can provide detailed timing for each function in the code.
Areas of Agreement / Disagreement
Participants express various methods and tools for measuring execution time, but there is no consensus on the best approach or method, as different tools may have different overheads and applicability depending on the context.
Contextual Notes
Some methods discussed may have limitations related to overhead from other processes or interrupts, and the accuracy of timing may depend on the specific environment and implementation.
