    benchmarking - How to use clock() in C++ - Stack Overflow

    You can measure how long your program works. The following functions help measure the CPU time since the start of the program: C++ (double)clock() / CLOCKS_PER_SEC with ctime included. Python time.clock() returns floating-point value in seconds. Java System.nanoTime() returns long value in nanoseconds.

    Code sample

    std::clock_t start;
    double duration;
    start = std::clock();
    duration = ( std::clock() - start ) / (double) CLOCKS_PER_SEC;
    std::cout<<"printf: "<< duration <<'\n';...

        What is a C++ timer?
        The timer is designed for minimal-overhead, ad-hoc timing of C++ code including micro-timing down to single machine instructions. The timer is not designed for benchmarking ( benchmark or nanobench are excellent tools for this purpose) nor for detailed performance analysis. The timer has two basic modes:

        What is core timer?
        core::timer::Timer is a header-only timer for modern C++. The timer is designed for minimal-overhead, ad-hoc timing of C++ code including micro-timing down to single machine instructions. The timer is not designed for benchmarking ( benchmark or nanobench are excellent tools for this purpose) nor for detailed performance analysis.

        Is timer a C++ library?
        Timer is part of the cpp-core * family of C++ libraries. The cpp-core libraries have two primary goals: Ergonomics. In the spirit of the CppCoreGuideLines, cpp-core aspires to facilitate writing concise, idiomatic code not by force, but by providing a clear path that produces robust, easy to read code. Good code should be fun to write.

        How to measure CPU time in C++?
        You should check the current time at the start, then check the current time and subtract to get the absolute time since you started every time through the loop. You can measure how long your program works. The following functions help measure the CPU time since the start of the program: C++ (double)clock() / CLOCKS_PER_SEC with ctime included.
